  • There's no hope in this world.

Page 3

  • The blue of the sky...
  • ...the chirping of insects...
  • ...the scenery outside... the singing of birds...
  • I don't care... about any of it.
  • It's better not to know.
  • This is my only world.

Page 4

  • I'm going to spend my whole life here.
  • Because that's my fate.
  • Japanese Language Drills
  • Torajiro

Page 5

  • I'm going to die.
  • I've been alive for 10 years, but I've never once been outside.
  • All I've ever seen are Mom and Dad's tears.
  • I wish they would've smiled for me, at least at the end.
  • HELLOOO!!
  • ?!
  • I am the great Shinigami, Zanluke!
  • I'm here to reap your soul!
  • Who the hell are you?!

Page 6

  • What, you're not dead yet?!
  • This boy has been fighting his illness his whole life!
  • At least let him pass on in peace...!
  • !!
  • What's with that giant stag beetle?!
  • You like stag beetles?!
  • Stop! Don't touch Tomoya!
  • Listen to the story of the stag beetle I just caught!!
  • Wait! Don't die yet!
  • I'll share my power with you!
  • Just listen to my story!!
  • TOMOYAAA—!

Page 7

  • Illness completely cured!
  • Huh?
  • It was the stag beetle I caught!
  • I'm... alive...
  • Tomoya!
  • Hey!
  • For a miracle like this to happen...!
  • Mom, Dad! Nothing hurts anymore!
  • About that stag beetle...
  • Oh, you're a god...! How can we thank you?
  • We'll do anything!
  • Shut up! Gimme that stag beetle!!
  • Is that all you want?!
  • Here you go!

Page 8

  • Discharged from the hospital.
  • This is my room... It's amazing...!
  • RAAAAGH!
  • Stag Beetle Bro!
  • I got chewed out by my boss because of you!
  • This was a fake too, you tricked me?!
  • No matter how you look at it, it's a cushion...
  • Take responsibility!
  • Huh...? Um, so... should we go catch some stag beetles?
  • Let's go!

Page 9

  • Whoa!
  • There are so many huge ones!
  • My dad told me about this place.
  • This one! It's so round, it looks strong!
  • This is all thanks to you for saving me, big bro.
  • H-Hey, hey...
  • Thank you so mu—
  • We've gotta come here every year now!
  • He doesn't listen to a word I say...
  • Look at this!
  • They've combined into a Z-Stag Beetle!
  • This guy...

Page 10

  • Look! Isn't it cool?!
  • You caught a lot!
  • I'm going to evolve these guys and go defeat him!
  • Him?
  • They can evolve?
  • In my head, they can!
  • It's the ultimate stag beetle that will carry me through the sky and sometimes even become my weapon!
  • I need lots of stag beetles for the evolution!
  • Is he... a little weird in the head...?

Page 11

  • We are the mighty Stag Beetle Alliance!
  • Let's come here to catch them every year!
  • Every year...
  • It's a promise between men!
  • Give the big ones to me!
  • Stag Beetle Bro...
  • You're like Gian.
  • Who are you calling a Jumbo Apple Snail?!
  • Ow!
  • And so, it became a yearly promise.

Page 12

  • He became a middle schooler.
  • This town is so rural, I can't make any friends.
  • Time for stag beetle hunting!!
  • Stag Beetle Bro!
  • Could you please stop breaking my window every time you show up?!
  • This is the entrance, isn't it?
  • Of course it's not!
  • Another day.
  • I'll just leave the window open from now on!
  • His room now had zero security.

Page 13

  • Oh! Mr. Stag Beetle, you're here?!
  • Mom!
  • Look, Mom! Big bro broke the wall!
  • It's fine, it's fine! My husband's a carpenter.
  • That's why he gets so carried away!
  • More importantly...
  • Wanna go...?
  • Are you a kid?!

Page 14

  • You get in too!
  • I'm way too old for that.
  • He's always...
  • ...dreamed of this...
  • He never got to play in the water or anything...
  • Mom!
  • I just thought, maybe it's not too late, even now...
  • Dammit—!

Page 15

  • Maybe I'll go home after a dip in the pool and some watermelon today.
  • I'm getting a little old for stag beetles, after all.
  • From now on, I'll just keep him happy with video games or something...
  • I closed it because I didn't think you were coming!
  • Uwaaah!
  • How could I, the great Zanluke...!
  • What happened?!
  • There's no way I can go back to work without catching some stag beetles!
  • Then go back!

Page 16

  • He became a high schooler.
  • I wonder if Mr. Stag Beetle will come today.
  • Honestly, I hope he doesn't come today.
  • After all, today is a big day for me.
  • He got a girlfriend.
  • Hello.
  • Welcome, Kana.
  • Today is their at-home date.
  • My room's a bit of a mess, but...
  • Thanks for having me.
  • If I'm lucky, maybe we can take things to the next level...!

Page 17

  • Oh! Tomo, you keep stag beetles!
  • Yeah, I caught them last year.
  • You might not be able to tell, but I'm actually an expert at catching stag beetles.
  • There's a spot deep in the woods where you can catch a ton. You set traps at night...
  • Huh... I'm surprised...
  • A-Anyway...
  • Let's watch a movie today.
  • Sounds good!
  • It's that horror movie that was a big deal last year.
  • Hey...
  • It's kind of exciting, being all alone like this.

Page 18

  • Ka...
  • STAG BEETLE HUNTING TIME!
  • I knew you'd show up!

Page 19

  • Who is this guy?!
  • Who are YOU?!
  • Kana... is picking a fight with him...?
  • I'm Tomo's girlfriend!
  • You are?!
  • I had all sorts of plans for what we were going to do today...!
  • And now it's all ruined!
  • I'm his stag beetle boss!
  • First I'm hearing of it.
  • Don't you butt into a promise between men!
  • Tomoya is mine!
  • Who the hell is Tomoya?!
  • I can't believe you don't even know his name!
  • I know this execution method... "Take him down!!"

Page 20

  • Alright then, let's settle this with a stag beetle battle!
  • Bring it on!
  • Sigh...
  • We'll compete in these woods!
  • What about our at-home date?!
  • Don't underestimate my years of stag beetle experience!
  • Unbelievably, Kana won!
  • Noob, lol
  • Dammit...
  • Just kidding. You're not half bad.
  • Master...!
  • It's been a while since I've felt this fired up.
  • I acknowledge you!
  • And you just left me behind!

Page 21

  • He became a college student.
  • Tomo, sorry to keep you waiting!
  • Kana!
  • Kana, your car is awesome!!
  • Hehe... I splurged just for today.
  • Amazing!
  • Is it okay with Stag Beetle Bro, since he usually comes around this time?
  • It's fine, I left him a note.
  • I'm surprised you're into camping, Kana!
  • Because I'm a hopeless introvert.
  • What's that supposed to mean?

Page 22

  • We're here!
  • What a great view!
  • Looks like there might be some rare stag beetles here!
  • Yeah, looks like it.
  • Did you bring bait?
  • I brought enough for you guys, too!
  • How thoughtful.
  • I'll go after I set up the tent.
  • Let the stag beetle camp begin!

Page 23

  • Awesome!
  • It's a meat pincer attack!
  • Tomoya, you're a great cook!
  • It's my only skill.
  • I wonder...
  • You've got a great boyfriend, right?
  • After we eat this, let's go check the traps!
  • Let's all go together!
  • I caught one!
  • Let the small ones go.
  • Something feels off...

Page 24

  • That was fun.
  • Don't sleep with your stomach showing.
  • Should we get some sleep?
  • Huh? There are only two sleeping bags.
  • We brought enough for everyone, right?
  • Zzzzz...
  • ...!
  • ...
  • ZZZZZ!
  • Why are you here?! Stag Beetle Bro!
  • Huh?!
  • You blended in way too well!

Page 25

  • You just tagged along to catch stag beetles, didn't you?!
  • I wasn't planning on catching stag beetles today!
  • Today, I was supposed to be with Tomo, out in nature...
  • ...and I had all sorts of plans for what we were going to do!
  • Kana...
  • I skipped out on important work to be here, you know!
  • Then go back to work!
  • That's it, I'm done!
  • I'm never coming back!
  • Be my guest!
  • Kana...! That's going too far!

Page 26

  • I went too far...
  • I was having fun catching stag beetles, too.
  • He always gets in the way, so we can't do this...
  • ...or that...!
  • I just blurted out how I really felt...
  • Kana...
  • What if he never comes back...!
  • It's okay... Big Bro will forget all about it and come right back...
  • See? He's here!
  • I came back because I was feeling conflicted!

Page 27

  • ...?
  • A stag beetle...?
  • There are more of them...
  • These are my precious comrades.
  • I'll give them to you...
  • Huh?!
  • So...
  • What are you going to do?
  • What do you want?!

Page 28

  • Is this... how we make up...?
  • What?!
  • That one is the king of the forest I caught last year.
  • He's super strong, but also nimble.
  • This one is small, but he's smart and fast.
  • They're all the strongest stag beetles, which I raised by my own hand.
  • I'll give them to you... if you make up.
  • Big bro, I went too far, too.
  • We don't need the stag beetles, let's just make up!

Page 29

  • They're all your precious family, aren't they, big bro?
  • And they want to go back to you...!
  • I'm sorry! All of you...!
  • Let's go catch more first thing tomorrow morning!
  • Okay!
  • You can sleep next to me, big bro.
  • His love for stag beetles is the real deal, at least.
  • I hope you never change.
  • What was that?

Page 30

  • He became a working adult.
  • I underestimated adult life... There's way too much overtime...
  • Tomoyaaa...
  • Stag Beetle Bro?!
  • I was defeated...
  • Beaten to a pulp...
  • Who did this to you?!
  • By the Great King of the Shinigami World...!
  • Calm down! I'm listening.
  • Ghh...

Page 31

  • A long time ago, I was a warrior in a place called Shurado!
  • A world in the afterlife where all they do is fight.
  • We're getting a backstory, out of nowhere?
  • Is that the name of a country in the afterlife?
  • I collected a ton of Kabuto there and even conquered the whole realm!
  • Kabuto? Not stag beetles?
  • But I wanted to fight someone even stronger!
  • Wow.
  • Gimme your Kabuto!!
  • So I challenged the Great King of the Shinigami World for his Kabuto!
  • He looks like a kindergartener from some foreign country.
  • He's so spiky.
  • You just challenged him? That's pretty aggressive.
  • And then... I lost...!
  • What preschool does he go to?
  • Well, he's the Great King, so he must be strong.
  • So full of energy!
  • Don't spill your cola, okay?
  • And then, he said this to me...!
  • Those horns... are they a stag beetle?
  • They might make you look strong, haha.
  • So that's the origin story!

Page 32

  • I became a Shinigami just so I could defeat him!
  • So you've changed careers too, big bro.
  • Take your shoes off.
  • This is my third job.
  • Bankruptcy, power harassment...
  • We're from different worlds, but it's the same story.
  • Seriously?!
  • So you want to defeat the Great King too, Tomoya?!
  • Uh, no...
  • That's not what I meant by 'the same story'...
  • He really never listens...
  • Let's go find a super strong stag beetle that can exploit his weakness!
  • But you're drunk and can barely stand...

Page 33

  • Saved by this goofy Shinigami...
  • I'll carry you!
  • Are you really going to go through all that trouble?
  • Of course!
  • It's been almost 20 years...
  • He's kind of a handful for a hero.
  • Big Bro Zanluke is...
  • ?!
  • How do you know my great name?!
  • You told me when we first met.
  • How could I ever forget?
  • You don't change, big bro...
  • ...but I do.

Page 34

  • They got married.
  • Kanaaa!
  • Let's have a coffee break!
  • Oh—does it have caffeine?
  • ?
  • Yeah, it does.
  • From now on, it's decaf for us.
  • For our little ones.
  • Tomo! You're spilling it! You're spilling it...!

Page 35

  • Kana, thank you!
  • Oh, stop being so dramatic!
  • Wait, 'little ones'? Does that mean we're having twins?
  • You got it!
  • I'm so happy...!
  • Let's build a wonderful, happy family of four!
  • Don't say that, Tomo!
  • If you say something like that,
  • he's bound to show up!

Page 36

  • You had kids?!
  • Two of 'em!
  • Watch your language!!
  • Alright! I'll make them both my loyal followers!
  • Hey.
  • Your foot.
  • Get it off.
  • And another thing.
  • If you break the window again, you're banned from this house.
  • Wh...? Right.
  • Fixing windows is expensive, you know! If you break it again, I'm sending the bill straight to your boss!
  • We're having babies! That means no shouting! And no swinging that net of yours around!
  • I gave up trying to reason with him ages ago...
  • Kana, you're amazing!

Page 37

  • They're here!!
  • One of them is always crying!
  • Are twins always this hard...?
  • Even with both of us, we're short-handed...
  • He should be here soon... Big Bro...
  • Maybe we can get him to help out a little with childcare...?
  • What?!
  • NO WAY! IMPOSSIBLE!
  • That would just be like having a third baby!
  • Is he really that bad...?

Page 38

  • Taking care of brats?!
  • When are we supposed to go stag beetle hunting?!
  • Sorry... It's impossible this year...
  • I feel like I'm going to die from lack of sleep and stress...
  • WHAT?!
  • I'm only lending you my help! When these two get bigger, they have to promise to join the Stag Beetle Alliance!
  • So! What do you need me to do?!
  • Change their diapers and put them to sleep, got it!
  • Should I wash these bottles?!
  • Huh...? He's actually really good at this.
  • Is he the type who can do anything on instinct...?
  • What an unexpected talent...

Page 39

  • Several years later.
  • They've gotten so big!
  • The time just flew by, didn't it?
  • I wonder if Dad has met Big Bro yet.
  • I'm sure they've met.
  • I'll never be able to forget Big Bro, but...
  • ...the fact that you lived, Tomoya...
  • ...got married, and even gave me grandchildren...
  • ...means I have no regrets.
  • Mom...
  • Three boys!
  • It's going to be a handful, but do your best!
  • Wait, are you including Stag Beetle Bro in that count?

Page 40

  • We're going camping!
  • Just be good until we're ready to leave.
  • Stag beetle camp!
  • Stag Beetle Bro!
  • This is not what we need right before we leave.
  • I'm going to put our bags in the car.
  • That's it, you're banned!
  • What did you say?!
  • I'm gonna tell your mom!
  • W-Wait! I'll fix it!
  • You can fix it?!
  • I have a talisman that can rewind time for objects!
  • You had an item that convenient and you're only telling us now...?
  • Whoa! It's really fixed!
  • I wanna see!!
  • Hey... let your dad take a look, too.

Page 41

  • Do Shinigami get old?
  • Old? Yeah, we do.
  • I think we die after about a thousand years.
  • So about ten times longer than a human.
  • How old are you, big bro?
  • I don't know! The great me is never gonna die!
  • Because I'm an exceptional asset!
  • A true professional!!
  • I even recently became a high-ranking officer in charge of protecting the realm!
  • Cough
  • So you have an official position now, big bro...?
  • Of course! The great me can do anything!
  • No sesame seeds!!
  • Even though you just skip work to catch stag beetles all the time?
  • I-I do guide souls to the afterlife, I'll have you know!

Page 42

  • Well, don't you worry!
  • Even when I become the top dog, I'll still make time to hang out with you, Tomoya!
  • Haha, you don't have to force yourself.
  • A man's gotta take care of his stag beetle buddies!
  • And you'd better keep giving the big ones to me!
  • He never changes.
  • We're friends.
  • W-We're not?!
  • I'm kidding.
  • We are friends, but...
  • ...to me, you're a little different.
  • Don't joke around at such an important moment!
  • Dad! Big Bro! Let's go check the stag beetle traps!
  • Ow, ow!
  • Yeah!

Page 43

  • Gimme the big one!
  • Come on, let the kids have it...
  • Big Bro, aren't you hot in that outfit?
  • I've got a talisman on it that makes it more breathable!
  • It feels like I'm walking around naked!
  • Now I'm worried for a different reason.
  • Today, I'll let you have the big one, Tomoya!
  • It's fine... You'll take better care of it than I would.
  • It's hot this year!
  • Sure is.
  • I'll carry you home!

Page 44

  • ...moya.
  • Tomoya.
  • Tomoya, I'm going to close the window now.
  • No...
  • It's fine.
  • I leave it...
  • ...open...
  • ...on purpose.
  • Please...
  • ...leave it...
  • ...as it is.

Page 45

  • And it's dangerous to leave the screen door wide open.
  • Yo!
  • Wha—?!
  • Big... Bro...
  • He's trespassing!
  • He's a...
  • ...dear friend.
  • of mine.
  • Could you...
  • ...give us...
  • ...a moment?
  • How are Junya and Raiya?
  • They both...
  • ...had kids.
  • Twins.
  • So I hear.
  • That sounds like a handful.
  • Well, no matter! The great me is here now!

Page 46

  • So when are you gonna be well enough to go stag beetle hunting?
  • That's...
  • ...not something I can do...
  • ...anymore.
  • ...I think.
  • I don't think I can do that anymore.
  • What?!
  • ...Fine! The great me will bring them to you every day!
  • Here's today's haul!
  • I already...
  • ...went and caught some.
  • Big Bro...
  • ...there's something...
  • ...I've always wanted...
  • ...to ask you.
  • What is it?
  • The afterlife...
  • ...what kind of...
  • ...place is it?

Page 47

  • It's full of morons!
  • I'm the only one who takes things seriously!
  • They're all a bunch of carefree fools living in la-la land!
  • Haha...
  • I'm...
  • ...worried.
  • But the food is great! And the towns are beautiful!
  • It's a nice place!
  • I see.
  • That's...
  • ...good.
  • I see your mom and dad there all the time!
  • They still
  • haven't been
  • reincarnated
  • yet.
  • Apparently that bastard Enma threw out his back, so it's taking a while to get through all the judgments.
  • You should call him...
  • ...Lord Enma.
  • Lord Enma.
  • Right?
  • ...
  • Kana...
  • How...
  • ...is she?

Page 48

  • Kana? Yeah, she visits me all the time.
  • She seems to be worried about you, since she had to leave you behind.
  • Hee...
  • Hehe...
  • It's good...
  • ...that she's...
  • ...doing well.
  • Soon...
  • ...you'll be able...
  • ...to see...
  • ...everyone...
  • ...I guess.
  • Are you... going to die soon?
  • You can tell...
  • ...just by looking,
  • can't you?

Page 49

  • You came...
  • ...to reap my soul,
  • didn't you?
  • Nah, I just came to show you this stag beetle.
  • Hehe.
  • That's so...
  • ...like you, Big Bro.
  • This...
  • ...hospital room...
  • ...is where...
  • ...you and I...
  • ...first met.
  • Was it? I don't remember!
  • It's changed...
  • ...a little,
  • ...but...
  • ...I was here...
  • ...for so long...
  • ...that I remember...
  • ...it well.
  • I don't really get it, but that's incredible!
  • I...
  • ...you know...

Page 50

  • Back then...
  • Hhh—
  • ...the thought of dying...
  • ...was so...
  • ...scary.
  • Kids are scared of everything.
  • Can't be helped!
  • But you saved me, Big Bro...
  • I cried the first time I ever went outside.
  • That's because the fresh air is amazing!
  • Even the great me cries sometimes!
  • I got married, I had kids...
  • I really don't have any regrets.
  • Those brats got so big!
  • And I'm proud of 'em too!
  • ...Or so I thought.
  • I guess... I'm still scared of dying.
  • Hey, hey...

Page 51

  • I am the great Shinigami who once conquered the heavens!
  • Leave what comes after death to me!

Page 52

  • Let's go stag beetle hunting in the afterlife, too!
  • Yeah.
  • If you're with me, Big Bro...
  • ...then maybe dying is something I can look forward to.

Page 53

  • Should we go hunting as soon as we get there?!
  • Or maybe you want to see Kana and your folks first.
  • Hey, that first stag beetle you and I caught! It's gotten massive.
  • So it's still around.
  • It's gotten even bigger.

Page 54

  • Come on over to my place! I'll show you!
  • Your home... is nice.
  • Yeah.
  • I know, right?!
  • Big Bro.
  • What is it?
  • Thank you.
  • For what?
