Title page
Beast & Man & Hero
Page 1
B: Hero? You’re a hero?
B: Hahahaha, I am a monster
B: you’re a puny hero who knows nothing of my terrifying power, you came here recklessly seeking fame
Sui: that head, it’s…
Page 3
B: don’t make me laugh! You’re trash who doesn’t know how weak you are
B: you…you are ?!
Page 4
You….are….ahhhhhh
Page 5
S: huh? Who? Have we met?
B: I don’t remember how I lost, he must have used cheap tricks to beat me, how despicable
B: I’m so lucky to meet you again like this.
B: This time I’ll definitely…
B: give you a full taste of monster Bakuzan’s killer moves!
S: who da fook is dat guy?
Page 6
B: dark hell killing technique – crying devil lower kick!
Page 7
S: you guys are still alive?
B: not bad, you’re still standing
B: hehehe, you’ve stopped moving, how’s that?
B: are you terrified? This unimaginable difference in power. Are you regretting your decision of coming here?
Page 8:
B: Bear killer middle kick!
Sui: he can’t dodge in order to protect the fallen participant. This is bad. Even he can’t tank that many hits from monster Bakuzan
Page 9
Sui: save yourself first! Duck!
B: Shura frontal strike!
B: it’s time we hear you cry!
Page 10
B: this is to return the favor for what you did to me during the contest!
B: I’m not going to spare your life, ahahahaha
B: tsk, no reaction?
B: has he lost his mind due to fear?
B: How boring…
B: Let’s end this. Turn to dust with the rest of the trash!
Page 11
B: Hellish chop!
S: it’s no good, I can’t remember who he is
Page 12
Suiryu: !!!!
Page 13
Page 14
S: what were you...
S: meh forget it
Page 15
S: man, you’re quite unlucky. All this after finally becoming champion
S: anyway the monster is dead, better luck next time
Sui: ah…thank you…for saving…me
Page 16
Sui: who are you, really?
Sui: a h…hero?
S: I’m Saitama, a professional hero…for now
Page 17
Sui: Saitama…? So…you concealed your identity in order to participate in the superfight tournament?
S: shit….now he knows
Sui: but what for? You even wore a wig…
Sui: secret order from the Hero’s Association?
S: nah, I wanted to experience martial arts, there’s also the prize money…
S: the “hero hunter “ has been causing quite a stir lately, rumor has it he’s a martial arts master, it got me interested
Page 18
Sui: is that so…you wanted actual experience fighting martial arts masters…in order to devise strategy against them…
S: nah, not really…I just happened to come across a ticket…to be honest, I came because….I was free
Sui: you were…free…
Page 19
Sui: I’m alive thanks to you
Sui: your timing was also impeccable
S: huh? Should I have arrived earlier?
Sui: no no….it’s better that you got here after “Gouketsu” left. You avoided confronting a really strong monster, otherwise we would both be finished.
Sui: I was a baby next to him….that guy’s strength was almost like cheating
Page 20
G: I must have the Doctor fix me ASAP and return to the battlefield
G: Though it was due to my own carelessness, I cannot let a monster strong enough to finish me with one punch roam the cities freely.
Page 21
G: Gouketsu is in a whole new dimension. He’s likely stronger than any monster I’ve fought in the past. I’m sure you will be very impressed by his strength too, Saitama sensei
G: I should join forces with the S-class heroes and sensei, and hunt Gouketsu down together!
G: that’s the necessary approach
Sui: it’s better to stay inside for now, other terrifying monsters are also gathering
S: for real? That’s what’s going on? Am I late to the party after all?
Page 22
Sui: they found a way to transform humans into monsters. The number of dangerous monsters will only increase from now on
Sui: the monster you just beat was a human before too, your opponent in the second round
Sui: but now he’s turned into this, you probably can’t recognize him
Sui: in any case, this is a critical time, we shouldn’t move about until we get in contact with others, I don’t think ambulances can be dispatched under these circumstances, staying here would be our best bet
S: OK. I guess this isn’t playtime. Where is that monster?
Sui: Eh, it’s over there, he’s the one who destroyed the stadium wall
Page 23
S: ah, that explains the loud noise I heard earlier
Sui: that’s right…I suppose you have no choice but to fight the monsters as a hero. You guys really are something
Sui: gather the heroes on masse, defeat the monsters….get in touch with the police….help the civilians…is there anything else?
Sui: in any case, you need to make serious and thorough preparations before taking on that guy
Page 24
S: I’ll be back in a sec
Sui: Wait…You…hold on!!!
Page 25
Sui: did you hear what I just said? Didn’t I tell you?
S: I heard you fine…What?
Sui: No! You’re not getting it!
Sui: the organization called monsters association is destroying the cities!
Sui: you must wait until things die down…hold on a second! What do you think would happen if you were surrounded by monsters stronger than you?
Sui: Gouketsu was a supreme martial artist to begin with, more skilled than me, faster than me, with great power to boot!
Sui: you’ll be slaughtered!
Page 26
S: So he’s a martial arts master too eh? That’s kinda interesting
S: speaking of, I’m having some digestive problems
Sui: Saitama kun!
S: hey you, take it easy, I’ll be fine
Sui: I’m not letting go! I am not going to sit and watch my savior give his life away!
Page 27
Sui: don’t go look for that guy!
Sui: don’t go….aahh…
Page 28
Sui: ahhhh!!!!
Sui: I couldn’t stop him! Damn it!
Sui: I was finally able to witness a true hero…
Sui: he shouldn’t have to die here!
Sui: from now on I’ll save as many people as I can…
Page 29
Page 30
Sui: this sound….it has begun!
Page 31
Page 32
Sui: silence…
Sui: ah….it’s over already!
Page 33
Page 34
Page 35
S: oh yes, I almost forgot to mention this: please keep my participation in the Superfight tournament a secret!
Page 36
Sui: O…Ok…
Sui: was Gouketsu strong?
S: eh…not really sure how he compares with the rest, all it took was one punch
Sui: I also have something I forgot to ask
S: What?
Page 37
Sui: I think I have to go into hiding
Sui: I’m badly hurt, and I don’t know how long it would take for me to overcome my fears, but…
Sui: I have found a goal for myself
Sui: can I become a hero?
S: no idea
Page 38
S: Before becoming overpowered, I suffered similar injuries like yours
S: of course, monsters were scary in the beginning
S: but since I’ve become a hero…
S: can’t everyone become a hero?
Sui: an overpowered hero…that sounds pretty good
Sui: can I ask you another question, Saitama kun?
Page 39
Sui: can I become your disciple?
S: I absolutely refuse
