Index: Volume 1
1 Punch: Omega (or Saitama really should have changed the locks; Omegaverse with Omega!Saitama) NSFW
It also didn't help that the cyborg had gone stock-still after releasing a noise reminiscent of a circuit breaker blowing a fuse. And with Genos just standing there, slack-jawed, mouth hanging wide open, and eyes practically flashing error messages, the only reasonable thing Saitama could do was this: absolutely freak. "For the love of god, this isn't a free show! GET THE FUCK OUT!"
2 Punch: Alpha (or Genos wants what he can't have; Alpha!Genos)
Saitama was strong: the personification of absolute control and power. Omega or not, he didn't need anyone— didn't want anyone. Let alone a defective alpha like Genos.
3 Punch: Take the Lead (or why Saitama can't give what he doesn't have)
"You should— you deserveto know why." Of what an empty heart can be, a dull metronome that only keeps time and never plays in tune.
4 Punch: Flick of the Wrist (or an HP!AU with Hufflepuff!Saitama and Durmstrang!Genos set during the Triwizard Tournament [and the Yule Ball])
"Will you accompany me to the Yule Ball?" "Eh? Oh sure..." By the time the question registered in his mind, Saitama found himself spewing his drink all over King's hand-knit Christmas sweater. "You know, you should really think before you speak," King muttered dryly, tone a complete contrast to his damp wardrobe. He shot a glance at the retreating figure of the strange blond who had just (successfully?) courted his friend.
5 Punch: Reversal (or an AU where Genos is the 25 y.o. Hero alongside his reluctant disciple, 19 y.o. Saitama; Saitama is still OP but Genos has absolutely no idea)
"So, you want to be a hero?" "Well yeah. For a hobby, I guess." Golden eyes narrowed at the slight boy before him, unruly mop of black strands and eyes that belied a hollowness one would associate more with a middle-aged man undergoing a midlife crisis rather than a teenager at the cusp of adulthood. But still...the boy had potential. And as far as Genos saw, the boy had no one else to turn to. "I see...to undertake such a goal, you need proper guidance. Very well...I accept responsibility." "Eh? That's not really nece— " "Do not worry; it's of no burden to me. It is the least I can do after the damage that befell your apartment. And from now on, please refer to me as 'Sensei.'" "Weren't you just listening?!"
6 Punch: Missing Pieces (or Genos recruits the help of his friends to find something very important) NSFW-ish
"I'm glad you all came at such short notice." "Whatever. You better make this quick, you hear me?" "It's certainly unusual for you to call on us." "Especially without Saitama." "Where is he anyways? It's actually pretty rare to see you two without each other nowadays." "It seems like a serious matter...should we find him?" At that, something akin to a trigger set of an alarm in Genos's mind."Sensei cannot know about this! Absolutely not!" "...why?" After gathering himself for a moment, Genos turned to them, face uncharacteristically expressive and unnervingly miserable. "Because...I'm here to ask you all...to help me look for my wedding ring."
