In the Z-City's ghost town in the apartment we see Genos at y/n and Saitama's apartment as Genos said
Genos: Teachers!!
She said and also did I mentioned she requested y/n and Saitama be her teacher which y/n agrees and Saitama refuses but Genos automatically becomes his student. As Saitama opens the door and said
Saitama: you actually came... Err what's your name again?
Genos: it's genos Teacher Saitama!!
Saitama: ...Sorry, but could you stop calling me teacher?
Genos: Master!!
(I swear this shit gets SUS as Fuck)
Saitama: Don't call me that either I swear if dad hears this he might get the wrong idea
As Saitama let's genos in and we see in the apartment mosquito girl drinking a pack of blood and y/n making some tea 🍵As both Saitama and Genos sit as y/n serves them as tea
Saitama: Go home when you're done drinking I'm not looking for Disciples, mind you...
Y/n: don't be rude Saitama
Saitama: sure dad... Huh? You're in one piece again
Genos: yes since my body is mostly artificial, it's easy to repair if there are spare parts
Y/n: well that's interesting
Saitama: you're weird you know that?
Genos: teacher, what artificial part do you use?
Saitama: I don't use any
Genos: Eh? Then what's that skin-colored armor on your head?
Saitama: it's called skin
As Genos just roast him
Genos: But that would mean that you're already bald even though you're still young and master y/n is your dad but is older than you and he still looks like a teen...
Saitama: So what if I'm bald!? What the fuck is your problem anyways!? And the reason why dad looks young is because he is-
Y/n: Saitama be kind to our guest
Saitama: S-sorry
Genos: my problem? Will you hear me out, teachers
Saitama: Uh, no, thanks
Y/n: sure I would like to hear you out
Genos: It all started 4 years ago... I was 15 years old and still a normal human being. Even in this harsh world, I had a pretty happy and peaceful life with my family until then. But one day, a crazy cyborg attacked our town all of a sudden he had completely lost his mind... I guess, his brain had been damage during it's transplantation into his cyborg body. He left after destroying every single thing in town. The parks, The schools, The buildings, My home... If course my family didn't survive. Only I miraculously spared, but I was just a meek 15-year-old girl back then, I wouldn't have survived long all alone in the ruins of a town if Dr. Stench hadn't found me passed town by chance and found me. Dr. Stench is a scientist of justice and was pursuing the cyborg to stop him.i begged Dr. Stench to transform me into a cyborg and was reborn as a cyborg who fights for justice. I made a promise to Dr. Stench to find that cyborg one day and destroy him.
You thought it was over noo it is not
Genos: 4 years have passed since then I'm 19 years old now and I've been travelling from town to town fighting of evil on the way. I have defeated countless monster and evil organization... But unable to find any clues on the whereabouts of the mad cyborg, I couldn't help but feel more and more irritated and restless by the day. I have spent the last 4 years chasing after the cyborg without success. And then a week ago... When that mosquito monster over there drinking your father's blood appeared, I really let my guard down. It's because I was convinced that I couldn't possibly lose to anyone that isn't that mad cyborg. I made a full-frontal attack without even performing a data analysis on her beforehand. You already know what happened after that. I was caught off guard by her hidden powers and I could and I would definitely been destroyed if you and your father hadn't passed by, by the chance. Your father save my life and your father the and now it feels like the weight on my shoulder doubled. Now that it's come to this, I absolutely can't die before I've destroyed that cyborg. And for that I'll have to continue fighting evil until he appears before me one day. ... I have to become stronger! When I say your father easily stop mosquito girl last week, I knew I had to become both your father and you disciple since you are his son you must be strong like him. If I was strong as you and your father... Teacher Saitama and teacher y/n, I must destroy that cyborg! And it's not only for myself. It's also for my hometown and for Dr. Stench room I know I'm still inexperienced... But I'm prepared to do anything to attain the power I need to defeat evil!
