Saitama and Genos's relationship unnaturalsolace: “ Alright, so I was just thinking about Genos and Saitama's relationship again like I do % of the day. What do you think?

So its unsurprising that after witnessing Saitama 'One Slapping' a monster with ease that he would beg Saitama to become his sensei. The goal being to become stronger.
