I'm a hero for fun, not a father

Becoming heroes

Saitama, Genos and the kids were all outside a giant building, which was the place for people to become heroes. the four were about to walk in when they heard a familiar voice.

"I see you guys came," zombieman said walking up to them.

"well yeah I need to since I've been doing this hero business for three years now," saitama said.

"master we better get going the exam going to start," genos said when he checked the time.

" well you guys get going, I will be watching." zombieman said before heading towards the viewing area.

the four entered the building but genos had to participate in the other part of the building so Saitama and the kids had to go together as the kids wouldn't leave their father's side. they got into the changing rooms with saitama having to help the kids with their change of clothes.

meanwhile outside the building-

"come on big brother it's starting and I want to see the new upcoming heroes!" a little girl was shouting at her big brother telling him to hurry up

"I don't know why you want to see new heroes tenko?" the older brother said.

heading towards the building was a little girl named zenko who had short hair with a flower pin in it and was wearing a white dress, her older brother was non-other than the 17-year-old meathead metal bat who is an S-class hero, metal bat didn't want to come to this to see the new hero as today was his off day so he wanted to spend time with his sister, but his sister wanted to see how the test are like so she can become a hero as well, since the day her brother became a hero she also wanted to become one.

so she would keep on demanding Bad, (metal bats' real name) take her to some of the strongest female heroes like captain Mizuki or tank top girl so she can also be a hero but he would always say no, this is the only time he would say no to her as he was a very overprotective brother. and that he didn't want to see her get hurt, after all since their parents are always busy and never have time for them, Metal bat is the one looking after her.

they finally entered the building and went to the viewing area, while looking for a seat metal bat saw Zombieman also there. this confused the meathead boy so he went over and started talking to the undead hero.

"Zombieman?" Metal bat said his name.

Zombieman turned and saw Metal bat with his sister.

"oh Metal bat, what are you doing here?" Zombie man asked

"I could be asking you the same thing?" Metal bat said

Zombieman was about answer Metal bat when they were interrupted by the sounds of two kids.

"Mr Zombie man!" both aisuru and buru shouted.

"Oh, you two done already?" Zombie man asked the kids.

"yeah, they decided to only make us do half as we are only kids," Aisuru said to the undead hero.

metal bat and zenko were caught off guard, two kids came up to Zombie man and started talking to him like it was normal, even though he was an S-class hero, but what caught both of their attention was that the kids had monster features, the little girl had two horns coming out of her head, and the boy looked like a dragon-human hybrid.

"um, Zombie man who are they?" Metal bat asked

"Oh, these two are the kids of a friend that's also taking the hero entrance exam." Zombie man said

the kids looked at the siblings, confused about who they were.

"Kids this is Metal bat an S-class hero like me and that's his little sister." Zombie man said to the kids
