Kazura was selected as the winner on a lottery that he bought on a whim and received ¥4,000,000,000 (4 billion yen).

His muscles screamed, his body begged for rest, his mind ordered him to stop. But Bakugo couldn't. Not while Izuku hadn't arrived. So, he pushed forward. Every explosion, every strike, every movement was pure determination, a reflection of his unwavering will to win.For a moment, he felt beyond himself. Fast. Precise. Almost invincible.And then, in the blink of an eye, everything changed. The battlefield vanished, and the pain ceased.It was in that moment that Katsuki Bakugo understood... he had died.Disclaimer: I do not own any of the characters, images or songs featured in this fic.

From the age of 7, Qiao Qiao realised that her family wasn’t quite the same as her friends’ families.

Her father, dressed in all white, said, “Our girl should learn to cultivate immortality with me!”

Her mother, dressed in battle armor, said, “Our girl should train her body to protect herself!”

When discussing it, they decided to solve it with a duel outside.

Her brother secretly asked, “Qiao Qiao, do you want to be in the entertainment industry with me?”

Then, her brother was kicked out of the house by her parents. She prayed that he was okay out there. 

Qiao Qiao sighed. She was really worried about this family.

She silently collected mech building materials. There was no other way, if she learned how to use mechs, she would be able to get a good job. Unfortunately, her unreliable parents didn’t understand.

It seems like the burden of supporting this family was handed over to her.
