Bnha react to ochako's brother is Chuuya || WORK IN PROGRESS || Part 2 || BSD x MHA crossover

AU explanation:

Chuuya's Uraraka's older brother, when he was about to turn 5,
he got kidnapped in the middle of the night
and when their parents saw that he disappeared when they woke up, they called the police
but after a few months of search without nothing, the police classed the case to become a cold case.

And their parents thought that he's dead,
this is why they never told uraraka that she had a brother.

Also, in this AU, quirk and ability are different. The only thing different is that abilities are extremely rare compared to quirk and are basically stronger than them.
You can difference abilities user than quirks because the developed before 4years.

And when their parents found out that he disappeared when they woke up they called the police.
Yokohama is sealed from japan when the quirks appear.
Nobody outside Yokohama can enter in except if their are allowed by the government.
