A large part of the fandom misinterpreted this chapter. Kirishima wasn’t bullied, he was a failed bully buster. He was never shown being attacked first or maliciously ridiculed by his peers. Kirishima was first to use force here and those other children then responded in kind. Kirishima’s peers weren’t initially supportive of his dream but that doesn’t necessarily make them bullies.
So the middle school roles were thus:
Kirishima - failed bully buster
Mina - successful bully buster
Bakugou - bully
Izuku* - bully victim
*Child Izuku was both a bully victim and a failed bully buster. Some of the child Izuku bullying scenes were the result of him attempting to prevent Bakugou from bullying others. However, in the middle school scenes, all hostilities were initiated against Izuku directly.
