guys keep in mind that ao is a herbivore, he has a family, his family's used to handle this gang thingy with money because they NEED to keep the store. if even before asuka came they rebelled, they had nothing to back themselves with when the gang retaliate. that's why violence never solves things. because they can't do violence to begin with.
they have asuka now, but he's just an immature teenager, what can he even do?
hope the dad wont ruin everything. man didn't even get worried one bit when mom told him something's wrong with their son's school life. i don't care if he's regretting it now lol still doesn't justify the fact that he brushed the matter off.
