for ones seen episode 10, here's my speculation.
Spoiler for spoiler, speculation:
is anyone speculating the entire student council to be in league with nerval or just that red haired girl who's was seen to be with nerval during episode 9(forgot her name)
personally i think it's only that girl, but since my chinese sucks, so i may misunderstand certain things, like whether the entire student council is in league with nerval or not.
with aleida reveal to be the same person as akiha's dream, think aleida's chance of being akiha's mother is a lot higher, with akiha being a bastard child that's adopted by the shishido
this is actually getting a lot more interesting since the plot moved instead of more excessive fan servicing
