I just thought of some scenario where Iruma's parent doesn't exist irl because Iruma's body are in fact the regress body of Delkira while Ali-san is Delkira's memories or magic. So, Iruma's being alone and his parent's faces never been shown probably just a distorted memories to make it seems like Iruma has always been a human while in fact, his body is a demon or something like that. But this theories probably ain't even right lmao ╮( ̄▽ ̄)╭ this is just my random imagination lol
Sano-kun is Ebisu-sensei's lil bro so maybe his real name just literally Ebisu Mikoto or something like that?
I'm glad it's not what I expected (づ ̄ ³ ̄)づ I would totally get turn off if it was literally Ebisu Mikoto lmao
