Am I tripping or the omega os a minor? It doesn't seem right.

Well yeah in the beginning he was a minor but at the end he graduated and turned into an adult.
(Btw heard the japanese consent age is 16 and not 18 so it's basically not normal for us foreigners)

I get it now, thanks!

Oh but I'm not supporting whatever that shit is .
I genuinely read through the end by ignoring their age gap.
