Juuzou's class and Akira's age also conflict with each other (they should be classmates, Juuzou's profile states his class is the 72nd one, however Akira's age suggests that she should be in the 73rd one).

I talked about this with Haro. For now, we have decided not to fix it, but have noted it on Tokyo Ghoul Wiki:Character ages and investigator classes.

For this reason, I will also not derive Seidou's birth year and age from the class, though he's obviously born in the same year as Akira.
