Everyone in Blind War was 16-19/20.
After they left they were around 17-20/21
When Peace Is Just As Blind started everyone was around 23-26.
Nakajima 'adopted' Yasuda when he was 6 and she was 14.
Nakajima is having the worst time possible and feeling the most amount of despair she can because Yasuda's in PIJAB and she watches it to see him.
Mitsuki's currently around the world competing in athletic things and hOpE.
Miona, Nakajima, and (kinda) Kaz stay together though Nakajima's constantly (silently) panicking.
Sakura travels with Mitsuki but films things and calls everyone thrice a week.
Narukami went back to working for Danganronpa but is only an official artist.
Shoi went back to work.
Hiromi has a very tiny place she creates theories and watches cartoons, like Gravity Falls.
/I'm listening to King by Lauren Aquilina and i find that it fits Nakajima well, also i'm tearing up idk why/
