From the Ultra Age Fanbook Released today
Question: Did Ochako finally confess her feelings to Deku?
Horikoshi: Please read Manga Volume 42 and use your own imagination for that answer.
Question: Tsuyu's room is said to have a bit of 'ethnic vibes.' What kind of decorations does she have?
Horikoshi: I wouldn't call it 'ethnic' per se, but she has a lot of plants and moss, kind of like a paludarium.
Question: What degree is Iida's eyesight? He doesn't wear glasses when wearing his hero suit, so does he use contacts instead?
Horikoshi: His eyesight is -0.8. When he's wearing his costume, his helmet has built in prescription lenses.
Question: Do Class A students know about Kirishima's "High School Debut"?
Horikoshi: Yes they do. He actually talked about it after the second battle in the Final War arc. He even openly talks about it with media after going Pro as well. It's briefly touched upon in Chapter 430
Question: Even though Jirou is a Pro-Hero, does she still pursue music?
Horikoshi: Yes, she does. When she's not doing Pro-Hero work, she finds time to do music related work. It seems like she even teaches Eri guitar or bass when she has time on her days off!
Question: In the last chapter, Shinso has long hair. Did he grow it out because he looks up to Aizawa?
Horikoshi: Yes, it's out of respect for Aizawa. Actually, in Volume 34, I wanted to show his long hair already, but the pose I drew had him upside down, so it was unclear.
Question: Has Dark Shadow always been with Tokoyami since he was a child?
Horikoshi: They've always been together. When he was younger, he had to keep the lights slightly on to not rile up Dark Shadow. He would apologize to Dark Shadow by saying "good night, sorry it's kinda bright" and Dark Shadow would respond "g'nite, no worries!"
