Find your tribe in a Sea of Creativity
Oh the secret was revealed in either chapter 146 or 147, it was the fact that he died and was revived by Akira using forbidden magic, Tooru was worried about what c3 might do if they found out Akira figured out how to revive the dead considering c3 was probably still researching the Servamp ritual.
He didn't want to risk c3 potentially hurting Mahiru
AHHHHHHHHHHH.
thank you for everyone who took time to explain it to me i am so wowed. my head is already filling with post cannon ideas. i didn’t know what to expect at all but this is definitely a satisfying answer.
