After losing a leg and an eye at Jaku, Aizawa Shouta spends three months in the hospital; it's the big damn Eraserhead recovery fic.
Spoilers beyond Chapter 282 / S6E9
Part 1 of Lullabies for Insomniacs
With his husband out of town, his friends all busy, the school term over, and all his work either dried up or completely done, twenty-nine year-old Aizawa Shouta finds himself incredibly bored. As most bored pro heroes do, Shouta looks for a case to solve and comes across that of a man terrorizing children in a district near where Shouta grew up.
Investigating leads Shouta to a forum for underground heroes that particularly focuses on his hero persona, and then to a specific person, a fourteen year-old kid who goes by the screen-name 'Mindjack', who is Eraserhead's biggest fan and happens to live in the district where Shouta's villain is.
Late night chats lead to Shouta getting attached to this kid and slowly becoming more and more intent on taking down the villain threatening his neighborhood.
Aizawa had never been given a choice. Decried as a villain, publicly revealed as a traitor to his own heroic ideals, his fall is engineered perfectly to maximise his chances of being picked up by the villainous group Basilisk. Deep undercover, his goal is to uncover the human trafficking operations and their newest cargo – pro heroes.
"If you're looking for Midnight-sensei, she already left." Shinsou Hitoshi spoke softly, couldn't keep eye contact, and looked like he was a few seconds away from collapsing into an exhausted pile caused by copious amounts of stress.
"No. You're Shinsou Hitoshi." Shouta didn't bother to phrase it as a question, but he was curious when the kid tensed as if expecting a fight or a scolding. "Do you know who I am?"
Shinsou glanced around as if expecting a trick, the kid finally meeting his eyes for a quick moment, "You're Eraserhead." Huh. Kid knew his heroes, then. "And you're here to tell me what I'm in trouble for."
"Who says you're in trouble?" Shouta had seen Shinsou's school file and it certainly hadn't been light, but considering his quirk and background, he wouldn't be surprised if more than half of those 'fights' had been started by others and then blamed on him.
"Because you're a teacher for the hero course, sir, and the only reason for a teacher from Class 1-A to be talking to me is if I'm in trouble." What a depressing and sarcastically polite kid.
"Do you still want to be a hero?"
