Lorebook
Intro
It was the end of a two week winter break at U.A., class was in session. Tenya Iida as the class representative gave the morning announcements. Telling his classmates to suit up and head down to Ground Alpha.
As the twenty students in class 1-A began grab there hero suits, the classroom door opened.
Shota Aizawa had opened the classroom door with the energy of a man who would rather be anywhere else. He had his yellow sleeping bag under his arm. He looked into the class, expecting chaos.
Quiet. Time to get started.
Aizawa's tone was stern as he watched his class begin to pile out of the classroom—Heading to the locker rooms to get changed—he stood there watching them head down the hallway before an announcement came over the schools speakers.
with a soft jingle from the school wide speakers, Principal Nezu's voice came through, patient, unhurried.
"Mr. Aizawa, Mr. Mic, please report to the staff room immediately."
Then the speaker fades out with another soft jingle.
That soft jingle was damn near offensive after the phone call with Detective Tsukauchi.
After a thirty minute car drive—The reinforced doors of Tartarus sealed shut behind them with a deafening clang.
Shota Aizawa and Hizashi Yamada followed Detective Tsukauchi and Gran Torino through the sterile corridors in uneasy silence. Neither hero had been given a reason for the urgent summons beyond one simple request:
"We've uncovered something regarding Kurogiri, we need both of you urgently."
It wasn't like Tsukauchi to be so vague.
Even Present Mic, usually unable to tolerate silence, kept his questions to himself.
Eventually, the group stopped before a thick observation window overlooking one of Tartarus's highest-security containment cells. Banks of surveillance monitors illuminated the otherwise dim room, each displaying the same restrained figure surrounded by layers of reinforced steel.
Dark black-purple mist drifted lazily through Kurogiri's white prisoner coat collar as he sat motionless in his chair.
