[Reaper fanfic + no system + Soul Society suspense + wits against Aizen + original character portraits + not invincible]
Aizen Sosuke is dead.
The corpse was nailed to the high wall of the fifth division, and the entire Seireitei saw it.
The fourth division coroner, Kurose Kei, stood in front of the empty stone platform and heard Unohana Retsu ask him:
"Where is the fatal wound?"
Everyone is waiting for his answer.
But there was no body in front of him.
Kurose Kei then remembered that when Aizen demonstrated his Zanpakutō Kaikai many years ago, he missed the demonstration because he was dealing with a rotting Hollow.
That night, he was forced to write the autopsy report in front of the air.
The morgue door opened behind him.
The dead Aizen adjusted his glasses and stood in the darkness smiling.
"The report is well written."
From that day on, Kurose Kei must deceive three people at the same time.
Trick Aizen into believing that he has been hypnotized.
Deceive Soul Society and make everyone believe that Aizen is indeed dead.
He also deceives himself and pretends that every time he is silent, he is not exchanging the life of others for his own life.
