"This is the operation that our researchers...no, humanity's pleas! I wish all subjects of this experiment realize their own happiness! IF I completed the Jail system, humanity shall be freed from their pain! Come, let us toast! For this great operation, and the glory of humanity! With the power of EMMA, this shall be fulfilled!"
Shuzo Ubukata is a minor character in Persona 5 Strikers.
Ubukata is a well-known AI genius hailing from Okinawa. After Akira Konoe loaned the EMMA app to a research lab in Okinawa in order to have it develop knowledge of cognitive psience, it created the first Jail, turning its citizens into fervent believers of God by stealing their hearts. Ubukata, now being a Jail's Monarch and a pawn for a higher power, was driven insane when he was told to "hand out the desires he kept" by this power (presumably Konoe) and committed suicide by jumping off a cliff. His death was later used by Akira Konoe as an excuse to capture the Phantom Thieves so he can be the sole hero of this world.
Ubukata's sin was sloth, referencing how he chose to commit suicide as a way out when he was used by Konoe and told by him to hand out his desires.
