However, one night when the two were chasing down a Shadow, Shinjiro’s Persona went out of control and an innocent bystander was killed. The bystander was Ken Amada’s mother.
After the incident, Shinjiro left SEES and his friendship with Akihiko became strained. The two only reconnect when Ken joins SEES, and Akihiko convinces Shinjiro to rejoin the group in order to protect him.
When Akihiko realizes that Ken only volunteered for SEES as a means to get revenge on Shinjiro, he tries to save both of them from making grave mistakes, but he arrives too late. Though Ken lets go of his vendetta, Shinjiro is fatally shot while protecting him from Takaya.

Akihiko is determined that Shinjiro’s death not be in vain and to be just as fearless in the face of his own mortality. He is the character that is the least upset and conflicted about the impossible odds of fighting Nyx.
