Goro Akechi

Goro Akechi is the hidden main antagonist (and one of the playable characters) of video game, Persona 5.

Personality
Akechi is a great detective, being able to solve numerous cases and deal with people from the investigation agency smoothly. As a result, people called him "The Second Advent of the Detective Prince."

Despite his popularity, he is actually quite lonely and yearns to be loved. He was abandoned by his father, subsequently lost his mother to suicide, and never had any real friends.

He worked with his father, Masayoshi Shido, to gain acceptance, but at the same time secretly plotted to get revenge on him for abandoning him and his mother. He planned to ruin him while Shido is at the apex of his power.

After meeting and joining the party, he for the first time experiences how it feels to be happy together with friends, particularly the protagonist. Akechi both admires and envies him, since no matter his social standing and how others see him, the protagonist does not let anything stop him from making his own path. This made Akechi see the protagonist as the epitome of the very thing he could never have.
