Akinari Kamiki
Akinari Kamiki (神木 秋成, Kamiki Akinari?) is a dying young man who writes to ease his mind. Through the Protagonist' interaction with Akinari, he helps him in understanding his purpose in life and helps him to overcome his grief of his disease. Upon maximizing the Social Link, Akinari gives the Protagonist his finished book to be published—and disappears before his startled eyes.
In Persona 4, Kanji Tatsumi makes a reference to Akinari's book, revealing that it was indeed published.
Akinari is the Social Link for the Sun Arcana (太陽, Taiyō?), representing a bright future and a true achievement, and is only encountered during Maiko's Social Link.
