Profile
Shin Megami Tensei
In the beginning of the game, the protagonist has a dream featuring the Law Hero, Chaos Hero, Heroine, and Yuriko as well as an enigmatic prophecy of the future. The protagonist receives a computer that allows him to communicate with and summon demons from Stephen that he is able to use because of his special talents. While at the mall, he witnesses a demon kill a man, and is attacked by it as well. He is accused of this man's murder, and the protagonist is arrested and taken to a prison where he meets Law Hero for the first time. Later he encounters the Chaos Hero at the mall and the three of them, as well as the heroine, attempt to stop an ICBM missile attack from destroying Japan. Regardless of the choices the player makes, the party fails, and the Great Cataclysm occurs. The Heroine stays behind, but she manages to teleport the party into the Diamond Realm before the missiles hit. He later has the choice of helping the Messians complete the Basilica and having a world of peace, helping the Gaeans destroy it and giving the world freedom, or fighting both sides to make a world where there is balance and humans can decide their own fate.
He's given the name Sho in Shin Megami Tensei Final Story: Atlus Official Replay Novel, Kazuya in Shin Megami Tensei Character Profile: Steven Report I, and Futsuo in Kazuma Kaneko Complete Illustration Works. He is implied to be the reincarnation of Adam.
Shin Megami Tensei II
Before the events of Shin Megami Tensei II, the protagonist founded the Valhalla district of Tokyo Millennium and worked to help it expand alongside Cerberus and Madam. He refused to blindly obey the orders of the Center and was eventually killed in what was reported as an accidental cave-in. After his death, Madam took over as the governess of Valhalla and strove to continue his work.
During the game itself, a statue of the protagonist appears at the Colosseum, where it is labeled "First Champion". When seeing the statue before the first fight with Daleth, the statue will have tears flowing from its eyes for unknown reasons.
