Dr. Sato Amagai

Dr. Sato Amagai is a young human male who is credited with designing and building the REAPER model A.I. for ExoDUs. He serves as a support character in the game Project Reaper and is most noted for directing the player through missions and providing much of the plot dialogue in the first half of the game.

Amagai is intelligent, wise, and also understanding, making him the ideal mentor to the newly developed A.I.

Shortly after the A.I.s pilot mission, Amagai was introduced to Dr. Drenix Ironsigh, with whom he began to study the Angels with. During this time he contracted Umbral Toxin and became enthralled by its effects.

Seraphim had recognized the Reaper model A.I. as potentially being its equivalent and set out to destroy the mind that had created it. He used Amagai to stage an ambush on Reaper, forcing the A.I. to face one of the biggest moral dilemmas in cutting down its creator.

Ultimately Amagai was able to regain slight control and plead for Reaper's mercy killing. The A.I. reluctantly complied and granted Amagai peace. Afterwards Reaper set out to avenge its creator.

Amagai is seen in the final scene of the Good ending, seemingly having been reborn as a Galatian on Utopia. He makes a final appearance in the game Project ExoDus, in which his soul appears in a final state of tranquility.
