"...A country to the east, of the rising sun, was for a time engulfed in darkness. To see the darkness of this world puts me in mind of that land. Son of man, thou dost wish to become the light to cut through darkness? I will measure thy strength!"

Shin Megami Tensei IV
Futotama is the client in the Challenge Quest, Resurrection of the Kousoushin. He resides in the Mejiji Shrine found in the Shinjuku region and receives a divination of Flynn's arrival, who is to be the hope of the Amatsu. Introducing himself as part of the ruling class of his race, he speaks of how they are being trampled upon by the demons who wish to take Tokyo away from the Amatsu and wishes for the freedom of Amaterasu in order to preserve their kind from facing extinction. Futotama mentions the three sacred treasures which will revive her. Once the three are collected he asks Flynn to offer the treasures at the Tokyo Castle Ruins, which lies north of Kasumigaseki.
Once Amaterasu is freed he suggests she leave for now in order to regain her strength so she can return and lead the Japanese gods in saving the barren land of Tokyo. Flynn obtains a portion of Futotama's power in the form of Torifune's Shawl so that he can fly.
Futotama can can be fused through a special fusion of Nue, Mishaguji and Tsuchigumo. He can teach Nanashi the Makarakarn skill through his Demon Whisper. Futotama has no skill affinities and does not benefit from learning any skills, however as a result he does not receive any penalties with certain affinities either.
