Susano'o/Biography

As one of the Sankishin, the Susano'o Unit has existed for as long as the Amaterasu and Tsukuyomi Units have. Eventually, the Unit began to grow a soul and recognised its own identity - this was the birth of Susano'o. He longed for freedom, to be free from the endless cycle of him destroying everything that Amaterasu would create so he could be his own individual.

To accomplish his goal, Susano'o allowed his body to be discovered by humanity as they salvaged him from the Boundary where he and his siblings had been resting. Through this, Amaterasu was discovered and the Prime Field War would soon ensue, but not before Susano'o's soul discarded the unit and became its own individual, Yuuki Terumi. Terumi inhabited the bodies of many vessels afterwards.

"Once one of the Six Heroes who defeated the Black Beast, as well as the one who plunged Ragna into despair, he may seem impulsive and shallow-sighted, but is actually quite crafty and clear-minded. Cold and cruel, he truly enjoys "despair" and "destruction" from the bottom of his heart, and starts the Imperator's even worse "banquet of madness.""

Story Mode
Terumi finally retrieved his body as Susano'o by using the Hihiirokane to shatter Hakumen’s soul. Susano'o effortlessly defeated Ragna the Bloodedge, Izayoi, Jubei, and Noel Vermillion, taking the latter outside of the Embryo and to the Gate alongside the Amaterasu Unit. He battled Es, calling her blasphemous for claiming the Gate to be the Azure’s holy grounds, as it was originally made for the Gods instead. He very nearly killed her, but she managed to escape at the last second.

Susano'o absorbed Noel, becoming immune to Phenomenon Intervention. He fought against both Ragna and Jin Kisaragi, but the former managed to rip Terumi out of the Unit. Terumi was dragged into the Gate and was killed by Ragna, thus ending the life of the God.
