Ogre Trance

is a Noble Phantasm of Fuuma Kotarou.
By activating Ogre Trance, Kotarou can assume his true form, an oni or a being similair to it that resembles a foreigner. In this form, he gains acces to the Mad Enhancement Skill and his stamina is recovered every turn. As compensation, a portion of his being starts breaking down due to outputting his brain beyond its limits, resulting in severe damage to his internal organs and his lifespan shortening, among other drawbacks.Fate/Grand Order material IV - Fuma Kotaro, p.060-067
It is unavailable to him due to it being sealed, but Kotarou thinks studying oni could potentially allow him to release it.
