Séance Technique

Ogami copies the dead. Her technique channels a deceased person's physical body into a living vessel, transforming the vessel's appearance and physical attributes to match the dead person's. It copies the body only, no memories, no cursed technique, no personality.

The limitation sounds significant until you consider what happens when the copied body had extraordinary physical properties. A vessel channeling Toji Fushiguro'sToji FushiguroHumanThe Sorcerer Killer. Born into the Zenin clan with a Heavenly Restriction that traded every drop of cursed energy for a perfected physical body. Toji couldn't see curses, couldn't ... body gains Toji's Heavenly Restriction: the superhuman physique that traded all cursed energy for perfected physical ability.

Ogami used the technique during Shibuya, channeling Toji into her grandson. The result was a vessel with Toji's superhuman body, zero cursed energy, immeasurable physical strength and speed.

The technique then did something Ogami didn't anticipate: Toji's body was so physically dominant that it overwhelmed the grandson's identity entirely. Toji's combat instincts took over. The grandson effectively ceased to exist, replaced by a dead man's muscle memory piloting a remade body.

The hijacked Toji-vessel broke into Dagon's domain and killed the special grade cursed spirit bare-handed, without cursed energy, without technique, using nothing but the physical supremacy of a body that had been dead. Ogami's technique brought back something she couldn't control, and it accomplished more than she ever intended.
