Polymorphic Soul Isomer

Polymorphic Soul Isomer is an Idle Transfiguration technique.

Description
Utilizing Soul Multiplicity, the user can form the souls with weak rejection into one body. The result is a transfigured human that can attack the opponents on its own. A Polymorphic Soul Isomer is more stable than a regular transfigured human, as it doesn't seem to be capable of randomly dying mid-battle. A result of expending so many souls at once is the explosive power behind the Isomer's attacks, as they're strong enough to send a powerful sorcerer, like Aoi Todo, flying. However, the trade-off is the low durability of these transfigured humans, which was shown when Todo managed to take them down in just one punch for each.

Usage
Mahito used this technique first time during his confrontation against Yuji Itadori and Aoi Todo to force latter through a building and away from Yuji so that he can focus his attacks on Yuji only for the grade 1 student to quickly return.
