During Junpei’s school fight, Mahito tried using Tasteless Transformation on Yuji but strangely it didn’t work. Therefore, he chose to attack the young man directly.
But why the technique of Mahito no effect on Yuji?
1. Upon feeling the impact of Yuji’s punch, Mahito doubted that Yuji could understand the state of the soul because of his experience as Sukuna’s vessel
First time, Mahito always fight confidently because no matter how injured he is by the enemy’s attack, thanks to the Tasteless Transformation, he can still recover. However, Mahito discovers that there is a natural enemy that prevents him from moving carelessly, which is Yuji.
Initial, Mahito believes that Yuji’s attack is useless but then he begins to bleed. Mahito conjectures that Yuji is able to perceive the soul by sharing a body with Sukuna. When hit by Yuji’s fist, Mahito I felt like my body and soul were really hurt by that attack.
2. Sukuna – someone who is far beyond Mahito’s level does not like having his soul touched by others
In addition to Yuji’s ability to directly sense the state of his soul Mahito , there is also an external factor that prevents him from being affected by the Tasteless Change. That’s thanks to Sukuna living inside Yuji’s body. The curse king doesn’t like his engineering Mahito touched his soul, so he threatened Mahito for this action.
For Mahito his strength compared to Sukuna is like earth and sky. Mahito once almost lost his life because he violated Sukuna’s warning not to touch his soul a second time.
3. It will only be safe if Mahito uses territory expansion to attack Yuji without Sukuna intervening
Because he knew Sukuna didn’t want his soul to be touched Mahito had words with Sukuna immediately upon activating his spell during his battle with Yuji in Shibuya.
At the time of opening the territory, Mahito met Sukuna again in Yuji’s subconscious and said that he would finish Yuji when he was sure the Curse King had reached some kind of agreement with Yuji. He won’t let that happen so Sukuna just stay there and watch.
Hearing that, Sukuna did not show any reaction but let it go Mahito fight Yuji until the end. Hence, Mahito escaped Sukuna’s punishment.
