Ultimately, the emotion of despair, uncontrollably surged from the depths of Nanami's heart, wildly crushing his sanity.
Nanami could no longer control his thoughts, as his mind could hold nothing but fear and despair.
The body's instinct for self-preservation took over, spontaneously controlling Nanami's body to rush towards the depths of the sewer not blocked by Mahito.
But after Mahito extended his arm again and attacked, directly severing Nanami's legs, even moving became a luxury.
Mahito looked at Nanami, who had lost his legs and was barely crawling with his severed left arm. After confirming that he had no ability to escape his control or contact Gojo Satoru, Mahito began to search the surroundings.
What Mahito was looking for was something that could be used as a weapon and contained no Cursed Energy, to deliver the final blow to Nanami.
"Bear with it a little longer, okay? I can't kill you with Cursed Energy. Let me find something good to finish you off, hmm... how about this?"
Mahito said, tearing a metal rod from a drainpipe, and slowly walked over to Nanami, stepping on Nanami's back to stop his crawling.
"Sleep well. When you wake up, we'll be the same kind."
Mahito said, and directly plunged the metal rod into Nanami's brain.
After a while, Mahito reached out to check the state of Nanami's soul, confirming that the human Jujutsu Sorcerer Kento Nanami was completely dead. He then pulled out the metal rod and threw it into a deep pipe nearby.
Then, he controlled his right hand to partially transform into Idle Transfiguration, crushing Nanami's head to create the illusion that Nanami died from his Cursed Technique.
As for why he did this, it was, of course, to prevent Kenjaku from noticing the plan he was carrying out.
It was at this time that Kenjaku, dressed in pure black clothes, also arrived in the sewer.
"You've made quite a commotion, haven't you?" Kenjaku said, slowly walking over to Mahito.
Kenjaku came for two main reasons. On one hand, Mahito had informed him that he wanted to create a dangerous situation for Itadori to allow Sukuna to use it as leverage to establish a more convenient binding vow and deal.
Although Kenjaku had other arrangements for Itadori and Sukuna, if it was for this purpose, he naturally had no reason to refuse, so he came along to check the situation.
But compared to this reason, the other reason was the primary cause for his appearance.
Kenjaku needed to confirm the growth of Mahito's Cursed Technique accuracy, as Mahito (Idle Transfiguration) was the most crucial gear in his Culling Game plan.
At the same time, Kenjaku also had to ensure that Mahito wouldn't be discovered and directly eliminated by Gojo Satoru due to making too much of a commotion, a terrible development.
But when Kenjaku saw Nanami's horrific death, felt the strong Cursed Energy residue on Mahito's hand, and then recalled the scattered limbs on the ground and Mahito's body, which had no obvious injuries, a question arose in his mind: Was Mahito's combat level really that high?
Leaving aside the Cursed Technique factor, among the Four Great Calamities, Jogo was undoubtedly the strongest. A Cursed Spirit like Mahito, who hadn't been born for long, naturally couldn't compare to Jogo, who had relatively rich combat experience. Coupled with Gojo Satoru single-handedly suppressing all Cursed Spirits, Mahito's actual combat encounters with stronger Jujutsu Sorcerers should be very few.
Could Mahito, with such experience, really be so decisive and clean?
Kento Nanami was certainly not a top-tier Jujutsu Sorcerer to Kenjaku, but the effect of his Cursed Technique was still remarkable. Essentially, as long as he could hit the target, regardless of the opponent's strength, even Kenjaku himself would suffer some damage if hit.
That Nanami was single-handedly killed by Mahito without injury indeed exceeded Kenjaku's expectations.
Could there have been a breakthrough in his Cursed Technique?
Kenjaku thought for a moment, finding no clues for an answer, so he simply asked directly.
"It seems the battle was quite easy, wasn't it?"
Mahito looked at Kenjaku's expression and, combining it with his words, could basically confirm that the other party had not discovered his non-Cursed Technique killing of Nanami.
After all, Kenjaku's body was that of the Jujutsu Sorcerer Suguru Geto, not a dog, so it was impossible for him to detect the metal rod which had no Cursed Spirit reaction.
Mahito, while wiping off the mixture of blood and brain matter from his hand, smiled and spoke to Kenjaku.
"You're here, Geto. Indeed, Jujutsu Sorcerers are much weaker than imagined. Now, the only one we need to worry about is Gojo Satoru, right?"
"It seems you are more talented than I thought. Perhaps your plan can also proceed smoothly."
"If nothing goes wrong, that child should be on his way to bring Itadori Yuji here. Are you going to stay here?"
"Your purpose in killing this Jujutsu Sorcerer is to enrage Itadori, then suppress him through battle, making him cry out to Sukuna for help to establish a powerful contract, right?" Kenjaku roughly understood what Mahito wanted to do.
"Some well-timed despair is always needed to stimulate him into a state mixed with anger and sadness. In such a state, his rationality will be greatly reduced, which is more suitable for our plan, isn't it?"
"That's true, but if he exchanges Sukuna out, I can't guarantee that Sukuna won't attack you because of his promise with Itadori," Kenjaku 'kindly' reminded.
Both of them simultaneously heard Itadori's shout from outside.
"Wait, we're not bad guys!"
Apparently, he was telling Yoshino Junpei, whose body was controlled by Mahito, to stop.
Although only Itadori and Seto, a non-Jujutsu High assistant officer, had arrived, Kenjaku decided to leave to be safe. Mahito called out to Kenjaku, who was heading deeper to leave.
"Hey Geto, you still have Sukuna's Fingers, right?"
"What's wrong?"
"Give me one. If things get too bad, if I hand over the finger, Sukuna should let me go, right?" Mahito said to Kenjaku, half-jokingly.
Kenjaku thought for a moment. The fingers were originally meant for Itadori to absorb, so he took a Sukuna's Finger from his pocket and tossed it over.
Mahito toyed with the Sukuna's Finger in his hand. Kenjaku was more straightforward than he had imagined.
When Kenjaku turned around again, Mahito called out to him once more.
"Since you're leaving anyway, help me deal with the tag-along (assistant officer) behind Itadori. You wouldn't want Gojo Satoru to appear now, would you?"
