Mechamaru couldn't fall asleep.
Everything in his body was hurting.
It will soon be his 16th birthday in this life, yet he was stuck here in this tub, while his friends would surprise his puppet on his birthday instead of him.
Even sighing hurt.
Why did he have to reincarnate as Mechamaru of all people!?
After falling from the 8th floor in his previous life, he reincarnated into the world of Jujutsu Kaisen as Kokichi Muta, aka Mechamaru.
Not only this world is really dangerous, he is reincarnated as Mechamaru of all people.
He was born without a right arm, and both of his legs are useless.
He has no feeling below his waist, his skin is so sensitive that it can't be touched by natural light.
The pores on his body always feel like they are being stabbed with needles.
In exchange of this ridiculous Heavenly Restriction, he can use his cursed technique over a vast range and output more cursed energy beyond his limits.
Still, it is more towards range than amount of cursed energy. He doesn't have cursed energy even at the level of Yuta for all this suffering he is enduring.
He has not committed suicide by now only because he knows that he can fix his body.
He has learnt Reverse Cursed Technique, but that didn't really do anything. This is his body's natural state. Healing will just bring it back to its natural state, not actually heal him.
There is still one option left.
Mahito.
He will feed Mahito to Yuta's Rika to copy Idle Transfiguration. Then have him master the technique and fix him.
He has eyes all over Japan, but so will Kenjaku when he gets Geto's bodies and gets countless cursed spirits under his control.
He has to find Mahito first, and to ensure that it isn't a race with Kenjaku, he will destroy Geto's body before Kenjaku can take it.
He controlled a Mechamaru to give him some pain killers and sleeping pills.
But before that could happen, he found himself in a strange room, on a round table.
Along with seven other equally confused people.
Some people who he recognised.
