Why did Riezel want to learn jujutsu from Gojo Satoru?
It was because of his technique—the Limitless Cursed Technique.
Even by Riezel's standards, it was an outstanding technique.
At the very least, against opponents without spatial or temporal abilities, its effects could practically be called invincible.
If Riezel wanted to integrate the jujutsu system into his close-combat system, enhance his melee abilities, and make them comprehensively surpass his magic abilities, then acquiring the Limitless Cursed Technique was essential.
In this world, Gojo Satoru's Limitless Cursed Technique might not be the strongest, but it was certainly among the strongest. He couldn't go wrong with it.
The key to accomplishing this lay in the Modification Magic Lost Truth and the Memory Magic All-Rounder.
All-Rounder was magic that could perfectly reproduce magic stored in his memories. It allowed Riezel to learn nearly all magic and was the greatest key to forming his magic system.
Unfortunately, All-Rounder could only reproduce magic. That effect was clearly stated in his Ability Value, and it was completely useless for abilities outside of magic.
But the appearance of Lost Truth completely changed that situation.
While Lost Truth was active, Riezel could grant all of his magic the Aetherial Attribute, altering their effects and giving them other possibilities.
All-Rounder was no exception. It was magic that could be granted the Aetherial Attribute and modified by Lost Truth.
Just as Wind Spirit Sprint could transform into attributes other than wind after gaining the Aetherial Attribute, Riezel's All-Rounder, after gaining that attribute, also gained the possibility of reproducing abilities other than magic.
As long as Riezel activated Lost Truth while personally observing the target's effects, All-Rounder could memorize abilities other than magic during that time.
That way, abilities that met the conditions for reproduction could be used normally like magic, even
