Souei/Abilities and Gear

He excels in spying and information gathering. By creating clones, he can get some sleep in shifts.

Though Rimuru taught him the basics of being a ninja, he developed it to suit his own tastes. The most important points were taught by Fuze.

Souei is currently studying torture. Souei can stimulate one's erogenous nerves with a thread. Rather than pain, a heavenly pleasure attacked them. In addition, he seals their ability to faint. If the target doesn't talk he or she will go mad.

Equipment
Souei received two ninjato forged by Kurobee from Demon Steel enriched with Rimuru's aura..

Souei does not wear armor. Instead, he wears chainmail woven from Rimuru's steel thread enriched with his aura, which was built for agility.

Souei also employs an iron thread imbued with Rimuru's power. The thread is connected to Rimuru at all times via his Time/Space technique and allows Souei to remain in constant contact in sort of an analog method. pt-br:Souei/Habilidades e Engrenagem
