In his battle against Szayelaaporro Granz, Mayuri enunciated the primary role of a scientist. He explained that men of science must chase after perfection, but it is out of reach.

The blonde-haired devil even manipulates his grandparents and becomes an authoritarian figure in their rural neighborhood. 

Kusuke is one of the few individuals unaffected by Teruhashi’s beauty. He was repulsed by Kokomi and deemed her puny and unworthy of Kusuo. This incident shows that Kusuke doesn’t lose his mind around gorgeous girls and stays sharp. 

Meticulous and sadistic, Kusuke enjoys putting his brother in dangerous situations. A cunning super-genius, Kusuke has found a way to block Kusuo’s powers; thus, the MC cannot read his mind. He helped create the control devices, which helped Kusuo have better control over his powers.

Anime: Kiseijuu- Parasyte Maxim
IQ Level: 220+

From that point onwards, Migi tries his best to safeguard Shinichi’s existence by collaborating with the human host and coming up with schemes to deal with opponents. 

Migi is aptly named after the direction “right” since he dwells within Izumi’s right arm. He believes humans resemble demons, as they frequently exploit and exhaust natural resources. Because he is incapable of experiencing human emotions, Migi uses logic and analytical reasoning to annihilate enemies. 

Naturally curious, Migi adapted to human life by reading dozens of books at Shinichi’s house. He isn’t completely devoid of attachment, as he established a great bond with Izumi, which was visible in the final episode of the series. A shrewd and calculating parasite, he is why Shinichi survived multiple fights against overwhelmingly powerful adversaries.

Saiki manages to get average scores to avoid attention from his classmates. He is blessed with many broken abilities like psychometry, clairvoyance, mentalism, etc., which allows him to outsmart all his enemies, and sometimes his relentless friends. The man with the antenna always has a solution ready when facing a problem. 

Saiki is constantly trying to prevent mayhem and chaos from spreading. He cares deeply about the well-being of his pals but rarely shows his considerate side. The pink-haired tsundere is a certified genius.
