Character Profile— 

Original Name— Adrian Frost

Current Name— Yamamoto Tatsuya 

Height— 6'2 

Weight— 90kgs

Personality— 

Appeared to be a simple deranged pervert at the start of the book but slowly revealed himself to be a sociopath that revels in pleasure by destroying people emotionally and mentally. 

At the start of the book he was unaware if the System would allow him to move to different worlds so he restrained his desires and acted as a kind, polite and charismatic individual as social image was a powerful tool.

But after he Blackmailed Airi Sakura for sex his System informed him of his main mission and that he could leave the world after fucking five main female characters. 

After confirming this Tatsuya slowly lets go of the persona he created and begins to act like his true self. 

He ruled the class by fear and mercilessly expelled three students from the class. Gave hope to the class that they could save those students only for him to crush that hope again. 

It is also later revealed that Tatsuya was incapable of feeling true love for anyone besides himself. He could sacrifice whoever needed to ensure his own life. It is also stated that before he was reincarnated in his original world on Earth he used the death of his sister to emotionally manipulate his mother for sexual favors, unfortunately never could have sex with her and she too died in an accident.

He remained a virgin as he found normal girls and relationships boring and fantasized fucking Jade Beauties from Xianxia till the System killed him and brought him to Classroom of the Elite.

Beneath his perverted tendencies lies a cunning and manipulative man that will plan steps ahead to make sure he's always in the benefit.

Trusts no one but himself, not even the System.

Ps. Has no bottom line.
