Firearm Usage: Tohyama Kinji is very knowledgeable and skilled in the usage of guns due to his education in Butei High. His skill with firearms is enhanced thirty-fold when under the influence of Hysteria Mode.
CQC (Close Quarters Combat): Kinji's hand-to-hand skills are fair, and only most formidable when under the influence of Hysteria Mode.
Hysteria Mode: The secret weapon of the Tohyama bloodline, the Hysteria Mode is a special genetic condition passed down to Kinji. Triggered by sexual arousal, the result is his brain and nerves get thirty times more efficient at everything it does. In short, Kinji's strength becomes thirty times that of his own as well as his reflexes, speed and intelligence. Hysteria Mode has allowed Kinji to perform inhuman feats of strength, speed and logic, such as deflecting bullets using his own bullets, performing a quick draw with his Beretta invisible to the naked eye, deflecting bullets with his fingers and performing an attack at supersonic speed. Also, Hysteria Mode's prerequisites allow him to seduce women with relative ease. His mannerisms and words are capable of flustering others of the opposite gender far too easily for his own good. His ace in the hole is not without its flaws - Hysteria mode prevents him from directly harming a woman, something that almost cost him his life against the Cao Cao triplets, and he remembers everything that happens in Hysteria mode so his Hysteria mode personality embarrasses him to no end.
Intellect: Despite his aloof and apathetic demeanor, Kinji is always watching and always listening to his surroundings. As a result, he can play the part of an apathetic bystander but is extremely clever and can easily exploit gaps in his opponents defenses. His calm personality also allows him to think under pressure, often allowing him to out think his opponent than outfight. To put it bluntly, Kinji was smart and sane enough to transfer to Inquesta, were he can slip out of the butei life to normal easily, learn more deductive traits and skills, and not get killed and harassed as much as he was in Assault. He must have subconsciously chosen the division that would not only make him stronger as a person and very clever, but also one that provides him more options for a normal life and meeting more people. Sadly, because of his apathy, people say that he should transfer back to Assault(Aria), and Sayonaki (a.k.a. Vlad), made a fool out of him because of it. However, this is another trick, as if people underestimate him, he can sucker-punch them easily and come out unsheathed as seen when he fought Jeanne, Vlad, KoKo, Hilda, and Watson. Watson also implied that he was difficult to fight because the information on Kinji was scarce, or unreliable. Meaning Kinji is capable of hiding long secrets, or his data is closely protected by the higher ups.
Social grace and empathy: Because of his experiences in middle school, Kinji both hates people and fear and avoid women going so far to call idiot or irrational monster respectively. But for all that bluster his kindness and understanding actually grant him strength. It gives him moral not be swayed seduction, drives to do his best and always be out there to things thru in the end. In fact he can charming and well if he wanted to, but is honest in his views of people to care and only comment on stupidity which wear him such as his friends, lovers, the Connect girls, and even allies. The added bonus is that he charm women easily on his own and only think he has to use Hysteria mode for seeing the result such use voice acting on Shirayuki to hypnotize using her love to his advantage. And posing as a butler, He even that has a talent for because the jerk to and everybody treats him like slave especially Aria.
Quadra Proficiency: Out of all of the Quadras introduced in the story, Kinji only has the title of Quadra when under the effects of Hysteria Mode. Because of this, he is easily one of the strongest Quadras because of his heightened abilities and has earned him the title of "Quadra of Mimicry."
