Kinji Tohyama

Kinji Tohyama is the main male protagonist, anti-hero and narrator of the light novel and anime series Aria the Scarlet Ammo. He is an E Rank Butei who comes from a family of legendary heroes. However, Kinji wants nothing to do with his family's legacy, and has desired to live a normal life since the death of his brother. One day, however, he is saved by a girl named Aria H. Kanzaki, a descendant of Sherlock Holmes himself, and reluctantly becomes her partner shortly afterwards.

He is voiced by Junji Majima in the Japanese version of the anime and Todd Haberkorn in the English version, the former of whom also voices Ryuuji Takasu and Ayumu Aikawa.

Appearance
Kinji is a young man of average height with wavy black hair and brown eyes. He has been described as handsome and gloomy. Throughout most of the series, he wears his Butei High School uniform.

Personality
Due to the apparent death of his older brother Kinichi as well as the ridicule he suffered afterwards, Kinji is a very bitter, cynical and sarcastic young man who rarely has a good word to say about anybody. Before meeting Aria, he wanted nothing more than to quit his life as a Butei and live a normal life, believing his life doesn't have to be special just because he comes from a famous family. However, Aria accuses him of simply running away and being scared of his true potential, and he eventually agrees to become her partner, albeit reluctantly. He almost never smiles, and when he does it's usually his way of acting like nothing suspicious is going on, and therefore hardly ever sincere.

Kinji's personality under the influence of Hysteria Savant Syndrome takes a dramatic shift by becoming unnecessarily melodramatic when it comes to his statements and speaks with a smooth demeanor and indifference to women shifts into a seductive manner, causing him to go to great lengths to protect them both physically and mentally. This has caused women to become seduced and sometimes faint. However, when he is under the influence of Hysteria Berserk, all of his bottled up feelings including rage are released and set free. Kinji is able to remember everything he said while in Hysteria Mode, and gets really embarrassed whenever he looks back on it.

On the outside, Kinji appears to be highly anti-social to most people and especially cold to women, even borderline misogynistic due to trauma with girls during middle school, where he was taken advantage of and being ganged up when trying to stand up for himself. He has zero tolerance for Aria's bossy, immature behaviour and before long begins to despise her, though he gets over this after learning her true motives. He isn't even particularly nice to Shirayuki, whom he's known since both of them were children. To his classmates, he's often thought as a loser, shut-in, womanizer, and a waste of talent because of his indifferent attitude to the point of feeling isolated among the student body. He's even believed to be homosexual since he shows little to no interest in women.

Despite all this, Kinji is deep down a kind and caring person with a strong sense of justice as a Tohyama, even though he hates it. He believes the powerful should not harass those without power and follow the rules of law even if his life is at risk for the sake of order. This includes taking opponent even more powerful than him like Jeanne, Kinichi (Kana), Patra, Sherlock, Watson, Hilda, and GIII. Kinji to the dismay of Aria, prefers to a non-violent approach when facing the enemy before attacking. Also, as noted by Aria, Kinji will show world-class bravery in the face of great danger. In addition, Kinji will not hold a grudge against anyone for their past actions because he believes it is a waste of time and he has learned to forget about it.

For for all attitude about hating people and being a misogynist, Kinji also deeply values his friends and family to the point of going to great lengths to protect them even if he has to enter Hysteria Mode. More importantly, he has a rather subtle charm that draws people towards him including giving off an aura similar to a great leader as observed by Reki and Tsuzuri. This has caused the entirety of the Assault department, including Akari Mamiya (who's jealous of him), to secretly worship and respect him. In addition, he believes that as man he should protect women even though he is not always successful at it.
