The Tohyama Household (遠山家 Touyama Ie?) is a generational family during the Edo period, and family to the protagonist, Kinji Tohyama. Formed from the founding ancestor, Tohyama Kinjirou (遠山金四郎 Tohyama Kinjirou?), otherwise known as Tohyama Kagemoto (遠山景元 Tōyama Kagemoto?) from his childhood. According to Japanese history around the Edo period, his vagabond life from a Tokugawa samurai official to assist the commoners revered him a legend to the present as we know as Tohyama no Kin-san (遠山の金さん Tōyama no Kin-san?).

Following the present timeline in the Hidan no Aria, all the male members of the Tohyama family inherit a genetic trait called Hysteria Savant Syndrome or HSS. Tohyama no Kin-san's sense of justice passed down to his descendants, influencing them to become great leaders of justice, strength, and law through guardian duties. In fact, a Tohyama can be defined not only for their battle prowess, intellect, and social graces, but also for their affinity toward the concept of justice. No what path a member of this takes, they will always follow that sense of justice to the letter.

The Tohyama's also appear to be rather attractive with Kinji described as dashing in his normal form and gigolo while in HSS; Kinichi is cute cross-dressing as Kana; Kaname and Kanade cute appearance. This has lead to a possible side effect of attracting the opposite sex due to throughout the generations since the first Tohyama, beautiful and sometimes, strong and influential women are married into the family. Examples of this are Setsu marrying Magane, Patra marrying Kinichi (Kana), and all of the girls Kinji has attracted throughout the series that constantly fight over him (Aria H. Kanzaki, Shirayuki Hotogi, Riko Mine, Reki, Jeanne d'Arc, Misaki Nakasorachi, L.L. (Elle) Watson, Moe Mochizuki, Kikuyo Kagataka, Kou, Lisa, Katze Grasset, Sarah Hood, Minuet Holmes and Beretta Beretta).

However, according to Magane Tohyama in Volume 12, the family male members have very poor performance with education as shown with him getting third rate grades, Konza being bullied, and Kinji struggling to learn and unable to complete high school[1].

Even though Kinji always complain about money, his family might one of the wealthiest, and most influential in Japan, and/or continent, as they served as leader of the law for generation and probably stay meager to avoid corruption.

Collateral Brothers (Tohyama Siblings)Edit

It's revealed in Volume 11, that those who inherited Konza Tohyama genes form a patrilineality called the Collateral Bros (Gの血族(コラテラル・ブロス)?) (G) from the four, later five members: Kinichi (Kana) (GI), Kinji (GII), Kinzou (GIII), Kaname (GIV), and Kanade (GV)[2]. The G (Gold) and number next to it is a codename according to the siblings birthdate.
