Summary
Inui Arihiko is a supporting character appearing in Tsukihime and Kagetsu Tohya. Born on October 24, he stands 174cm tall and weighs 62kg, with blood type B. He serves as Toono Shiki’s classmate and best friend, a bond that dates back to the period when Shiki was residing with the Arimas. Arihiko maintains a competitive streak toward Shiki, specifically driven by a desire to secure a girlfriend before Shiki does. The narrative highlights that Shiki occasionally struggles to recall the origins of their friendship, partly because he views Arihiko as having a "weird personality." However, Arihiko’s loyalty is evident during a crisis; when Shiki collapses in class due to his condition, Arihiko loudly alerts the teacher to excuse Shiki and then assists the physically weakened Shiki to the medical office. This act of care suggests a depth of character that may explain why Shiki remains friends with him despite Arihiko’s occasionally callous demeanor.
