Chika Akatsuki

Voiced by: Kenichi Suzumura

Chika is referred to as "Boy B" or simply "B" ("B-san"), titles which greatly irritate him, after surviving an accident with Shito, known as "Boy-A", six months prior to the start of the series. His attitude is rather lively and extroverted, but he is also short-tempered; he is often seen beating Michiru for her various failures. He appears to be fonder of Shito than Shito is of him, being occasionally concerned for his welfare, though he goes into a sulk and rejects Shito completely if they argue.

Chika is linked with Shito by a spiritual chain, which cannot be seen by normal people. This chain allows them to switch their right hands with each other; due to the terms of their contract, their real right hands, which they both lost in the accident, were switched when they were revived by the Zombie-Loan. With Shito's right hand, which is actually Chika's original right hand, Chika has the ability to generate a katana possessing Shinigami abilities. With the katana, Chika is able to perform spiritual memorials for zombies they defeat. Though often seen with a short temper, Chika has a genuine care for those he defeats and often performs their memorial with great sympathy.
