Kai Iod

Kai Iod (カイ・イォド Kai Iodo), formerly known as "The Disaster Yog" (〈災厄〉ヨダ Saiyaku Yoda), is the deuteragonist of the series. He is a spirit from the realm of Hades. Biggest fan of Chloe and a self proclaimed lolicon. He saves Chloe from a bunch of spirits, gaining her trust and consent to enter her body, making her the Ghost Reaper Girl.

Personality
Self proclaimed "lolicon and gentleman", Kai has strong adoration for young girls. On one side he wish to protect their cuteness and innocence. While obviously being a downright pervert.

Despite his perverted tendency he acts like a charming and kind hero. He is very protective of Chloe and is willing to do everything to protect her.

Abilities
Kai's main ability is that he can summon chains that he uses to fight, but he can also turn into a strage scythe that is typically used by Chloe in battle.

He can also return to his title of the Disaster Yog by reverting to a form similar to that of a demon through the powers of Cthulu. In this form, is he able to use his same powers but with more enhanced power-ups. He still mainly uses his chains to fight, but he can also cause large explosions seemingly out of nowhere.

Trivia

 * Kai has a similar character design with Tsukune Aono from Akihisa Saike's previous works, Rosario + Vampire.
