Harukiyo "Harukiyo" Sehateno

    About

    He is the leader of "Harukiyo Clan" and a Mushitsuki who processed the power that rivals or even suppress that of Daisuke's. His bug is a giant Tiger Beetle that produces high temperature flames intense enough to burn or melt anything.

    He is allied with Miguruma Yaeko, the vice-presedent of Central SEPB branch. He is only interested in battling with strong opponents. Although usually described as savage, cruel and heartless, he actually cares a lot of his "friends".

    He seems to be targeting something hidden deep inside Central SEPB's underground facility.


    He wishes to be punished by the strong, so in Mushi-uta Bug he was looking for Mari as he felt that Mari is strong enough to punish him. He felt very depressed about Mari's death. He later traced down Mari's Morpho Butterfly and started to follow Arisu. Although he did not recognize Arisu's strength, he did reveal his dreams to her and promised to watch over Morpho Butterfly to the end. He also joined the last battle of "Meteor Night."

    He is the one who responsible for burning down Aoharima Island while battling Sanpikime, but he did not kill the residents on it.

    He is finally able to approach his target - Arisu, at the end of Volume 12, but as soon as he awakens Arisu, he is immediately defeated.

    Before the final battle, his mind was polluted by C's psychological attack and sees the illusive version of people who died because of him. This caused him to fall into despair. Sanpikime injected the memories of Daisuke into his mind and saved his heart through a illusive battle with Kakkou. Harukiyo was able to stand again and stop Daisuke's bug from turning into mature state. He was very active in the final battle.

    He was last seen targeting Yaeko, who appeared in front of Chami. Whether he succeeded in doing so or not remained unanswered. Which organization he currently affiliated with is also not answered.

    He is voiced by Takahiro Sakurai in Drama CD adaptation.
