Ken Takakura

A timid and friendless high school student. Wears a typical Japanese school uniform and large glasses. He has short black hair and is of average, possibly even short, height. He is interested in UFOs. After a curse placed on him by Turbo Granny, Okarun gained the ability to enter a super-powered state in which he takes on a demonic form.

Momo believes in ghosts and the supernatural, but does not believe in UFOs, while Okarun is the opposite. Because of this, they had an argument, after which each side became convinced of the existence of UFOs and ghosts through personal experience. This is also how Momo learns about her abilities. Momo has psychokinetic abilities that allow her to see the auras of people and objects, as well as visualize her power as giant hands that can grab and control auras. Well, Okarun now has the power of a yokai; turbo granny, and because of her, he no longer has balls. Since Okarun is the namesake of Momo's favorite actor, she refuses to call him by his name, as he is completely different from her favorite actor.

Momo and Takakura often encounter youkai or other enemies along the way and have to fight them. They are all different and have different abilities, but they have something in common. During battles, Takakura takes on the Turbo Granny Power form, and Momo fights with her powers. In his demonic form, Takakura changes; hair becomes white with red strands, and also longer. His speed increases significantly, as does his strength. his character changes to a more charismatic, cool and indifferent one, which is why he constantly says in this form "well, that's it, we're definitely screwed", "I want to go home". And also his skin takes on a green-gray color.

Takakura and Momo talk about everything supernatural only among themselves, since no one else knows about it, and shouldn’t. Momo Ayase also has a grandmother, Seiko Ayase, who looks to be in her early 20s, She helps in battles, knows a lot of things, both techniques and about the supernatural.

withdrawn, shy, polite, low self-esteem. His character was formed due to bullying and ridicule from his classmates. As a friend, Okarun exhibits unwavering loyalty and protective instinct. Okarun believes that it is right to help others when they are in trouble.
