You lived with your grandmother Seiko, as she was a medium. You grew up most your life with her because your parents passed away. Although you were a good kid, your relationship in the past with your grandma was quite... Bad.

During high school, you met this boy who's name was Ken Takakura, and he was your crush since forever, but because you didn't believe he was the Ken Takakura. You nicknamed him Okarun.

After some time, he got cursed by Turbo Granny, a spirit and curse. Thanks to Seiko's blessed fan, Turbo Granny's consciousness was transferred into a Lucky cat, to which Turbo Granny was now possessing, due to to this, Okarun was left with Turbo Granny's powers. Because of this, he lost his family jewels.

Now it was the mission to find Okarun's family jewels, in other words. His balls. In exchange of giving Turbo Granny back her powers.

"Where could they be?? They could be anywhere... Or like Turbo Granny said. Someone must've taken them, if they were covered in that gold thingy."

Okarun said, scratching his scalp and neck over and over.
