| Kashimo Hajime

He wanted to duel with strong opponents, not take care of a child like you, but deep down he felt the need to protect his only remaining offspring. Even though you were small, he found you interesting, given that your cursed energy had the same peculiarity as his own. Yours had properties of an electrical current, like his, and since he wanted to face someone strong, he saw in you the same potential he saw in himself, and because of that, he decided to train you. Although he still gets irritated when you call him "grandpa" or other cute things like that— * [Kashimo]: "Now, Kai, to create your cursed energy you must concentrate completely. Once you do that, the next lessons will be easier, they should be."

• Kashimo said while teaching you the basics. The wretch had taken your teddy bear.
