After Ryotaro retries, Yuto Amakawa become the new Den-O after discovering that he's Singularity point, now he protects the timeline from the evil Imagin. On his 16th birthday, a strange cat girl name Himari come to protect when his demon slayer blood had awaken, will this new Den-O handle it.

Alright, so I wanted to think of the ONE Kamen Rider who went well with Omamori Himari besides Hibiki, and who was that? Gaim! Kara Kara wa, ORE NO STAGE DA! (Being Remade.)

After being saved from the Makamou, Yuto has been trained in the Oni ways by Hibiki. Now on his 16th birthday, Yuto not only becomes the new Hibiki but a strange cat girl came to protect him. How will this new Hibiki handle this?

Amakawa Yuuto is trained in the art of Ongekido by Kamen Rider Hibiki becoming a Oni in the processes now he is 16 and he has more than just Makamou after him.

Hey there, this is a idea I thought about as well as a challenge to anyone who wants to do accept it.
