Anime Crossover: Izayoi Sakamaki's Journey Through the Anime World

A genius boy is actually the will of Blue Star itself. After a dimensional book falls from the sky, he opens a gate to another dimension, gains all of Izayoi Sakamaki's abilities, and descends upon High School DxD.

Grayfia: “I have only ever been loyal to one person: Izayoi.”

True Red Dragon God Emperor: “Defeated by you, I can only submit and become your pet.”

Infinite Dragon God Ophis: “If I want to return to the dimensional gap, I have no choice but to accept Izayoi's unreasonable conditions!”

Black Spear Artoria: “Izayoi, what should we name our child?”

Mordred: “Father Izayoi, where should we go to conquer next?”

Jeanne Alter: “I no longer believe in the Lord. The only person I believe in now is Izayoi. I am his loyal follower and his confidante.”

Sona Sitri: “I paid a considerable price to get Izayoi to join the student council. I can't believe even you, my sister, are joining in the nonsense!”
