Kamen Rider Eternity in the Manga World

When he wakes up, the eighteen-year-old young man Sakuyong travels to a completely unfamiliar world. There are Kamen Riders he is familiar with, girls from anime, and monsters that should not exist in reality. What's even more outrageous is—— He has an extra Lost Drive around his waist. I have an extra T2 Eternal Memory in my hand. And he himself became Kamen Rider Eternal. Facing Amazon rushing in from the rainy night, Sakuyaga understood for the first time that there was no so-called "plot protection" in this world. Someone will die. Someone is going to lose a family member. Some people will kill the people they value most with their own hands out of desperation. But now that he already has the power, at least... He wanted to save the person in front of him. "What kind of Kamen Rider am I if I can't save the person in front of me?" However, becoming a Kamen Rider is only the beginning of trouble. Because he soon discovered that the world was far more chaotic than he imagined. Yukinoshita Yukino, Sakurajima Mai, Kasumigaoka Shiu, Takasaka Kirino... One after another, girls who should exist in different stories are meeting in this world. And what's even weirder is—— Yukinoshita Yukino seemed to be able to hear his thoughts. Then. The white demon knight, who looks extremely cold on the surface, and the otaku who is madly complaining in his mind, begin their story. "Wait, Yukino, did you hear something?" "No." "Really?" "... No." "Then why are you blushing?" "Shut up."
