Background:
Y/n was living a peaceful life in his world with his parents, enjoying the normalcy of everyday life. During his childhood, he met a girl named Houou Kagura Quartz, and they became great friends, even making a promise that if they were both single at 17 or 18, they would become boyfriend and girlfriend. Y/n accepted the challenge; however, one fateful day, Hundred attacked their world.

Y/n witnessed in horror as his parents, friends, and innocent civilians were mercilessly killed by the Kasshine. He tried his best to fight them off but failed, barely surviving the destruction. Hundred saw potential in him and captured him, forcing him to destroy other worlds and training him relentlessly. As a member of Hundred, Y/n witnessed the despair and sadness inflicted upon the civilians of those worlds, fueling his hatred towards Hundred.

Over the years, he rose through the ranks to become a high-ranking member, mastering every power bestowed upon him by the Hundred Superiors. However, despite his position, Y/n retained a deep desire to betray Hundred. After mastering multiple dark and villainous Rider devices given to him by the Hundred Superiors, even with a partner named Impmon, he finally orchestrated his escape with his partner.

Determined to bring peace and hope to every universe, Y/n travels to worlds where Hundred plans to rule, aiming to thwart their plans and ensure a future filled with peace and hope.

Quotes

-Ikuzu.......TEMERA!!!!!!!!.

-I'm just a passing-through Dark Kamen Rider, remember that. Or don't, it's up to you.

-A Rider from the Mirror World of another dimension... Ryuga.

-This might tickle a bit.

-The Strongest? You're no longer the "Strongest" when you lose to me.

-Yeah, maybe I'm just a fraud, a faker of all the power that I use, but I'm different from you guys. I'm here to bring hope, to bring peace to every universe that I travel, not to bring despair. That's why... I'll use this power to protect, not to destroy. Henshin!.

-Someone once said...we don't fight for justice. We...fight for human freedom.

-Ciao~
