Honkai Impact 3rd: A Tale of Guardians Beginning with Zero Noz

My name is Yuto Kisaragi. I’m an 18-year-old guy, currently a student at the rival school across from Senba Academy: Choko High.

I used to be just an ordinary student. Then that train arrived, and I met Kamen Rider Zeronos and an Imagin who called himself Tenzushi. They brought me to this world known as "Honkai."

As a man in a world where men have an extremely high chance of dying, I’m in serious danger. But I won’t let that stop me.

How does that line go again? Oh, right: "Fight for all the beauty in the world."

If they’re fighting to protect what’s beautiful, then I’ll fight to protect that beauty, including them!

But... who am I again?

(One heroine + no harem + pseudo-reincarnation + Kamen Rider + a touch of VG + a touch of crossover elements + semi-comedic + no System + not a power fantasy)
