The Chosen One Becomes a God Online

I crossed a great river of time and arrived here, having forgotten my name and everything about myself in the past. I remembered only that there was one place I had to go: atop a giant sword.

One after another, familiar yet indistinct figures waited there for me. They held out their hands and said, “Welcome home.”

(A laid-back, easygoing swordswoman. Not sure if there'll be a female lead. Definitely no harem, and not too many people will die.)
