Author has written 21 stories for Golden Sun, Space Empires, Vocaloid, and Pokémon.

Hi! I'm a male university student. In my spare time, I try writing Vocaloid fanfiction. If you want, take a look at what I've got. If you enjoy, then thanks! I try my best.

Below you'll find several one shots and some series for Vocaloid. I'll try to write more, since a lot of it's old.

Currently working on Night Shots (Kagamine Rin/Len) and a few smaller things. It's all pretty incesty, so if that's your thing, you should totally stick around because there's always more on the way~!

Kagamine Rin Best Girl, twincest for the win, etc.

Have a great day!
