Let's see... You're using the username of a shipping.
You're using their foreign name.
You're subtitle is "Classy", implying you consider yourself a person of good taste.
You're profile page is hard to read (No offense, just might wanna make the pink a hair darker).
You believe you're a Ninja.
You're a girl.
It's hard to pin, but I'd say by your gender, alleged occupation, biography, and status, my best guess would be Janine. Your name choice and Profile page color scheme do conflict this idea, however.
Yeah, I'd definitely give you Janine - Lonely nature. It also works considering a Ninja's cultural placement and you're using the japanese names.
