Long story short, there was a place in our world where, if you wound up there, you'd end up facing the parts of yourself you didn't want to admit to. They called themselves Shadows, and they were a real pain. If you didn't accept them, they would kill you. The only reason I survived was Yu-senpai and the others coming to protect me long enough to admit what I was hiding...

...and ours had yellow eyes, too. I have to admit I didn't look bad with them when I wasn't being creepy.
