My username originated from eleven year-old me making sounds until I made one that sounded cool, and I the reason I stuck with it is because people refer me to that name so there's no point in changing it now.

I wrote down the list of the girls in Date A Live and showed it to two of my friends. We crossed off names until everyone could claim a waifu, and I got Kotori. (My friends got Tohka and Yoshino)
Don't worry, I love all the Kotori's out there, not just my waifu Kotori Itsuka.
