Actually SAmurai, Callin' has written Kourin and Callin' in several places. They are a very confusing artist...but most hte time they use 高鈴.
This page really needs to merge already...
KOURIN never was correct tag! romaji never been ised as tag, since japanese use thier kanji, hiragana and katakana. romaji tag is incorrect! (used by oversea fans to recognize artist, but its not right tag)
