yuki-san
A character made by Futaba Channel's Nijiura board, based on Kotonomiya Yuki. She is usually depiced as identical in appearance to the actual Yuki, but with blue eyes and occassionally slightly ligher hair. She can be identified by her empty/crazy blue eyes, wide smile, and trademark laughter: "Ahahahaha!" (あはははは)
Though she has the same name as the original (who is usually referred to as Yuki-san as well), Yuki-san's name is written as 逝き, with 逝 meaning "die."
