Aeris Nightstriker is a character in the role play Mystical Community. Throughout most of the storyline, Youichi_Hiruma (Hiruma) had yet to create her character so she was dubbed "Youichi". However, when Hiruma finally created her characters, she wanted to name it Aeris Nighstriker but the previous Players' mentionings of her led to Aeris having the nickname "Youichi". Aeris is the second-in-command of the Mystic Council and is usually the one who assigns targets from the Bingo Books. Regardless of her work at the Council, she is also Headmaster of Chronos Academy.
