蓝川有纱

主角们的学妹。有着四分之一北欧系血统的四分之一混血美少女。 在血缘上与主角是远房表亲（远房堂表亲）。因为种种原因来到了日本的美术学园。 虽然比同龄人高，外表看起来也很可靠，但实际上不擅长交流，晚熟且内向。 因为拼命掩饰这一点（看起来态度生硬），在班级里有些孤立。 和主角在同一个打工的地方，也让他成为了倾诉对象，因此很信任他。 名字是有纱(有紗)，但大家因为她的长相也叫她“亚里沙”。 “真、真同学！请救救我！”

Makoto's underclassman who is 1/4 of Scandinavian descent. She knows Makoto from church, and for whatever reason she came to a Japanese art academy. She works as a waitress with Makoto at Kyouko's café: the Modulor. Inconsistent with age and height, although she appears to be mature and reliable, she is actually introverted and unsociable. Because she desperately wants to hide it, when in class she feels isolated. She works at the same place as Makoto, and because she can talk to him normally, she trusts him. Later, thanks to Makoto, she becomes friends with Tsukuyo, Asuza and Madoka. Arisa seems to be able to speak at least five languages: Finnish, Swedish and Japanese as her mother tongues as well as French and English. Arisa seems to have been in love with Makoto for a very long time, however only Kyouko seems to have noticed it, at first. Arisa does not really have a favorite artistic field as she mainly helps her Senpais to finish their work and she is very interested in everything she does. However, we learn later that Arisa seems to be more attracted to painting. Arisa is mentioned in Ai Kiss 2 as being one of the famous graduate.
