Aisaka Sayo (相坂 さよ): Aisaka Sayo (seat no. 1; 1925-1940) is a ghost sitting next to Asakura Kazumi. Although most people cannot see her, the rumour that a ghost still roams the classroom is well-known and her seat is left alone because it said a chill can be felt if one sits in it. Although most humans cannot see her, Takahata most likely could, as he left her on the class roaster. She cannot leave the school grounds, like Evangeline, but still shows up to class every day. She is very timid and lonely. She has no significant role in Volume 1. More at: http://negima.wikia.com/wiki/Sayo_Aisaka
