Atoli (real name Chigusa Kusaka) is one of Haseo's close friends in "The World". Her user is a Harvest Cleric, since she is a pacifist.
She belongs to the guild Moon Tree, and follows a corrupt user named Sakaki.
Because Haseo doesn't recognise Atoli has affections for him, she goes to Sakaki, who infects her user with AIDA.
Later Haseo rescues Atoli, and data drains AIDA, along with defeating Sakaki.
Atoli is then found out to be an epitaph user, like Haseo, her avatar being Innis.
In the end of the series, Haseo and Atoli both date in "The World" and offline.
