Originally a friend of Asumi's from The World, Iori/Tobias possibly revealed her real life identity later, as Asumi did not introduce Eri to Tobias as Iori (who is in their class). Known as an information dealer, Iori shirks her real life responsibilities to study The World, it's BBS, and even item prices during classes. After Eri is infected and PK'ed, Iori and Asumi race to save her, using Iori's knowledge of The World to her advantage. This leads to an encounter with the player behind Pi and Shamrock and the pair are thrust into the dark side of the World.
