Skeith, sealed inside of Sora, encounters Tomonari Kasumi and his girlfriend Mai Minase while they explore a field. Not wanting them to get in the way of his hunt for Aura, Skeith assumes his normal form and attacks both of them. As a result, Tomonari falls comatose, but Mai is able to escape and begins searching for answers about the attack in the real world. Skeith later tries to attack Junichiro Tokuoka when he follows Tomonari's footsteps, however Mai recognizes the tone that plays when he appears, and is able to escape with Tokuoka before Skeith can complete his attack.

Skeith is first seen by Orca and Kite in the dungeon of Δ Bursting Passed Over Aqua Field. He is busy chasing Aura and ignores them at first, but when Aura tries to give the Book of Twilight to Orca, Skeith appears and challenges the two. Orca tries to fight against him, but as a normal player, his attacks are useless. Skeith data drains Orca and places him into a coma, but before he can attack Kite, Helba appears and drives him away.
Over the course of Infection, Skeith continues chasing Aura, attacking any players that get in his way, including Alph, Sieg, and Mai Minase. Eventually he manages to catch up with Aura at the field Θ Chosen Hopeless Nothingness. Kite and BlackRose arrive just as he begins to data drain Aura, segmenting her data into three parts and sending them to various places inside the system. Skeith attacks Kite and his party but is eventually data drained himself and defeated. Though he is destroyed, his death results in the birth of Cubia, the shadow of Kite's bracelet.

Much later, a stronger Kite encounters Skeith while in a field with BlackRose and Mistral. After a hard and mostly unsuccessful battle, Kite manages to unleash the power of the Bracelet, destroying Skeith.
