Skeith

is the 1st Phase of the Cursed Wave and was referred to as “The Terror of Death”. Skeith The Terror of Death is Haseo’s Avatar.

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.

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.

Skeith is shown to BlackRose in a vision created by Mia at Δ Bursting Passed Over Aqua Field. In the vision, she watches as Skeith defeats Orca and attacks Kite, but is driven away by Helba. Later BlackRose travels with Kite and Mistral to Θ Chosen Hopeless Nothingness where she battles with, and eventually defeats Skeith.
