In the peaceful city of Kawado Higashi, a "Gilts Seed" is discovered that causes people's desires to run wild and turn them into monsters. If left unchecked, innocent people might turn into monsters and attack others. In order to deal with the situation before it happens, "Ichika Ikkano" searches for Giltsheed.

At that time, "Haruno Aikawa" is attacked by a Gilts seed monster. Ichika Ikkano, who came across the scene, saw that she had a talent for PP and gave her an ex-device. Then "Haruno Aikawa" transforms into "Xtia Ignis" and succeeds in fighting off the monster.

In response to the request of Ichika Ikkano, Haruno Aikawa, as "Xtia Ignis," helped to collect the Gilts seeds.
