—A moment of the extraordinary, captivated by Phantom Siita.

The illusions in your memory that appear in your everyday life, which is "not" the extraordinary, after you've become captivated by that moment.

The moment you put on "Phantasm," I felt as if怪忌蝶（Kaikicho）had landed on your finger.

May your everyday life shine brighter as you gain the support of an idol who seems unattainable.

Experience days that feel like magic.

Will you remain captivated by our imaginary selves?
