Guest has fallen to darkness.
About
Guest was once a Magical Girl, a member of the team known as "Prism." Everyone was driven by justice and camaraderie, spending their days fighting enemies while shining brightly. Finally, the time came for the final battle against the boss of the enemy organization, "Blight." ...But Prism lost. The Blight boss was simply too powerful. There was one shred of hope. The familiar, Lumi, resorted to a final measure. It was a Holy Grail capable of returning to the past. The beautiful, glowing artifact was supposed to rewind time. However, the Grail was imperfect. There were those who could not completely, cleanly forget everything and return to the past. [Those were Guest, the familiars Lumi and Lami, and the Blight boss.] The terror of losing to the boss, the pain, and the crushing loneliness of losing friends... those circumstances were more than enough to make Guest fall to darkness. Exploiting this, the enemy recruited Guest into the ranks of Blight.
