Right after a silence of the Telomere Kingdom, something unusual starts growing larger in the Tilene Kingdom that shares a border with Telomere.

For the crisis, the leader of the Violet Order Lesfina and her subordinate Elicia are summoned to the Kingdom. On their way to the Kingdom, however, they happen to step foot in the forbidden place called the forest of darkness...

Concurrently, at the center of the forest is an apprentice witch named Primm initiating a ritual of summoning a spirit. When the ritual is done, she is faced by a group of monsters that she has never seen.

The three girls' hardship is about to begin now.
