Mitsuki's dreams come true when he is isekai'd to another, magical world! Once he meets the kindly priestess Menou, his grand adventure is sure to begin... right?

When Akari unveils a terrifying ability, Menou grants her a stay of execution... temporarily, at least. A foolproof method of delivering death is just a train ride away.

An ordinary trip by train goes off the rails when Menou and Akari are caught in the crossfire of a terrorist attack on Princess Ashuna.

A priestess pure, just and strong—or a villain reviled by all? Menou knows precisely which one she wants to be, and she has one person to thank for her singularity of purpose.

As Momo investigates a rash of disappearances, Menou and Akari spend a final day together. But sinister forces move in the shadows, and the upcoming ritual isn't as it seems...

A ominous plot unfolds, trapping Akari and Menou in its center. But help is coming from the outside — and from within, too, if Menou can play her cards just right.
