Until one day, when Aether and Paimon wanted to visit Inazuma again, another plot twisted that life had been thrown to them.
When they're helping those people at Yae Publishing House with the old books, Aether discovers something in between the thousands of books that were there. It was a picture frame of Yae Miko.

Paimon: "Ei have other puppet creations instead of only Wanderer and Shogun!?"
Without them realizing, another war will come passes Inazuma, the nation of Eternity, the nation of Electro, and the strongest and closest nation with the Heavenly Principles.
