The Demon Army of another world has absorbed various objects and knowledge from the present world and has become even more powerful.
When it comes to things from another world, it’s best to ask someone from another world!
Thinking this, Luna Blythe uses summoning magic to successfully summon the protagonist and his classmate, Kotonose Azusa.
Although it is a confusing situation, Luna asks for help in defeating the Demon Army, and Azusa looks at her with a serious expression, agreeing, despite her concerns about the impact on the present world, and it is impossible to refuse, so she decides to help.
