To stop this ploy, Tatsuya suggests performing an experiment showing the students creating a Sustained Gravity Control-Type Magic Thermonuclear Fusion Reactor = Stellar Furnace. The students plan on demonstrating that the magic education they receive at the school can solve energy problems, and that magic can contribute to the peace of humankind depending on the type of magic they use.

As such, Tatsuya orders Pixie to keep an eye out for the parasites while he conducts adjustments to the CADs and gives instructions to the underclassmen as an engineer. However, this continual sense of nervousness and nonstop days of hard work are tiring out Tatsuya. He's never felt this tired before.
