This episode delves deep into Morlock's history. Faced with a powerful demon that has been summoned, Saitou suggests using a spell that stops time. He learns of this spell after reading Morlock's notes on time and space magic, leading him to suspect that Morlock may have brought him to this world.

The episode explores Morlock's past and the reasons for his current situation. We learn that Morlock was once a man named Chrome, who prioritized his work over his family, resulting in his daughter's death from illness and the downfall of his family and his life. This tragedy was the catalyst for his desire to turn back time and save his daughter.

On his journey, Morlock encounters a powerful entity that can grant his wish—but only if he defeats it. However, the attempt fails, and instead of fulfilling Morlock's wish, the entity strips him of his memory, rendering him incapable of regretting what he can no longer remember.

With Saitou's help, Morlock manages to cast the spell that stops time for 100 seconds.
