Ichika and Lingyin battle in the class league match, but they are interrupted when a mysterious IS attacks the arena. As Ichika and Lingyin hold off the IS so the audience can escape, they soon realize that the IS is an unmanned drone called a Golem due to its mechanical behavior. Together with Cecilia, the three of them manage to defeat the Golem, but not before it injures Ichika. As Ichika recovers while Lingyin watches over him, Ichika wonders if the promise that he made with Lingyin had a different meaning, in which the latter quickly denies. Meanwhile, Chifuyu and Maya examine the defeated Golem and confirm that it is an unmanned drone with a unique IS Core apart from the other 467 IS Cores that the world actually has, leading them to question who would make such a thing.
