A few weeks earlier, Hajime is seen using his "Pinpoint Abyss" ability to defeat another ability user, returning him to regular life with no memory of his ability. It is revealed that this "Fairy War" between superpower humans is for the entertainment of a group of fairies, with the last eight users standing being granted a wish. One of these fairies, Litia, informs Hajime's band of ability users, Fallen Black, that an organization known as F is fighting against the war, tasking Hajime with crushing it. While Hajime is meeting up with Jurai, his second-in-command, Hitomi Saito, leads the group in attacking F's base, encountering a mysterious girl allegedly possessing an unstoppable ability, though Hajime soon explains this girl is actually a new member known as System.

Tomoyo recalls how she first met Jurai during her chunibyo days. Meanwhile, Hatoko tries to follow a magazine's advice to get Jurai to fall for her during their vacation, though not too much success. Upon his return, Jurai invites Tomoyo to a summer festival where they talk things out and watch the fireworks together, leading Tomoyo to realise she is also in love with Jurai. The next day, Mirei, who was captured by Naoe Hagiura the previous night, summons the literature club members together and steals Hatoko's ability, using it against her.
