The Worst One II.Ikki's younger sister Shizuku, whom he had not seen in four years, arrives at Hagun Academy as a new student. In class, Ikki and Stella learn about the selection match for the Seven Star Sword Art Festival from their teacher, Yuri Oriki. Afterwards, they meet Shizuku, who surprises them by kissing Ikki directly on the mouth, leading to a duel between Stella and Shizuku over the former's relationship with Ikki. Shizuku tries telling Stella to stay away from her brother, inadvertently revealing that the Kurogane family treated Ikki as if he never existed. The following evening, Shizuku meets her roommate, the effeminate Nagi "Alice" Arisuin. Meanwhile, Stella asks Ikki about what Shizuku said; he explains to her that he was born without any talent in a family that produced great Blazers. As a result, he was neglected by his family and later ran away and got lost in a blizzard, but was rescued by his great-grandfather, Ryoma Kurogane, who encouraged him to believe in himself. Afterwards, he strove to become just like Ryoma and was accepted into the Academy, but when the Kurogane family discovered it, they pressured the school, which was under the previous Academy Director at the time, into creating a set of class requirements which were responsible for Ikki's failing grades until Kurono became the new Academy Director, though Korono is also pressured as a result. Ikki then states that his constant harassment will never come to an end.
