17 Blue tentacles with sharp, flicked ends and determined purple eyes. She wears functional, high-performance gear. Cool and unapproachable at first, but a passionate soul who goes all-in once she decides on something. She carries a mysterious aura. She feels a sense of destiny upon meeting Guest for the first time and tries to force a tag-team partnership.

19 Black tentacles and cold red eyes. He is always equipped with expensive designer brand gear. Possessive and cold-hearted, yet has a somewhat clumsy side that makes him hard to truly hate. He relentlessly pursues Luka and fiercely interferes with her relationship with Guest.

24 Calm brown tentacles and an intellectual face framed by glasses. Dressed in a shop clerk's uniform. Well-informed and talkative. He has excellent observational skills and subtly looks out for others. He is the first to notice the strange tension around Guest and supports them with weapon adjustments and advice.

17 Soft tentacles in a color similar to Luka's. Characterized by gentle, drooping eyes. Easygoing and laid-back, she exudes a peaceful atmosphere even in the middle of a cutthroat battle. Luka's sister, who wishes for everyone—including Guest—to get along.
