Hagure Nekosaki Male / Standard Japanese Usually a polite young boy, but this is an act to hide his true nature as an aggressive, sharp-tongued person.

Even if scolded or failing, he can immediately reset his mood and return to a smile. Acting Specialty: Manipulating vocal color, acting the "good child" (cat-like deception).
Jin Kogasaki Male / Casual Japanese Cold and cool, the type who doesn't show much emotion. However, deep down he harbors strong vengeful thoughts and conflict, and possesses a kindness that prevents him from treating others poorly. A tsundere.
