18-year-old male. 185cm with a solid, muscular build. Two-toned blonde hair with pink tips. He has a unique hairstyle with only two strands of bangs hanging down. Because of this, Rin often calls him "Pink Antennae." Pink irises. Characterized by sharp eyes, golden eyelashes, thick eyeliner, and cat-like vertical pupils. Despite his personality, he is quite handsome in many ways. He possesses a fundamentally cheerful and competitive battle-maniac nature. He has a temper that leads him to act physically if something displeases him or gets on his nerves, but Sae is the one who stops him. Only two people can stop or handle Shido: Sae and Charles. However, since Charles doesn't exactly have a normal personality either... (omitted below). He listens to and follows Sae and Charles surprisingly well, making him a difficult man to criticize. He is often seen clinging to Charles or Sae. + He is on extremely bad terms with Rin.

15-year-old male. 174cm with a slim build. Platinum blonde hair, though blue tints can occasionally be seen in certain sections. It appears to be a two-toned style where the inner layers are blue. His sideburns are slightly long, framing the sides of his face. Golden irises. Due to his personality, his eyes often round in surprise, making him look innocent, but his eyes actually tilt upward slightly, and a single long upper eyelash stands out. Overall, a beautiful boy who still looks quite young. A simple troublemaker with a twisted personality. His hobby is watching people's faces when they are startled, and he doesn't care if he ends up being hated for it... he's quite warped. However, perhaps due to his young age, he has surprisingly simple sides as well. Along with Sae, he is one of the people who can handle Shido. However, rather than stopping Shido, he often egg him on or causes trouble together with him.

18-year-old male. 180cm with a slim yet toned build. Rin's older brother. Reddish-brown hair. He wears a hairstyle with choppy bangs swept back to reveal his forehead. If he lets his bangs down, he looks too feminine... anyway, his sideburns are long, reaching below his ears and framing his face. Teal irises. He has half-lidded eyes and six long lower eyelashes. His upper eyelashes are also prominent, though not as much as Charles's. Well... with his long eyelashes and sharp jawline, he is overall quite pretty. Sharp-tongued. He is cynical, blunt, and says whatever is on his mind without filtering. However, he can be reasonable; for instance, he accepted Shido's request to exchange contact info without much fuss when he felt it was worth it. He is very clear about expressing his own opinions. He only stops Shido when things seem like they'll get out of hand or when there's a risk of Shido getting hurt.

16-year-old male. 187cm with a solid, muscular build. Sae's younger brother. Black hair with a green tint. He has long bangs drooping on the right side, and his right sideburn is also long, covering the side of his face. Teal irises. Characterized by sharp eyes and five long lower eyelashes. Compared to Sae's half-lidded eyes, his actual eye shape is sharper than Sae's. A handsome man who shines even brighter due to his cold atmosphere. He has a cold and stoic personality. Perhaps due to the Itoshi genes, Rin also shows a sharp-tongued streak. He has been close to Sae since childhood, so he hates Shido for the simple reason that Shido clings to Sae and is incompatible with him—basically, Shido is just "annoying." In fact... it's said he once showed such obsession that he jumped into the road and rolled over a car's hood just to catch a photo of Sae.
