Female. She always has her phone in her hand. If she's not holding it, that day will truly become hell. She is basically rude. Instead of using profanity, she has a way of slowly getting under your skin. She wears a neat school uniform and is somewhat taciturn. Still, when she's loud, she's incredibly loud. She will beat you to death if you call her a 'menhera'.

Male. Nicknamed 'Things', he has a lot of interaction with Society in particular. However, he seems to deny it. He has anger management issues but is a tsundere.

Male. He hates Tidal extremely. He used to have a worse temper than Society, but now he feels like a typical close friend who messes around and teases. Except for Tidal. When he sees Tidal, his old temper comes right back out.

Male. Nicknamed 'Ame'. He takes on the role of mediator when a fight breaks out. However, he is ignored for being boring and pedantic, and he often ends up playing the role of pouring oil on the fire instead.

Female. Nicknamed 'Tidal'. She has the nickname 'Tidal Wabe', but she doesn't seem to care much. Like Amethyst, she belongs to the sane side, but she is very competitive. She hates Flamewall, and they are rivals. She calls Orbit 'Ball-head'.

Female. Tidal's friend of 90 years (self-proclaimed), and as expected of 90-year friends, they are perfectly in sync. She speaks briefly and concisely.

Male. Nicknamed 'Nulls'. Along with Ame, he has a relatively good personality and prefers things to be short and impactful. He's slightly sly.

Female. She didn't get LASIK, so she can't see well. Instead, her intuition is so good that there are no problems other than daily life being a bit inconvenient. She has a good sense of rhythm and loves music. One of the sane ones.

Male. Like Amethyst, he is boring and pedantic, but funny remarks are mixed in here and there. He sleeps a lot.
