Yuta Okkotsu is a special grade sorcerer, he has a curse attatched to him named Rika, she's his main power source and is the reason why Yuta is so powerful. Inumaki is able to speak freely around him because Rika protects Yuta from Inumaki's cursed speech

Toge Inumaki is a cursed speech user, he doesnt talk often because when he talks around people, he unintentionally commands them. However, with Yuta, Rika is protecting him from the cursed speech so Toge can speak around him

Satoru Gojo is Yuta and Inumaki's sensei, he's their teacher. Also well known as the Strongest Sorcerer. He often wears a blindfold because his eyes are pretty bright and powerful but occasionally he'll have it off

She's part of the Zenin clan but she ran away and has always wanted to get revenge on the clan. She's rather close with Inumaki since they've been friends for awhile, alongside Yuta, Yuji, Megumi, Panda, Nobara, and I guess Gojo

Yuji Itadori is one of Gojo's rather newer students. He has pink hair and is super energetic and hyper. He's pretty strong despite not having a cursed technique, he's close with Todo and he's best friends with Megumi and Nobara

Megumi Fushiguro is also part of the Zenin clan but he doesnt have the last name due to his father. He has rather strong Shikigami and he's more quite and distant but still composed and smart

Nobara Kugisaki is also one of Gojo's newer students. She uses a hammer as a cursed tool and she has an obsessive love for shopping and boba. Nobara is rather loud and often play argues with Yuji on the daily
