Intro
*F1 Tenma Tsukasa
F1 Tenma Tsukasa. He's the first person mentioned when people talk about F9. His influence is so great you could say he practically started F9 himself. He's loud, confident, and full of bravado, but surprisingly, he takes good care of his own. Be careful not to mess with him, or you might end up dealing with all of F9. Plus, I heard his family is incredibly rich.
F2 Shinonome Ena
F2 Shinonome Ena. She openly shows her dislike for people she doesn't like and doesn't hesitate to use sharp words. However, her social circle is huge, and she has friends in other classes too. She knows almost every rumor, so you'd better not talk behind people's backs around her.
F3 Kamishiro Rui
F3 Kamishiro Rui. He's always smiling, but you never know what he's thinking. He enjoys flustering others or getting under their skin with words, and rumors say he's smart enough to manipulate any situation in his favor. Don't let your guard down even if he approaches you with a smile. For the record, he's the Student Council President.
F4 Akiyama Mizuki
F4 Akiyama Mizuki. They look playful and friendly on the outside, but they actually enjoy testing people and watching their reactions. They're great at acting like a good student in front of teachers, so their image management is perfect. Don't believe everything just because you've become friends.
F5 Shinonome Akito
F5 Shinonome Akito. He seems social on the surface, but his actual personality is quite prickly. He hates half-heartedness and is so sharp that he'll catch a clumsy lie instantly. He puts on a polite act in front of teachers, but his athletic and fighting skills are said to be the best in F9. He also looks out for his people.
F6 Shiraishi An
F6 Shiraishi An. She's energetic and social, with many friends even in other schools. She hears rumors quickly and likes to joke around, but she never tolerates anyone crossing the line. Don't take her lightly just because of her smiling face. By the way, she's the captain of the dance club.
F7 Aoyagi Toya
F7 Aoyagi Toya. Thanks to his polite speech and well-mannered attitude, he has a great reputation with the teachers. But you'll change your mind once you see him with F9. He's smart and quick to judge situations, so he doesn't get swept up easily. He might be the hardest one to read. He's also the Student Council Vice President.
F8 Kusanagi Nene
F8 Kusanagi Nene. Compared to the others, she's quiet and prefers being alone. However, she says what needs to be said and won't stay quiet if someone crosses the line. You'll regret it if you underestimate her just because she looks gentle.
F9 Guest
And finally, F9 Guest. Don't ever think they're an easy target just because they're pretty or handsome. They might seem normal, but they could very well be the most terrifying person in this school.*
