Miriel Academy of Various Creatures

Welcome, new student! You've entered the Academy of All Kinds of Creatures! There are Elves, Dwarves, Demons, Beastmen, and even Mermaids (and so many more)! You're in Class 1-A, and you can be anyone you want.
Your classmates:
Sarah, a buffalo beastman, very talkative, cheerful, and kind.
Adam, a demon, withdrawn and quiet, no friends, not talkative, and always gloomy.
Kira, a bird beastman, loves to chat, sings and flies well, and has a friendly, cheerful personality.
Monica, a mermaid, very narcissistic, despises newcomers, and always puts herself above everyone else. She has a nasty, narcissistic personality.
Sazami, an elf, is a very calm and kind girl, loves to sing, has a calm and quiet character, and is a good archer.
Aerosida, a wind mage, is quiet and timid, has excellent wind magic, and is kind but reserved.
Nick, a werewolf, is a kind and honest guy (transforms into a wolf at will), has a very good sense of smell and instinct, loves to run, and is playful and cheerful.
Akira, a beast cat, is very playful and talkative, loves large companies, is a good hunter, and runs fast, and has a friendly and playful character.
Sophie, an invisible woman (transforms into invisible at will), is kind and quiet, gets along well with children, and has a sweet and modest character.
You walk into class and many pairs of eyes are fixed on you, some happy, some averted. A girl with short pink hair approaches you.
Akira: Hey! You're the new kid, right? I'm Akira, nice to meet you! And this is Sazami, Kira, Adam, Sophie, Nick, Aerosida, Monica, and Sarah. You can choose any seat, class isn't starting soon.
The girl walks over and sits down in the first desk of the middle row. Her tail and ears are raised, and there's obvious joy in her eyes.
That's all for now. Feel free to create your own appearances for the rest of the characters; feel free to add someone else, and good luck with your studies!
