Well... You throwing a book at me to grab my attention kinda reminded me a bit too much of this scene from Clannad. So that pretty much got you the Tsundere title. Besides, it's kinda tsuntsun to grab my attention by throwing books.
You're the Classy Wizard of Reborn. You're a wizard, but you're also a British gentleman. But all the while you're also strange and eccentric. You probably live in a big fancy house with various magical gadgets. Imagine an anime version of Dr Strange.
Your character type is personified by anime wizards such as Tokiomi Tohsaka from Fate/Zero and Elias Ainsworth from The Ancient Magus Bride.
You're the School Nurse of Reborn. You're young, twentysomething, always wears a lab coat, can typically serve any scientific function as needed by the plot and will likely be much more capable than most doctors with Phds in real life.
Your character type is exemplified by characters such as Nurse Joy from Pokémon and Medusa from Soul Eater
You're the Mayadere of Reborn. That is, you used to be evil and an antagonist to the Heroes of Reborn. But since in Anime, Defeat Means Friendship, you were converted to the good side, and now you're officially one of the good guys!
Your character type is exemplified by characters such as Fate from Lyrical Girl Nanoha and Sasuke from Naruto.
You're the Nisetoshi of Reborn. You look like a small girl and act like one, always fooling around and having fun. But in reality, you're a 700-year-old being of immense power, with immense wisdom and strength. Yup, I think that one fits pretty well?
Your character type is represented by anime characters such as Shinobu from Monogatari and Holo from Spice and Wolf.
You're the Chuunibyou of Reborn. Saying you have a large capacity for imagining things would be an understatement. You genuinely believe you have magical powers, and you purposefully dress up as characters from Anime and use unusual speech patterns to try to sound cool. In short, you're a chuunibyou... (It's kinda hard to describe)
You character type is represented by characters such as Rikka Takanashi from Love, Chuunibyou and Other Delusions and Tomoyo Kanzaki from Inou Battle
And finally, the last one.
You're the Transfer Student of Reborn. The author of Reborn could probably have taken their time to write a proper introduction for a new character, but it seems that they were lazy and resorted to the ancient "Transfer Student" trope to introduce a new character. You don't really have a set personality, but a plot device to diversify the cast. Aren't you lucky?
Your character type is represented by such amazing characters like Suzaku from Code Geass and Takeru (TK) from Digimon.
Oh boy, I'm finaly done with every single request!
