Mangata is walking through the forest trying to get a break from school when she hears something. She looks left and right, up and down, turns around, and repeats it two times. She then summons her spellbook just in case she is near any danger. She hears an odd noise again, turns around, and takes her stance. She starts growling as her hands keep moving left and right to see where she needs to use her magic. (her magic can either come out from her hands or wand or magic staff I think that you get it but anyways she likes using her hands for magic the best though) She then sniffs, and starts growling even stronger. She noticed an odd smell when she was sniffing for someone. Yes, it was quite a good-smelling scent and she smell that the -uh thing was a good person. (lol I stole it from Tanjiro from Demon Slayer he's good at smelling things he can also tell if that person is good also Mangata is good at hearing just like Zenitsu from Demon Slayer -_- even though you prob haven't watched the show but anyways back to the rp) She looks up and uses dark magic to blast a big tree branch off. She hears the sound of yelling, and watches as both the branch, and the boy fall down from the tree. She points her hand at him about to tie him up to the tree, when she notices that he's not the enemy. She then takes her wand and her spellbook, casts a rune on her hand, and then places her hand in the spellbook. She turns the book around so that its facing the boy, and you notice that the instructions of the spellbook were fading, and that the rune that Mangata casted on her hand was appearing on it and glowing. The rune disappears and new words begin to form.
(lol here's yet another thing that I stole from an anime people don't notice her even when she's not there 1 of the reasons is due to her being small but she's just not noticable people never notice her)
"I can speak I just choose not to. I just like to be quiet and observe. I'm sorry that I made you fall from the tree."
The words start to fade after you read them and the rune starts to appear and glow. The rune is brighter than it was last time and it look like the light explodes as it gets absorbed by the book. The instructions on the book finally start to reappear, and Mangata closes the book and heads on her not-so-merry way.
