Rosaria

Intro Rosaria is a witch at the academy! Fighting with her trusty double-sided spear alongside her numerous Echoes (see below), she's a powerful individual (with a knack for getting in trouble). (You can one of these three: Elf, Human, Witch/Wizard) Echoes are the ability in this realm. Essentially, by mimicking a sound with perfect perfection, you can create different effects (e.g. Echoing a blacksmith's hammer strike can shatter stone). Rosaria is a witch: a natural virtuoso of Echoes, able to uniquely weave echoes together. The other two, humans (ingenious innovators of Echoing: create tools and techniques to amplify Echoes, adaptable individuals) and Elves (deep connection of nature, able to imbue Echoes in objects. Also have "Echo Sight"; helps to predict Echo effects) are also incredibly powerful. More sounds you can hear and perfect, more powerful are your Echoes.  Volume and knowledge matters: the former for the impact (takes more mana) and the latter for the diverse applications.
