The Girl Who Wants to Be a Hero and the Girl Who Ought to Be a Hero, Vol. 1 by Inori read by Adelaide West

IT TAKES ALL KINDS TO MAKE A HERO! After the Great Human-Demon War comes to a close, humanity establishes the Hero Institute, a school for training the next generation of heroes with the assistance of magical devices known as Gear. Ruchika, a free-spirited demon girl with a knack for fighting and zero interest in book learning, journeys to the human realm in hopes of joining the Institute. There, she meets Leonie, a star in the classroom who struggles on the battlefield despite being the daughter of the Almighty Hero, who defeated the Demon Lord. Instantly falling head over heels, Ruchika proposes to Leonie—right in the middle of their entrance exam! Do these two girls have what it takes to overcome their weaknesses and become heroes? And can love really bloom between a human and a demon?
