Liefe no Shukufuku: Muzokusei Mahou shika Tsukaenai Ochikobore toshite Hottoite Kudasai

It is said that Liefes are only capable of conjuring the most difficult and least useful of spells... but that won't stop Yui from doing what she loves! Despite being born a Liefe, Yui adores magic and learning all she can about it no matter the challenge. The more difficult spells, the better! If only her noble father approved. Deemed a failure to the family name, young Yui and her mother are banished from their own home... but she won't let that stop her either! After years of struggle and devotion to her studies, Yui is accepted into one of the most prestigious magic academies in the kingdom. Here she will learn from the best magical practitioners in the world—if she can survive amongst all the pompous nobles with more bluster than brains. Constantly ridiculed and undermined by her privileged peers for being a Liefe, will Yui be able to study in peace and prove them wrong? And what ancient mysteries will her research uncover? That is, if the academy doesn't stop her first...
