Mahou Senshi Louie

Louie, a brawny student at the mage's guild, is reluctantly accepted by three girls (Merrill-thief, Genie-fighter, and Melissa-priestess) as a companion for their adventuring party. As the foursome explore ruins, battle dark creatures, and make new friends, they also uncover a sinister plot within the kingdom. (Source: ANN) Louie is a mage student of the mage academy, and adoptive son of the director. But still, he sucks at magic. Instead, he has abilities for drinking, flirting and fighting in taverns. One day, he meets a party of girls (a priestess, a warrior and a thief) looking for a mage to join them to open a ruin entrance, but they absolutely rejects him due to his pathetic magic skills. But he refuses to be rejected, and then he tries to join them by force, only to interrupting a sacred ritual of Melissa (the priestess), revealing Louie as her master.
