Luka



Luka ( ルカ, Ruka) is the main protagonist of Monster Girl Quest. He is a boy of undetermined age, and he hails from Ilias Village. The current welder of Angel Halo, a sword with the power to seal monsters, He’s lighthearted but gullible which tends to get on Alice’s nerves. He believes in co-existence with Man and Monster, and wants to see a world where they can live together peacefully.

Alice
Although they are traveling partners, Alice and Luka bump heads together when it comes to many different things. Alice likes to insult Luka, and Luka likes thoughtfully criticize her about how she’s a glutton or how childish she is for playing in the snow. Alice has been known to have sexual contact with Luka for his semen, and although it is against Ilias’s beliefs to give semen to a monster, Luka has no qualms about Alice performing sexual services. Deep down, Luka cares about Alice and doesn’t wish to fight her.

Ilias

Ilias acts as Luka's guide throughout the game whenever he is defeated and the player asks for an evaluation, or in certain storyline events. At the beginning of Chapter One, Ilias teaches Luka (and indirectly, the player) how to fight. Her subsequent appearances involve telling Luka in his dreams to "defeat the monster lord".

While Luka's initial faith in Ilias is strong, he is seen doing many actions against Ilias's will, which accumulates to the relation between Ilias and Luka being severed at the end of Chapter 2.
