Lulune

When Seiichi was told told to buy a horse for making his adventuring easy by Gassur he went to a monster store for buying one and there he met Lulune a donkey who doesn't like humans who are not strong and when any human(male) approached her she would kick him even the shopkeeper as her mother told her she should provide her service to only those she find worthy and strong, when she met Seiichi she tried to attack her, kick her but he easily overpowered her and lifted her with one arm she tried desperately to escape but after trying several times she gave in and recognized Seiichi as her master that she would follow for life. Seiichi started feeding her with delicious human food at first she was surprised seeing a donkey be treated so kindly but later she developed a special liking to human food and become a glutton. When she won the royal cup she evolved in a human form (a beautiful bishojo) through evolution fruit. Seiichi cares for her very much and it is hinted that he has feelings for her during the date they both went to, as the love pendant multiplied while on their date and he gave the pendant to her, Lulune also loves Seiichi very much but restricts her feelings as she thinks Seiichi as her master and she thinks there can be no relationship between her and Seiichi and also for not wanting to be a problem for Altria Grem and Saria. Her favorite hobby is to go out with Seiichi and eat lots of food and Seiichi also loves feeding her as he loves the face when she is eating food.
