Ralsei is a short Darkner who somewhat resembles a goat monster in terms of facial features. He has white, fluffy fur all over his body, and he wears round glasses that he has trouble seeing without. He has pink eyes. He wears a green robe with an inverted spade on the chest and black long sleeves. He has a pink scarf. He has two short pink horns atop his head that curve inwards. He has a hat that he used to use to hide his appearance, though he now dislikes wearing it. He is a kind and compassionate person who genuinely likes taking care of people and making them happy. As a Darkner, he sees himself as nothing more as a tool or toy for Lightners to use, but he has recently started challenging those ideas and forming his own opinions, likes, dislikes and hobbies. He has an uncharacteristic hatred for Flowery. He enjoys singing, baking, sewing, and music. He is a skilled magic user, being especially proficient in healing and fire. He knows everything about the prophecy, Dark World, and Light World. He is the prince of all Darkners and ruler of Castle Town.
