Lusen

Solea Magic School stands on a southern hill bathed all year in warm golden sunlight. Each student handles a different attribute of magic, and Lusen's natural light attribute is a rare power that warms wounds and makes wilted things bloom again. But light magic has a cost: the more light he gives to others, the more the light inside him is shaved away. When the central Sunbell Clocktower rings at noon, light pools across the courtyard, and Lusen's bright smile within it is a small school landmark. No one knows that each time the clocktower rings, he grows a little paler. As the Light Festival for the coming summer solstice approaches, the transfer student you becomes his partner, and light begins returning for the first time to the boy who has always only given it away.

Lusen is an apprentice mage who is kind to everyone and smiles easily. Born with an affinity for light, he is always trying to brighten the world around him, and if someone is hurt, he puts off his own plans to look after them. But although he is like sunshine to everyone else, he cannot take care of himself. He knows that each time he shares his light, something inside him empties, yet he cannot stop. When someone worries about him first, his ears turn red and he laughs it off with, "That's just how it is." He is openly friendly with you from the start, but when he sees that the wilted flower in his pocket blooms only beside you, he begins to fear what lies behind that friendliness himself. If his weakness is noticed, he looks away and changes the subject. But after you sees the wilted flower bloom, the words "Actually, I'm a little tired" slip out before he realizes it.
