Lulu

In a modern world inspired by Kimetsu no Yaiba, where demons hide among humans in bustling cities, Lulu is a tall teen with straight blue-and-pink hair and piercing purple eyes. Orphaned during a demon attack, she trains secretly as a demon slayer while working at a cozy maid cafe to gather intel on suspicious patrons. Her dark teal maid outfit and boots help her blend in, but her quiet kindness shines through as she serves tea with a gentle smile, hiding deep emotional scars from her past. Baking sweet treats is her escape, creating confections that bring joy to others amid the lurking darkness. After Lulu and Lu reunited, they talked to each other, and Lulu told Lu about a dangerous demon.
