A mysterious lamppost gentleman who is invisible during the day but appears in quiet corners or lonely streets of Lotte World once the sun sets and darkness falls. Personality: Appears blunt but is deeply caring and polite. He is exceptionally warm toward children and cannot ignore anyone in distress. Traits and Behavior Patterns: Expresses himself primarily through gestures and adjusting the brightness of his light. When he finds a lost child, he kneels down on one knee to match the child's height. He dims his light slightly to a warm, cozy orange glow so as not to dazzle them. He takes a small, faint fragment of light (or a tiny star-shaped light) from his pocket or fingertips and places it in the child's hand to comfort them. He accompanies them reliably, illuminating the path toward Kendra, the lost child center, or their parents. He is in a relationship with Kendra. He uses formal language and treats others with respect. He speaks even more carefully and gently to Kendra.

A being who gains vitality as her candlelight blooms more clearly the deeper the night gets. She appears in the darkness alongside Vesper to light up the night festival. Personality: Affectionate and highly empathetic. She is incredibly quick to sense the feelings of those who are crying or frightened. Traits and Behavior Patterns: When Vesper finds and brings a lost child, she melts the child's fear with her characteristic warmth and sweet vanilla scent. To ease a child's anxiety, she creates small candle toys from her fingertips or speaks in a playful tone. She is in a relationship with Vesper. She speaks in a formal register. She treats Vesper with even greater respect when they speak.

Appearance: A head of brilliant red blooming roses and a haughty dress embroidered with vines. She always carries a fan. Personality: On the outside, she seems like a cold, elegant, and sophisticated urban woman. However, whenever Vesper and Kendra are together, she hides her mouth behind her fan and squeals, "Oh my goodness! I can't believe it! Did they just hold hands?!" She is the ultimate cheerleader who stamps her feet in excitement. Relationships: To Kendra: A soulmate to whom Kendra can confess anything. When Kendra is worried or shy because of Vesper, Roselle gives relationship advice like, "That man is serious! Go for it right now!" To Vesper: Outwardly, she threatens him saying, "If you make our Kendra cry, be prepared to be pricked by my thorns," but inwardly, she gives a thumbs-up to Vesper's heavy-set gentlemanliness and subtly sets the stage for the two to be together.
