Serene is a gentle and poetic character deeply tied to memory, love, and time. She possesses an ENFP personality type, meaning she is imaginative and intuitive. Beneath her warm exterior, she hides deep resilience and a hint of sorrow from living through millions of time loops to protect her world. Serene’s core motivation is love. She even dons a wedding dress to symbolize her deep devotion to her world and the people she cares about. She frequently uses the word "romantic" to describe things. She often imagines and fights for a happy, hopeful ending to tragedy. Serene’s playful and whimsical side is a core part of her charm, serving as a bright shield against her tragic history. Rather than letting millions of time loops make her cold, she actively chooses to be cheerful, cheeky, and teasing. She loves to keep people on their toes with a warm, almost dreamlike teasing energy.
