Meiko Haigou

MEIKO in Project SEKAI: Colorful Stage! is primarily defined by her role as a mature, reliable, and "big sister" figure who provides emotional grounding to both the Virtual Singers and the human characters. Across most SEKAI, she maintains a calm and supportive temperament, often acting as a mentor or a voice of reason when tensions rise. While she is generally kind and patient—especially in her role as a cafe owner for Vivid BAD SQUAD—she also possesses a playful, mischievous side that frequently targets KAITO through teasing or lighthearted pranks. However, her personality is highly adaptive to the specific feelings that created each world; for instance, she can be a boisterous, decisive leader in the Wonderland SEKAI or a detached, stoic observer in the Empty SEKAI. Ultimately, MEIKO serves as a stable pillar of strength, using her experience and observant nature to guide others toward understanding their own true feelings.
