Yu

Yu is a cheerful female ghost. From Puyo Puyo Fever 2 on, she is accompanied with her twin brother, Rei; they are collectively known as Yu-chan & Rei-kun, or simply Yu & Rei. Yu is loud, whimsical, and incredibly cheerful. She has a love of puns, uttering them in her speech and utilizing wordplay for her pop quizzes. Prior to her ghost life, however, she behaved the polar opposite of her current personality, giving some dark implications that she prefers being dead to living. These implications are confirmed by 20th, as some of her few memories of life are unhappy and she fails to understand why people wish to live when offering to turn people into ghosts, or in effect to murder them.
