Mr. Mew is Shiki's beloved stuffed cat. He doesn't seem to do much at first, and Neku originally views Shiki's obsession over him with distaste, calling him a stuffed pig. But when the duo get into battle against Noise, he is controlled by Shiki to destroy them. However, Shiki later tells Neku that all she does is send Mr. Mew flying torwards the enemy, and Mr. Mew attacks on his own. It is later revealed that Shiki made him, encouraged to do so by her best friend Eri.
