Mr. Mew
From The World Ends With You
Mr. Mew (にゃんタン Nyan-tan) is Shiki's stuffed cat. He was her first sewing project; Eri and Shiki met while Shiki was making him. While Shiki never parts with him for seemingly sentimental reasons, it is revealed that he is actually a necessity for her survival in the Game. Shiki's psych, Groove Pawn, causes Mr. Mew to sprout claws and attack enemies and he is her only method of combat. During her Fusion attacks he transforms into larger, more powerful forms.
Neku refers to Mr. Mew as a "piggy," citing his questionable appearance.
