Yui, Meroko

めろこ・ユイ

Alongside her partner and love interest, Takuto Kira, Meroko Yui serves on the shinigami team Negi Ramen, tasked with collecting the soul of 12-year-old Mitsuki Kouyama.
Meroko is a rabbit shinigami with long ears, possessing the ability to transform into an anthropomorphic bunny plush toy.
She has a fiery temper and can be quite moody, particularly regarding her relationship with Takuto (despite her persistent efforts to impress him, he appears oblivious to her advances and does not share her feelings).
Although she attempts to assist Mitsuki with her singing career, her suggestions frequently land the girl in trouble.
In the anime, she enjoys altering her appearance to resemble other characters, and her signature catchphrase is "Mero Mero Change!"
