So far I like this one the best.
Name: Taimu Hanabatake
Animal: Leafy Sea Dragon
Weapon: Japanese Flute
Although Suika is the team leader and Raichi the main character, Taimu is the caretaker of Murasaki. This is because of her soft and gentle voice, as well as her shyness (which makes her unable to talk to people very easily) and her expertise in animal care giving.
Just Lollipop and then I'm done with the mews!
