Orin, or Suzu as she is known in the English version, is the pint-sized ninja with the giant-sized heart. She studies to become a great ninja with her grand-father, who is renowned as a fighter, but is hindered by a back problem! She's already a master at disguising herself within her surroundings, sometimes using this really neat shadow cloak! When she doesn't train with her grandfather, she studies at Urara Gakuen with the other children, and she's also one of the eight legendary Paladins of Love, Courage and Hope.
Orin is well-liked by everyone because of her kind heart. She's even nice to Yakko and Marin, even though they sometimes make fun of her naivete and her crush on Shiine. She doesn't judge people and she's so cute and innocent! Everytime she thinks of Shiine, who she likes, she goes bright red. It's really cute! However, she doesn't let her feelings for Shiine get in the way of her friendship with Cha Cha, unlike Yakko and Marin who have a hatred/jealousy complex going on. She says that she thinks Cha Cha's the sweetest person, but I think that about describes Orin!
A shot of Orin using some of her ninja magic.
The first is just a picture of Orin tugging on Shiine's robe, blushing, and the second is from the first episode with Orin. She fell from the ceiling, and Shiine caught her, and since then she's fancied the pants -- or robe-- off him.
