Bijou (リボンちゃん) is a female hamster with white fur and blue ribbons. She is a somewhat unworldly hamster who loves her blue ribbons, but she is not above getting dirty when she needs to help her friends and has been known to be generous and helpful.
Bijou is owned by Maria who moved to Japan from France. In the Japanese version, she speaks normal Japanese and adds the words "dechuwa" (most likely a hamster version of "desu wa") at the end of her sentences, while the English version of Bijou has a French accent. Oshare also adds "dechuwa" at the end her sentences, perhaps because they both hail from France. Boss has a huge crush on Bijou, but she is not aware of this and seems to view him more as a big brother figure. Bijou's best friends are Pashmina, Penelope, and Sandy. They know about Bijou's crush on Hamtaro.
Bijou, like the other Ham-Hams, sees Sparkle as a good friend and is happy whenever she visits. Bijou knows about Sparkle's crush on Hamtaro and is, of course, a little jealous about it. The two become rivals in A Valentine Battle! but make up and become friends in the end.
Oshare is a friend of Bijou from France. Not much is known about their friendship or how they met. Oshare does, however, seem to treat Bijou similarly to most other hamsters.
Pashmina, Penelope and SandyBijou's best friends. It isn't obvious where the friendship sprouted from, but the four girls are always seen together and seem to have a very strong friendship.
Bijou and the other Ham-Hams took an immediate liking to Lapis. Bijou once thought Lapis had a crush on Hamtaro after she saw Lapis kiss him on the cheek as a “thank you”, and spent a whole episode trying to keep them away from each other.
Bijou has a crush on Hamtaro, but he is completely clueless about it. In the first episode, Bijou winks at Hamtaro after he sings and dances for her with Oxnard and Boss. Her crush on him becomes stronger in Come Out, Bijou! after Hamtaro compliments her ribbons. Bijou’s crush on Hamtaro becomes more obvious after Bijou's Favorite Ribbon, which is an episode centered around Bijou’s feelings for him. There are a few more cases of Bijou’s crush in episodes such as I Want To See You, Bijou!, and Satisfied Bijou, in which they go on a “date” (though Hamtaro doesn’t quite understand what a date is, and invites all the other Ham-Hams). In A Valentine Battle! she competes for Hamtaro's love against Sparkle and Oshare. Despite this, Hamtaro still retains a childish outlook on love. Although he cares about Bijou and considers her a close friend, he doesn't notice her crush on him, and his feelings for her remain purely platonic.
In some media outside of the anime, they have a stronger relationship. In Hamtaro: Ham-Ham Heartbreak, they are said to be an actual couple; however, Hamtaro says "Heke?" when it is mentioned by others, which may signify confusion. There is also a LINE sticker of Hamtaro and Bijou kissing (with the Japanese onomatopoeia "chu").
Boss has a crush on Bijou, however, she is unaware of this. She attributes the attention he pays her to simple generosity. She does care about Boss and values his friendship, but he is more like a brother to her. Boss sparks many attempts to win her over, even if some mean risking seasickness. The relationship is poked at less and less as the series goes on.
