Usagi is one of the original characters of the series. He is a PriPara mascot Dressing Pafé's manager, as well as Sophie's former manager. He has a friendly rivalry with Usagi due to their similar goals of becoming the number one manager in PriPara. His birthname is Will Michael Georges Sandrelli Mezza Bonjour Francois Girgil Je T'aime IV. This character is RPed with Ivanly912.
Usagi has light blue fur and big black eyes. He has white fur around the nose/mouth areas on his face. On his ears are red diamond patterns, with an 'X' striking through them. He always wears a pair of black sunglasses on top of his head, and he wears a red tie with another black 'X' around his neck. He has a purple cotton tail. He also has a pair of sharp yellow wings.
Usagi is very boastful and judgemental. He is also somewhat easygoing. During his time as Sophie's manager, he seemed to be very proud of her. In reality, he was just using her in order to fulfill his goal of becoming the top manager. He rubbed it in other managers' faces that Sophie was better than most of their idols. Because of his huge ego, he didn't want anyone else to find out about Sophie's 'Fancy Mode', as he believed it would ruin his career. He adds "~usa" to the end of his sentences.
He later hires Dressing Pafé, and consequently became very boastful of them since they made an amazing debut. It is unknown whether he still cares for his former idol Sophie.
