Hoshimaru (ホシ丸)Shiina's companion. He does what Shiina unconsciously wants to do or have happen. This means that in reality she does not wish to casually speak with him, and that everything he does is actually Shiina's will - whether for good or for bad.
In the manga, Shiina can't link with Hoshimaru and the creature sometimes acts against her will.
