Old Wolf the warrior remembers a time where there were less wars, He remembers when the brave maiden Ko first took up her father's sword. His love for the girl is what drives him to war - to protect her and her family. Wu the turtle remembers a time where there were no wars at all, there were less people then as well, but he likes Old Wolf because despite being so young he asks few questions.
Shiro the Ninja is a quiet soul and always has been he remains Ko’s patient companion through her life. Perhaps that is why the elegant Peahen has adopted him as well.
Komuso has no name of his own, surrendering it when he gave up his sword for a flute, only Koyo remembers who he was before. And maybe Usagi; but the rabbit is even less likely to speak of it.
Aki is a fierce warrior, and proud protector of Koyo; it is often seen as odd that her closest friend should be the playful and mischievous Kitsune.
