It's not Umi's fault, i don't know if you guys have heard, but the kendo armors... stink XD
As some one who did kendo i can tell you it's a paticular smell, the armors juste absorbs your sweat and transforms it into some thing else. And worst thing is that it's hard to wash out, it can remain in your hair after you shampooed once. That's one thing i won't miss about kendo. XD
