Extra Boss, Marisa Kirisame's theme, x2. A bit of of her theme from Shuusou Gyoku was snuck in, and is welcomed warmly. Actually, according to ZUN's comments, he was originally just going to arrange that, but instead we get another awesome theme. This arrange is just as awesome and that's really all there is to say on the matter.
