[Touhou LostWord] vs L1 Eiki DS - Lv120 clear!

Combat at 0:00. Character set-up at 2:07. See description below for more info on this comp.
My Youmu wanted a rematch against Eiki and her crew, so she recruited Lady Yuyuko, Lady Yuyuko, herself from another universe, and her best friend Koishi. And of course, Lady Yuyuko brought more sushi for me to eat with her... Okay I'll sit on your lap, Miss Yuyuko...
P.S. Some people didn't like the way I was formatting story card info, so I'm trying a neater (but longer) approach. Let me know if you like this way of formatting story card info or my usual way. Thank you.
