I'm betting on Yuka and Mima, but I'm also thinking we get more of a fight than everyone is expecting. Maybe.... 15+ pages, not counting unrelated points?
Thinking back, Reimu and Yuyuko didn't really do much in this battle, aside from maybe one spellcard each. If anything, this is just a sign that tricks and strategy won't work if your enemy is just that freaking powerful.
This. A nice example is the PC-98 games and how they're practically unknown to anyone just getting into the fandom. And the thing about licensing and him losing Touhou could also be true. Look at Mima... we'll never see her in official works no matter how much anyone wants to speculate for Th13. She's owned half and half by ZUN and the company that helped him produced the PC-98 series. He can't use her.
