>We're more powerful than Yukari, though; she told us that back when Shinki removed our ribbon for the first time. We just don't have the gaphax she does.
> What she said is that she couldn't manipulate the border of insanity too long, since the insanity was tied to your power, insanity was more or less your power source. While you may have more brute force than Yukari, you do not doubt that Yukari would win, partially because she's far smarter than you, and mostly because of her boundry manipulation. Indeed, you doubt Yukari is very good in a fist-fight at all... but she doesn't need to be. In addition, you were technically semi-in Makai, and Shinki's presence wasn't helping.
> You also know Yukari is plain unfair in danmaku, from what Reimu has told you. Apparently it took Reimu, Marisa, and Sakuya together to defeat Yukari when she was just fooling around and copying Ran's spells.
> Indeed, you have confirmation you can't beat Yukari, because she was the one who beat your insane self and sealed you in the first place.
>"Hmm...Ah, you picked up earth magic, right? I just had an idea I wanted to test, and figured a stone pillar would be the perfect target."
> "Well, earth magic was already in Patchouli's 'seven days of magic'. My magic is the 'Four Corners', Fire, Earth, Water, and Air." Daiyousei says, before she sighs "I'm still attempting to figure out what the 'Centre' magic of my square is. Like Patchouli's 'Week' has Sun and Moon, the 'weekend magic' that one can only learn upon mastering the five 'weekdays'."
