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

Combat at 0:00. Step-by-step combat guide in description below.
Character set-up at 2:31.
Today, we take a detour from Beach Gensokyo into the land of Speed. Uhm, I didn't bother getting Relic Reimu just because... do you see how many Sun/Star answers I already have?? At least the stage isn't as annoying.
Thanks to Lady Shinki's guidance, we were able to clear this quite quickly. Also, help. Beach Yuyuko may be taking a break from eating meals with me... but that just means Lady Shinki has been occupying my time instead. Instead of eating sushi, she insists on showing me some Makai spells which can be fun.

Thanks for the strat, it works flawlessly. 1 thing to note (not really matter), turn 3 Flandre can only has up to 1.97p, not 2p, but it doesn't affect the result.
