MoC 12-2 A Song's True Theme 2.2 0 cycle ft. E6 Gallagher, E0S0 Firefly, E6 HMC, E0S0 Ruan Mei

I can't believe I actually did it aaaaaa. After a bunch of relic switching because my Firefly was a bit too fast for HMC when I got her 4-pc Cavalry, which kinda ruined my Ruan Mei's 160 BE.
And the fact that I have to only use Firefly's enhanced skill once against Past, Present and Eternal Show.
