Lebah Raksasa - FFBE DV #19. 4 turns, 19.1b (No Summer Physalis/Karten/Angela/Nichol)

credits to Sinzar for his clear run, able to draft a team based off that.
I'm not sure if there's a way to perfect clear this fight without the conditional units. This is the best I could achieve for the time being, not perfect but close to that 20.4/5b cap. Any suggestions are welcomed to improve this fight/strat.
Siren has double water resist nodes to push yoshikiri to 300% water resist.
