So I plowed through the Muenzuka and Garden Dungeons.
Is, uh, Komachi the only way to get Shinigami Scythe? Or whatever, because I heard she had a Blue Magic Satori can snag, like Iku and Mad Thunder.
Also. Holy hell was the Yuuka-Meddy double boss hard. Took me three or four tries to figure the pattern and gimmick out, the rest was up to luck, hoping Yuuka wouldn't go all USC-Modo.
Once I took her down, I was down to just Mokou and Satori. Mokou shortly kicked the bucket afterwards, but Meddy couldn't do anything to Satori due to Satori being specced for Poison Arts(And thus, immune to Poison). And the fact that she has a Gaea Ring equipped meant that Meddy was doing bugger-all in the way of damage, Satori's regen was clocking 15-30, meddy was barely scraping 9-20.
Just chucked a Crowbar on Mokou, stuck a few points in Axes, and capped Hourai, then let her autorevive do the work for me.
At that point, I could just hit autobattle, go off and make a sammich, and when I came back, she was down for the count.
EDIT: For context, I was around Lv26-28, with a team of Alice, Mokou, Byakuren, Satori, Sakuya, and with Sanae on commander.
EDIT 2: Is it a good idea to farm more than one Sexy Underwear for Byakuren? Because I noted it boosts Control/Charm chance by 25%, wanted to know if it's cumulative, or if it stacks.
