Not sure if you've checked the wikia, but here's a tip

Do not attack any of the bosses when she is ready to NP. Switch the field type by hitting the other two bosses, this can reduce the NP dmg to a few hundred. This is easy to achieve during their first HP bar. When you break the bar each of them will benefit from two field types instead of one, just pay attention and check their buffs regularly to be sure who you need to hit next.

I focused on Nobu and Taiga, using UmU of coz(since both of them doesn't resist Arts card. And with proper buffs and Dmg up CE, UmU's buster cards can still damage Nobu). I had to used 1 CS to stun lock Jeanne at the end, and reset a few times.

It wasn't too difficult for me, probably i had good RNG since Taiga didn't Crit me too much or too hard. >_<
