Nanaly's big claim to fame is that she's a ridiculous "first pick" unit due to her skill being front-loaded--Triple & Quadra Shot don't scale with skill ranks worth a damn, but they're still strong enough that you can murder everything without first throwing a bunch of fairies in her direction. Throw in the Black tier initial skill timer and you have a unit that's uniquely suited to single-handedly carrying a crappy team past nasty early rushes through the magic of superior firepower. She's less dramatic on a veteran team that's already rocking Awakened plats but even then she's a nice pickup.
