Kaihou's turret-based magic reminds me of Axton and his upgradable turret from Borderlands 2 (notably the second cannon, additional rocket luncher and extra turret you can eventually unlock).

Kaihou's have the decisive tactical advantage of being self-propelled and repairable, which combined to her Regression Magic and their upgradable firepower makes her highly suited for drawn-out battles, weakening her foes and raining death upon them from multiple regenerative sources until victory is hers.
