This is the first boss where I can confidently say Kirin only is impossible, all because of the SP (Kirin just doesn't have enough air time without AC before the ground flames disappear). That said, no AC is very much possible. The scariest part of the fight is, ironically enough, phase 1. If Sistina is in either corner of the map and does the 6 bullet shot, jump away from the wall as high as possible, air up slash, and let your momentum dodge all bullets, just keep in mind not to go to the boss too quickly, or the last bullet will redirect and hit you. Her center placement is the one you want to avoid, as you will have to bounce off the wall several times, but it's still possible with enough precision. As for the other dangerous move, pay attention to how the 4 homing bullets settle in. The order the boss fired them in is the order they will launch at you, so be prepared to move accordingly. Phase 2 onwards is identical to the normal way of fighting Sistina, so the only different thing is dodging SP as GV by just jumping midair.
