Bayonetta (SSBU)/Back aerial
A high-angle back kick. Based on the second hit of Bayonetta's aerial Punch + Kick (PK) combo while wielding Love is Blue. The Bullet Arts version of this move fires one gun behind her at an upward angle. It is slow for a back aerial (frame 11), but acts as Bayonetta's strongest aerial KO option outside of combos. Some aerial combos can lead into back aerial for additional damage, or act as KO combos (including from up tilt). Its hitbox is rather misleading due to her attack's motion trails.
The bullet is shot from Bayonetta's left leg gun.
Up to 10 consecutive bullets can be fired by holding the button, with each one adding 7 frames to the move's duration. Otherwise, the Bullet Arts extension lasts 11 frames.
