Speaking of glider kunoichi in Shinrei Jusatsushi Taromaru, I realized that I have left The Gladiator and a few other games not introduced. Here's another 5 games:
1. The Gladiator (Shen Jian)
Created by the developer of Knights of Valor, this game comes with detailed art and good zako design. Two types of female zakos are present, one of which is glider archer who occasionally holds a banner aside from attacking. Another is swordswoman, a late game enemy who may not appear on every routine, which explains there are few screenshots of her online.

3. Guwange
Technically a shoot'em up/bullet hell, it has dancing girls with fans. First appear to guard stage 1 boss and die after enough damage is dealt, later a generic enemy on specific stage in which she will be knocked down before getting up and continues fighting. Shooting her repeatedly or in melee range may ensure a kill, but you can ignore her after incapacitating her for the first time, sparing her life. When she dies she will leave a pool of blood like other enemies.
There are other Cave games with female zakos, but I would like to pass due to time constraints.
