Three girls are captured and tied up together.

On the left is Sakura Kinomoto (木之本 桜). The middle one wearing bloomers is Nanoha Takamachi (高町 なのは). The one on the right is Natsumi Mizuki (水木夏み) from GetBackers (ゲットバッカーズ -奪還屋-). Although she is a teenager in the series, I drew her as a child here.
