Lost Song Temporada 1 Episódio 3

The innkeepers sell out Rin, Al and Pony to some knights of the Capital Army. Pony attempts to stall them, but she is knocked out. Al then throws a Star Bomb, a type of firecracker bomb invention that can act as a smoke screen. However, Al gets stabbed by a dagger in the process, and Rin uses the Song of Healing to treat him. The knights promptly capture Rin, Al and Pony on boats. Al uses a knife to saw through his ropes before untying Rin and Pony. Also, Pony teaches Rin the Song of Wind. With Als Star Bombs and then Rins Song of Wind, the knights are successfully defeated.
