Before he was able to get to Konoha, he was attacked and captured by the Three Ryūdōin Brothers. The eldest brother, Genshō Ryūdōin, took Yagura's appearance, and tried to get revenge on Guy for killing their father, but they failed. Yagura was later found by his fellow Konoha ninja.
The word "Yagura" (櫓 or 楼) means "tower" or "turret". It could also refer to the tombs in the middle ages.
