Bio:
The eldest son of Minamoto no Yorimasa and the governor of Izu. He owned a famously swift and manageable horse named Konoshita which Kiyomori's second son, Munemori, asked to see, but Nakatsuna did not let him. In response, Munemori branded Konoshita with Nakatsuna's name, which was a great offense. Later, Kio, a Palace Guard and houseman of Yorimasa, borrowed Munemori's favorite horse named Silver. Kio took the horse to Nakatsuna who cut off Silver's tale and mane and branded the horse with Munemori's name.
Nakatsuna also joined Yorimasa's rebellion against Kiyomori. After they lost the battle, Nakatsuna is ambushed and injured, and commits seppuku.
