Chen

was a legendary taijutsu master from Konohagakure.

Background
Chen was known as a legendary hero in Konoha. He once had a student much like Rock Lee who was unable to perform ninjutsu and dedicated himself to become a taijutsu master. Both Chen and his student participated in the Third Shinobi World War, with the latter killed in the war due to his inability to learn ninjutsu. The death of his student greatly affected Chen and the shinobi faked his death and gave up being a shinobi. Years after, his granddaughter Akami would occasionally leave rice balls for her grandfather, aware that he was still alive.
