"A shinobi is to be sacrifice. If you are unwilling to sacrifice yourself, everything you have, for the sake of your village - then you are not a shinobi." - Saburo Mizuumi. Saburo Mizuumi (三郎湖, lit. Third Son Lake) was the forefather and creator of the Mizuumi Clan. He was famed for being an exceptionally skilled shinobi and his prowess with the Ice Release kekkei genkai has led many to recognize him as "Frozen Saburo". Despite his skill, he was killed early in life by a rival.
