Ningame

is a large red tortoise and Might Guy's personal summon. Ninkame watches over Rock Lee when Guy isn't around. He hasn't been seen since his first appearance in the series, but he is seen on the front cover of Volume 10. Ninkame is one of the few instances which indicates that Guy can use ninjutsu in the series (Ninkame is summoned off-screen, so Guy is not actually seen using ninjutsu).
