Mamushi

Mamushi is a shinobi from Sunagakure and a teammate of Sana and Saya.

Anime debut: Naruto Shippuuden Episode #398

Personality:
Mamushi appears somewhat deranged, loving the notion of battling and violence. At the same time, he is very submissive before Saya, to the point where he refers to her as "Lady" (お嬢さま, Ojou-sama). Mamushi is also easily intimidated by her, as he shirks away, when she is enraged.

Abilities:
Mamushi seems to favour close and mid-range combat, fighting with long snakes he has hidden in his sleeve. The snakes are venomous, injecting paralysing venom in his opponents.

Mamushi, alongside his team, participated in the joint Chuunin Exams.
