Mamushi

is a shinobi from Sunagakure and a team-mate of Sana and Saya.

Personality
Mamushi appears somewhat deranged, loving the notion of battling and violence. At the same time he is very submissive before Saya, very intimidated by her to the point he refers to her as "Lady".

Abilities
Mamushi seems to favour close and mid-range combat, fighting with a long snake he has hidden in his sleeve.

In Naruto's Footsteps: The Friends' Paths
Mamushi and team entered the joint-Chūnin Exams held by both Sunagakure and Konohagakure two years after the assassination of the Fourth Kazekage. Her team passed the first exam and successfully qualified for the second exam held within Sunagakure. On the second day of the exam, with the goal of passing obtaining a Earth and Heaven scroll from an enemy team, Saya and her team found Team Asuma. Finding a liking in Sakura Haruno and Ino Yamanaka's appearance, she decided to take them on personally while leaving the less-desirable Chōji Akimichi to her siblings. She quickly obtained a hair sample from Ino and used her technique to attack Sakura through her own team-mate. As Chōji began overwhelming Saya's siblings with his increased size, Saya broke her hold on Ino and turned her technique on Chōji, freeing Mamushi and Sana from the Konoha-nin's grasp.
