New Seven Ninja Swordsmen

The were the self-proclaimed successors of the original Seven Ninja Swordsmen of the Mist. Formed by Shizuma Hoshigaki, the group's objective was to start a coup d'état in Kirigakure to overthrow the Sixth Mizukage and replace him with Kagura Karatachi, as well as return the village to the era of the "Bloody Mist".

History
At some point during the Sixth Mizukage's era, Shizuma gained support from people connected to the Water Daimyō to start a revolution in Kiri. Upon Kagura obtaining the key to the vault containing the Seven Mist Blades, the group confronts Kagura at the Kirigakure Academy. There, Shizuma manipulates Kagura into joining his group and uses the key to get into the vault. With each member taking up a weapon, they intend to start their revolution by destroying Kiri's Memorial Park, but are stopped by Boruto Uzumaki, who is accompanied by Sarada Uchiha and Chōjūrō. Ultimately, the rogue group was defeated and their rebellion stopped before it could actually begin, being written off as "just a scuffle among kids". Afterwards, the group's original members were imprisoned in a correction centre to undergo rehabilitation.

Some time after the coup, Shizuma escaped his confinement with the help of Hassaku and Ichirōta, the result of which caused the two to be re-located to different security facilities. The other three members that stayed at the original location were later assembled again by Kagura.
