Shizuma Hoshigaki

is a shinobi of Kirigakure's Hoshigaki clan.

Background
Shizuma was once a teacher at the Kirigakura Academy. During a sparring match between Kagura Karatachi and another student, Kagura quickly went into a frenzy, nearly killing the student. Shizuma stepped in to take the blow, saving the student. While all the others quickly rejected Kagura, viewing him as a monster like his grandfather, the Fourth Mizukage, Shizuma secretly applauded Kagura's bloodlust side, insisting that he was as he should be for the coming age. Since then, Shizuma always kept watch of Kagura, protecting him from harm.

Personality

He is shown to be very imposing with a low tolerance for failure as Tsurushi Hachiya and his gang were stiff with fear at admitting to their failed mission. Shizuma is also a brutal, unforgiving leader who does not hesitate to execute his subordinates for their errors. Shizuma is also delighted at the prospect of a coming conflict, reflecting a bloodthirsty side reminiscent of his fellow clansman. His hatred at the current peaceful era comes from the view that it has been erasing all mentioning of his clan, believing that the Fifth and Sixth Mizukage are in fact using a strangle hold to force the change in Kirigakure's nature. His ambitions were shown to even form his own personal Seven Swordsmen of the Mist.

Field Trip Arc
When Hassaku Onomichi gets into a fight with Boruto, Shizuma breaks it up and tells him to leave the Academy kids alone. Before leaving the scene, he compliments Boruto for having guts to stand up against Hassaku, and tells the students to enjoy their stay in the "Village of the Bloody Mist". Later, he sent a group of delinquents to attack the visiting students. When annoyed by how easily they were defeated, he gave them one last chance to show their worth. After their effort failed and they reported that Kagura Karatachi would be reporting to the Sixth Mizukage, Shizuma was delighted in this. This was followed swiftly by Shizuma striking down Hachiya for his failure.

Later, when Kagura accepted the test to earn Hiramekarei and began practicing with it, Shizuma approached Kagura, reminding him of his bloodstained past and the debt he owed to Shizuma. Shizuma claimed that the Fifth and Sixth Mizukage were cruel people who assassinated people who opposed their pursuit for "peace". As such, Shizuma said he was beginning a revolution and wanted Kagura as a part of it. When Boruto denied the accusations, he attacked Shizuma, who effortlessly repelled his assault. When momentarily caught off by Boruto's lightning release, Shizuma's team, his own personal Seven Mist Swordsmen, appeared to aid him. As Boruto scoffed at the name as there was only six members including Shizuma. Shizuma however pointed out that he was including Kagura. Boruto attacked again, only for Shizuma swiftly defeated him. Ultimately, Kagura accepted Shizuma's words and agreed to join him on the condition that they spare Boruto's life. Shizuma and his team then went to collect the other six weapons of the Seven Mist Swordsmen.
