Is Kagura Karatachi really Yagura's grandson?

Yes. The Boruto anime makes him the grandson of the Fourth Mizukage Yagura Karatachi. Note, however: this lineage is established by the anime, since Kagura is absent from the manga.

Is he one of the Seven Ninja Swordsmen of the Mist?

Not in the strict sense, and that is the classic trap. Chojuro personally chooses him as his successor and entrusts him with Hiramekarei, but he is not counted among the members of the historical formation. He was, however, part of the "new Seven Ninja Swordsmen of the Mist" of Shizuma, a self-proclaimed group of rebels who stole the blades.

In which arc does he meet Boruto, and is it in the manga?

In the anime only: the school trip arc in Kirigakure. There Kagura guides the Konoha class, beats Boruto effortlessly in a sword duel, then is manipulated by Shizuma Hoshigaki before breaking with him.

Does he become Mizukage?

No. Chojuro offers him his succession, but Kagura refuses it. He becomes his assistant, then warden of the Kirigakure prison, and his story ends in the anime-original arc devoted to the Funato Clan.

An Anime Character, Not a Manga One

One point to make right away: Kagura Karatachi is a character from the Boruto anime and the novels — he is absent from the manga. A chunin of Kirigakure, he appears in original arcs of the animated series.

Making that clear is not a detail: it places everything that follows in the anime canon, not in the written work of Ikemoto and Kishimoto.

Yagura's Grandson

Kagura is the grandson of Yagura Karatachi, the Fourth Mizukage — jinchuriki of Isobu and a figure of the Bloody Mist era.

The resemblance is striking: the same gray hair, the same eyes. A legacy that feels crushing, when you are descended from the man who embodied the village's darkest period.

Portrait of a young boy with ash-blond hair and pink eyes, a stitched scar under his right eye, bundled up in a green scarf — Yagura Karatachi, the Fourth Mizukage: Kagura inherited his light hair and pink eyes.

Hiramekarei and the Seven Ninja Swordsmen

The Mizukage Chojuro personally chooses him as his successor and entrusts him with Hiramekarei, the blade that can split into two swords.

Beware the shortcut: carrying a blade does not make him a member of the Seven Ninja Swordsmen of the Mist , the historical formation. He did, however, belong for a time to the " new Seven Ninja Swordsmen of the Mist " of Shizuma — a self-proclaimed group of rebels who stole the blades.

The Tragedy at the Academy

Here is the character's wound. As a child, during combat training at the Ninja Academy, Kagura falls into a trance and kills several of his classmates.

Shizuma, for his part, escapes with a long scar across his chest, taken while blocking a blow. Ever since, Kagura refuses to fight, terrified by what he carries inside him.

The Meeting with Boruto

Now the Mizukage's assistant, he refuses the succession that Chojuro offers him, and takes charge of the Kirigakure prison. His story ends in an original arc devoted to the Funato Clan.

In summary
