In episode 26 of Boruto, we saw a new character named Kagura. He looks like Yagura so much.
Are they related?
Kagura Karatachi is a shinobi of Kirigakure, who works as an aide to the Sixth Mizukage. He is in line to become one of the seven swordsmen of the mist.
He looks like Yagura so much. Are they related?
Yes, Kagura is Yagura's grandson. Tsurushi Hachiya said so in episode 27 of the Boruto anime as he also mentioned that when Kagura drew his sword he became a different person and killed his classmates which Kagura obviously regrets.
