NG707/Boruto Movie Unveil: The Villain

[Ensifer]

Must be the guy she was building a army for to fight against and whos the kid kneeling down? Blue hair and long sleeves

Mitsuki, a member of the new Team 7 alongside Sarada and Boruto, his origins is still unknown but he may be linked to the Otsutsuki Clan due to his odd name definition.

(His name means Full Moon.)

Mitsuki is the only one in the poster who has an annoyed look + Has taken a defensive pose. This tells me that Mitsuki is some how related to the movie villain.
