Hey anon, this isn't from any aired episode as of yet, haven't seen the Boruto movie but doubt it is from there either. Most likely fan art, original artist is linked at the top of the page under "author"
hey Jokerboy, is this from an anime called "Dreamer"? closest i can find is Mahou Tsukai ni Taisetsu na Koto (japanese of course) but the characters dont look right...
Im pretty sure that this is an original piece of artwork not affiliated with any anime
