Konohamaru is Boruto, Sarada, and Mitsuki's sensei, so he wont be the one teaching them. Mirai is only a Chunin, and is only a few years older than them, she is way too young to be their leader, she isn't even a Jonin yet. Their sensei will likely be a brand new Sarutobi Clan member we never met before.
