@Namikaze I'm fairly certain he did. The chakra around him just matches with how his Sage Mode looks. It's definitely foreshadowing his hidden trump card.

I don't think it's just him releasing his chakra. It's just seldom shown and I think it's just more likely he was entering his Sage Mode, as Shino would honestly probably be too powerful for base Mitsuki. I'm fairly certain, from what we've seen he was capable of during the war, he could've killed Mitsuki if he used some of his deadlier techniques.

Also note the scenery, it's just utterly annihilated. Some Jounin-level combat right there.
