It's not colored here, but it's described as a cyan chakra cloak with snakes protruding. Does it remind you of anyone? Also, take note of the unihorns in both chakra cloaks. This can't be a simple coincidence.

And while anything other than those allusions I made is merely speculative, there is also a little bit of a father-son scuffle in Naruto Gaiden: The Road Illuminated by the Full Moon between Orochimaru and Mitsuki because of Orochimaru's plan to set Mitsuki off into his own path. In that one-shot, Orochimaru refers to Boruto as the sun and Mitsuki as the moon, but if I'm not mistaken he only does so AFTER Mitsuki's left. He was not within earshot to hear all that and get that idea from Orochimaru. Only two possibilites are; he somehow programmed the goal of moving along Boruto in Mitsuki's brain, or Orochimaru's somehow in touch with Toneri and has made a deal with him to recruit Mitsuki as his subordinate. Both seem plausible (if not a little bit far fetched, with all the little info we have so far) but also both negate Mitsuki's quest to assert dominance in his one-shot. However, it doesn't seem out of character for Orochimaru to pull off something like that, so who knows.

But even if the person Mitsuki's working for is not Toneri, if that one-shot is to be taken seriously, he's not working with Orochimaru either since he chose a third option and refused to obey his commands. Who knows.
