Small easter egg: The problem on the board was similar to that in the Chunin Exams: A ninja sits in a tree: how far can they throw a kunai. apparently the second, more complicated part included throwing it upwards and adding wind resistance (judging by Mitsuki's comments).

Mitsuki is definitely very interesting. Oh and judging by the teaser, it seems the dark chakra comes from the chimera creature.
