Toki is... strange. But Sasuke doesn't necessarily dislike him? Sasuke's honestly used to a lot of odd people on accounts of many of the people he knows being transforming animals who are still learning human socialization, so in some ways he's kind of used to just... going along with whatever. He doesn't actually think Toki's a bad guy or anything, just kind of odd. He mostly hopes Toki's going to be okay, especially since it looks like things will be ramping up from here on out.
