Because Naruto is an action anime. Genjutso just isn't that action-packed, usually.
Heh. Seems like you're enjoying yourself a bit on this mission Sasuke. Doing something for others, and not just your revenge as is your typical seems to be a good thing for you. I'm glad to see you grow so fast. Apologies for not speaking up in the earlier burst, I was... indisposed of, for a time.
Now though, I am glad to have returned. As for your comment earlier about the strangeness of that wolf I sent to you, with the music? It's not really a wolf, but a divine avatar of a goddess. Specifically, Amaterasu, Goddess of the Sun. Though, it seems like it can grant you a power, when you are ready to receive it. Specifically, the power to produce black flames that can burn through near anything, except highly chakra-infused materials. That includes other fire. It burns itself out after 7 days and nights, and only the one who started the fire can extinguish it. To use it, both the Sharingan and Mangekyō Sharingan must be unlocked first. Which may not ever happen, honestly.
By the way Sasuke? May I ask you what you think of this song?
