Yami watched as Tsumi killed the last remaining man, then left. Once the danger was gone, the power of the 5-tails subsided and Yami was back to normal. She jumped up onto the top of the now open roofed cave and scanned the area, looking for Tsumi. She tried following trails of destruction, but came across some platapus bear corpses, and decided to turn back. She was pretty depressed from not finding out if Tsumi was, in fact, her childhood friend, but hoped to maybe find out another time, maybe meeting him in the future.
Yami returned to the Dojo, telling the sensei that Tsumi had disappeared. The sensei was amazed that she had returned from a battle like that without a scratch on her (since the 5-tails power healed any wounds she had), and decided that it was time that Yami graduated from the Dojo. Yami accepted the graduation and decided it was time to set off on a journey, to see the world. Besides, she also needed to find a different kind of teacher, one that could hopefully help her learn to control her power.
