Kōga just showed up out of the blue again, but now he is activating the Kōsai no chōsen. Otherwise known as the Challenge Of Mating. Where if Inuyasha loses he has to watch literally as Kōga mates with Kagome. He will have to win over the most points out of the four lords in six tests to save and mate with Kagome. To think he was just about to propose with a ring.

When Naraku kills all of her friends before being purified by Kagome herself, Kagome is willing to give up her own life to bring them back. But the Shikon no Tama has other ideas. Forcing her to give up her memories, her knowledge of walking and speech, her love for her friends, and her powers, Kagome is practically left as a child in an adult's body.
