Chao to the rescue?
I am merely speculating. Negi, the White Wing, the Sport Girls, and Natsumi find themselves in deep trouble. How I won't explain in this thread. The only person who may be able to rescue them is Chao Lingsten herself.
After Chao had arrived back in her own time, she learns about what happen to Negi and the others. Chao will have to return to the past, in order to help Negi, and her classmates. How Cassie can return to the past is tricky. She will find a way to return to the past.
The only way which Chao can help Negi and the others is to used her time travel watch Cassiepeia. She can use the watch to return to the moment when Fate and his team destroy the Magic Gate. While Chao may not be able to stop the destruction of the gate, what she finds out is important.
I am trying to avoid why Negi, the White Wing, the Sport Girls, and Natsumi are in deep trouble. It is a spoiler. If Ken wants Chao to return, he has an excellent opportunity for her to return.
I am starting to see that you're a Chao fan takahata... but meh...
wouldn't she need a requirement to actually go back in time?
