Well, not really new. Keiko's Cyber Formula shenanigans were already introduced in the story. However, I believe they work better as their own separate story, and so I spun them off.

And so, Keiko makes her official debut as a Cyber Formula driver in the Tokyo qualifier race, but of course things are not straightforward as she isn't battling just other drivers, but also her own demons of the past.

I'm posting the Cyber Circuits spinoff on AO3 only. It is neater to navigate than my blog, and I plan on moving at least some of my old stuff to AO3 anyways.
