Correction: Looks like I was wrong. According to Ayano, Teiya Ichiryūsai is yet another stage name. I guess we still don't know her real name. I've updated the pages appropriately.
It turns out that the voice actress for Krystal in the Japanese versions of Star Fox Assault and the cameos in Super Smash Bros. was using a stage name. Aya Hara's real name is Teiya Ichiryūsai, I recently found out. It looks like her revelation of her real name happened sometime in 2015. She appears to have largely left the video game voice acting industry and instead focuses on radio, narration, and announcement voice work. Amazing how you can still learn new things about subjects you thought were long over-with.
