A place to call home is important to any young girl. For Nonoka Komiya, the first place she ever called home as a child was Lake Kiriya City, and she’s headed back.

The city is now split between folks who make money from saucer merchandise and those who don’t yet trust its presence. Things changed while Nonoka was gone; now it’s time to make sense of it all in CELESTIAL METHOD.
