Peony may have come in second place on the mega popular cooking show Space Battle Lunchtime, but with a girlfriend and a royal catering gig for a space empress, she's on top of the world--until she finds out her old rival Melonhead is catering the same event.

What she hasn't dealt with is her girlfriend Neptunia's mysterious past, which comes to a head when Nep's sister turns out to be the empress's bodyguard.
