Mothra: Queen of the Monsters (Mothra: Queen of the Monsters #4)

The twins' actions have brought Megaguirus to the present. Through a twist of fate, they realize that this action created a loop, and Megaguirus is actually responsible for weakening Mothra enough to perish at the hands of Antra.

Their new Mothra isn't even close to ready for her rematch against Megaguirus, so Emi and Mira hatch their most daring plan yet: train Mothra with a rematch against her killer - Antra. Will Mothra survive this deadly kaiju clash? And if she does, will it be enough to save the world?
