Otomedius: Hope And Fate

A FanStory I'm creating for my fanmade game of Otomedius, the story can be different whatever you choose and can end differently.
The story follows after 3 years after of Otomedius X events, a new enemy, "Gygas" appaer, and even Gofer Sister want to know what called it, because Bacterion Empire and Gygas forces never have a good relationship, Gygas is attempting to steal an important core of Planet Gradius for his own causes, so the Angel Squadron alongside with newer integrants will have the neccesity to have a emergency alarm and do whatever is neccesary to stop Gygas before its plan can be completed.
