This is confirmed yuri, and the protagonist is a monster girl.
Mizunoe Ryu, the embodiment of the Earth's ley lines, is the first monster on Earth and the leader of Earth's monsters.
No one knows that Mizunoe Ryu, whose towering, mighty true form is 111 meters long, walks among humans as a 155-centimeter-tall blonde girl.
One day, she wakes to find that many strange and unfamiliar things have appeared on the planet where she was born, along with countless new dangers.
In the face of these threats, she will once again protect the fate of Earth.
So, do you believe in Mizunoe Ryu?
I really admire the first Earth to fight back against alien invaders.
Because you might run into Zogu.
Zogu, once I've finished cobbling together Gaia SV and Agul V2,
I'll scatter your ashes across the Pacific Ocean.
One last thing.
Earth is accelerating...
