A nation of humanlike beings with fangs, tails, and fur wages a brutal war. In Mammalia, cultures collide and survival is forged in blood and steel as the largest war the Continent of Thalassara has ever seen tears nations apart. Towering mechanical combat suits stomp across battlefields, cities smolder, and thousands have already fallen.

This is an unflinching, anime-inspired, genre-blending adventure that follows soldiers, prisoners, refugees, and those still trying to live ordinary lives amid extraordinary violence. It mixes intense mecha warfare, the claustrophobia of captivity, the quiet courage of people in hiding, and bunches of light harem romance to explore a single, urgent question: how do you treat an enemy who barely looks like you?
