When the Blue Star's rules shifted during the Monster Invasion, human girls awakened with fierce beast templates, becoming animal-eared beauties capable of summoning powerful creatures alongside their contracted partners. From graceful Pegasus maidens to mystical White Snake enchantresses, each girl possessed unique abilities tied to their beast forms.

Surrounded by an entire collection of SSS-tier animal-eared girls, each more captivating than the last, Xiao Ye embraces the chaos with a single declaration: Bring on more!
