Animal-eared Girl Era: Start by Forming a Contract with an SSS-Class School Belle

Monster Invasion, Blue Star's rules have changed, leading to a great turmoil in the world. Rules have descended, and human girls awaken with fierce beast templates, transforming into animal-eared girls who can summon fierce beasts alongside contracted boys.
There are all sorts of animal-eared girls like Pegasus, Flying Tiger, and White Snake.
Fluffy animal-eared girls, delicate animal-eared girls.
Xiao Ye awakens the God-level Beast Master System, which allows for unlimited contracting, the ability to detect others' templates, and rapidly enhance the forms of summoned beasts.

Xiao Ye is stunned, as he considered her a bro, yet she wants to be his wife!
Cheng Bingxi smiles sweetly: Take advantage of the overly shy deskmate and coax him into being a husband!
There's also the Nine-tailed Fox demon school beauty, Five-clawed Golden Dragon bearing girl, Soaring Kunpeng queen, and the Divine Beast Qilin empress.
Xiao Ye, looking at a nest full of SSS-tier animal-eared girls, expresses: Bring on more!
