Beast Bond: The Nine-Tailed Fox Campus Belle

Reborn in the Apocalypse, I awaken as an SSS-rank Beastmaster from the Start! My ex-girlfriend publicly ditches me for an S-rank genius? Instead, I bond with a D-rank "useless" Fox Girl, and the whole school laughs at my poor judgment. Little did they know, my Beast Girl is actually a hidden SSS-rank Nine-Tailed Fox! Beginning with a bond, evolving three stages in three days! When the Beast Horde descends and the entire city betrays me, my Fox Girl has already evolved to Eight Tails. "Master, shall we destroy a city or slay Gods today?"
