Reborn Seven Days Before the Apocalypse, I Stockpile with My Cat and Go on a Rampage

This is an apocalyptic revenge power fantasy starring a beloved cat:

The ultimate thrill of stockpiling supplies in a pocket dimension,

the bloody satisfaction of tearing apart a cheating scumbag and his shameless mistress,

the bond between a person and their adorable pet, serving as each other's armor amid waves of zombies,

and the flames of survival rekindled atop the ruins.

Are you ready to face the apocalypse?
