Yu Qing is a long-haired calico cat with stubby little legs. One day, after pushing his servant's water glass off the table, he sprawled by the edge to admire the glittering shards and lazily swished his big, fluffy tail.
Suddenly, a large hand reached from behind and grabbed him by the scruff, lifting Yu Qing off the table.
"Hm? Has my sweetie been naughty again?"
The little calico hissed in displeasure, baring his snowy-white fangs and turning into a cat-snake.
How dare you, insolent servant! You dare defy your master!
This is your final warning. I'm a vicious villain, an evil overlord. I'm a heart-of-iron pork floss, seaweed, and cream cake, a cold-blooded, ruthless moldy slice of toast, a colorful glutinous rice ball who's killed countless people. I'm definitely not some silly little sweetie!
He was busy baring his claws and making a fearsome show of himself to the servant when a flash of white suddenly filled his vision, and a strange thing bound itself to him.
[I'm System 001. My scan indicates that the Host is a super-villainous kitty, perfectly suited to the quick transmigration bureau's villain-role assignments.]
Yu Qing thought this so-called System had excellent taste. He held his head high, proudly sticking out a neck he didn't actually have, and graciously agreed to the request.
In the worlds he entered, Yu Qing played the malicious cannon-fodder role to perfection. He was spoiled and bratty, bullied the protagonist shou, then went after the protagonist gong.
Yet despite how wicked Yu Qing was, every world he visited still fell apart.
The protagonist shou grabbed his wrist, eyes red. "You're the one who made the first move, Qingqing."
The protagonist gong stood in front of Yu Qing, gritting his teeth. "You said you liked me. Why are you talking to someone else?"
Some of the worlds include [The School Belle Who Bullies the Weak], [The Fiancee Who Calls Off the Engagement], and [The Warlock Who Brews Evil Potions]...
