Summary
A sweet little series set in a world where monsters had been captured from the beginning instead of shoved underground.
Eventually, as the years and generations pass, both humans and monsters slowly forget the monsters were ever free.
We follow the story of an aging little zoo hoping to expand and take in a few monster pups. And the stories of several monsters who find themselves being transferred to the place.

Summary
Ink is killed, one day, somewhere in the multiverse.
He returns a month later and life continues.
Two years later, Dream is mortally wounded in battle, leading to an imbalance between good and evil. Blue is in too deep, Nightmare is reaping the results of his actions, Error isn’t acting quite right. Morality stops being black and white as lines start to blur. A deeper force begins to seep into the constant battles, exposing the multiverse's rotting core and foreshadowing an era of darkness, the likes of which haven't been experienced since the X-event.
Ink was killed, once, planting the seeds of something greater than he could have ever imagined, and bringing him closer to the one person he never thought he'd truly understand.

Summary
Error wakes up in a game he never chose to play—Until The Last Breath, a brutal survival world hidden between life and death. The only players? People trapped in comas. The only way out? Win.
To survive, he must fight through deadly floors, forge uneasy alliances, and follow three unbreakable rules:
[ 1. GAME OVER means death, both in-game and in real life. ]
[ 2. Artifacts must be crafted from Fragments found throughout the world by a Player. ]
[ 3. Reach the final floor before the chronometer runs out… or fade away forever. ]
There are no second chances. No resets. Just one question: can Error and his team beat the game before it beats them—and can love survive in a world designed to tear everything away?
