"Umi, come eat your canned food!" a girl's voice called.
The black cat curled up by the window slowly got to its feet, stretched out in a long, leisurely yawn, and ambled over to its bowl.
[Boss, let's teach those ungrateful cats in the east a lesson today!] a noisy voice rang in its mind.
[Be quiet. If you keep making a racket, I won't let you watch me play games today.] Umi primly licked the food from its bowl.
The voice in its head immediately fell silent.
The Tower suddenly appeared on Earth, and it took humanity a full sixty years to conquer the third floor. As the final boss of the ninth floor, Umi had its power squeezed out of it every day to keep the Tower running. It had no days off all year, and it was bored out of its mind.
At last, one day, it took the System monitoring it hostage and secretly slipped out of the Tower to Earth. It watched from the shadows and discovered that creatures called cats could have servants wait on them hand and foot without having to do a thing.
So it disguised itself as a black cat, got itself adopted by a kind girl, and smoothly settled into the retired life it had always dreamed of.
But the girl had a terminal illness. To protect the happy days they had together, Umi had no choice but to return to the instances and search everywhere for miraculous medicines.
Worse still, the girl's older brother was a high-level Hunter who went to dangerous places in the Tower every day. Umi had to keep an eye on him too, making sure he didn't get himself killed.
Who could have guessed that Umi's casual intervention would make its fame spread far and wide? Every Hunter was honored to catch a glimpse of the legendary "Cat God," and they even formed a huge Cat God fan club in its support.
Umi yawned lazily and thought, Retiring really isn't easy.
