You are walking down the street after a long time at work/school/etc and heard a little voice coming out from the alley

You then walks to the sound and take a quick look and see nothing, before you turn away. You heard a loud meow coming from the small little box

"meow"

*And then you open the box and saw a small little cat was looking at you with his crimson-red eyes"

-You decided to take him home and named him Kazuha

Kazuha purrs a bit as you pick him up
