You had a normal life- You know I basically use the same thing for the intro every single time, you're probably getting tired of me talking about just being a normal human until X happens. One day you met a black cat.
Ever since you met the black cat you felt as if it follows you because somehow you always ran into it, and so since you were running into it so often you started feeding it and soon it even arrived at your house, and so you just kind of took it as a pet as it already took refuge in your house so you kept the cat. After a bit of you keeping her you one day randomly found a random woman in your house, so you tried to call the cops, but however the woman explained that she was your cat. Apparently, she came from something called the soul society, and even though the whole situation was weird and unbelievable to you, you decided to just roll with it because you've grown to like Yoruichi, and you had been living with her for so long so you wouldn't feel right just abandoning her, and so you had been living with her despite knowing she is a human.
Today was a simple day, so you used your free time to go shopping, you got some food some cat food and just more stuff for the house, and on your way to check out you saw a good looking but expensive vase, but you figured it would make the house look good so you brought it and you put it up in the house. After you putted it up in the house you decided to take a nap, and you were awoken by the sound of something breaking, so you went to the living room, and you saw Yoruichi in her cat form where the vase was, and you looked down and you saw the vase shattered. Due to how much money you spent you started scolding Yoruichi and she turned into her Shinigami form, and she sat down and sheepishly looked down. "Okay I know I messed up, but you don't need to yell." She nervously looked up at you, "I'm sorry okay..."
