[Crossover] Getting Misunderstood Every Day

What do you do when you only have a few years left to live? Just try your best not to become a burden to your family, thought Kitahara Aki. She has the world's most devoted older brother. And a trash Main God who, despite his nasty sense of humor, takes extremely good care of her. By all rights, she should be the happiest person in the world. Only death is a shadow she can't shake. And now, she has a chance. The reliable adult Main God, Mr. Cat, tells her, [If you do this, you might be able to stay alive.] Kitahara Aki's eyes widen, and she asks him excitedly, "What do I have to do?" [, You can stay alive by turning into a cat.] Kitahara Aki: "..." Go die!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Trash Main God, you're doomed!!!!!!!!!!!!!!!!! The whole story's premise is right above ↑ The male lead is Hibari Kyoya. The protagonist's mission is to collect designated items from different worlds, and her cheat powers are ridiculously overpowered. Of course, you know some of those items can be a little... Anyway, this is a cheerful, cute little story. P.S. Not sure if anyone is still doing ranking raids, but I'm turning them down in advance qaq. I've discussed it with my dear Manor Master, and the story will go premium on December 10, 2017. There'll be a 10,000-character update then. Theme:
