Isekai De Pension Hajimemashita. Sekai De Yuiitsu No Kuro Majo Desu Ga, Kono Chikara Wa Okyaku-Sama No Tame Ni Tsukaimasu

I lost my life in a fire at my workplace and found myself reborn in another world. My name in this life is Lunan. According to my black cat master, I am a "black witch" and have the power to change the fate of the world. But I have a dream that I want to fulfill more than that. Yes, I want to run a "pension" where any guest can rest in peace! A fantasy of hospitality in a different world, depicting interactions with fluffy guests!
