Work Hard to Be a Fairy in the World of Ladybug Reddy

Ni Die, a killer from the 21st century, accidentally traveled to the world of Ladybug Reddy. She has to constantly refresh her presence in order to survive in this other world. I really don't know how to write copy, so if you're interested, come in and take a look ( •̥́ ˍ •̀ू )~ (I'm not going to dismantle Ladycat. The heroine has CP but appears very late. I guess, anyone who has never seen Ladybug Reddy can understand it.) From now on, the heroine is called Isabella.
