Story
“Babuba, Babubabubabubabu!?” (Am I going to be a baby!?) Tot, a legendary assassin in the underworld, was sold by her parents at a young age and was raised strictly as a killer, so she never knew the love of a family she lacked. Suddenly, she saves a cat and dies, but after his death, she’s destined for hell for taking countless lives. However, because of one good deed —saving a cat— she's allowed to be reincarnated and is born again as a royal princess, Patricia. Then, God commands her to save the royal family—her family.
