Black Killer Whale Baby

“Hey, mister!” One day, a small killer whale appeared before me. “Do you know where the educational institution is? I need to go there.” “You’ve taken a wrong turn, quite a ways back.” This seems to be my daughter. “What are you looking at, mister? Want a bite?” She doesn’t seem to know I’m her father. * * * …Is that what you thought I’d be thinking? If so, you’re dead wrong, old man! My name is Calypso. A fourth-time regression. While others live comfortably after being reincarnated into books, my life is ruined. To make matters worse, I’ve been reincarnated into a child-rearing story! In my third life, I faced a total annihilation ending! ‘You crazy male leads obsessed with this female protagonist!’ That’s right. For some reason, no matter what I do, I regress before reaching my 22nd birthday. However, in my third life, when the dragon went berserk and brought destruction, I accidentally discovered something. When a dragon goes berserk, it distorts dimensions! Could I use that to return to the home I used to live in? In my fourth regression, when I returned, I decided to use this dragon. Father? Brothers? They’re all just stepping stones to meet the dragon! “Wait for me, Lord Dragon!” [A female lead who’s tired of dying but has gone crazy from repeated regressions X A dragon duke bound by a mistaken contract with the imperial family / Child-rearing story / The female lead’s slightly insane family / Have you heard of survival of the fittest? / The strongest at the age of three / They think they’re a happy family raising children]
