As the Little Sister, I Keep Getting Eaten

Shimajou Chika is a high school student who leads an ordinary high school life, just like any other average girl. Sometimes, being ordinary is a kind of happiness, isn't it? But one day, that life suddenly came to an end. An accident cut her life short at the age of seventeen. After her death, Shimajou Chika was told by a guide in the pure white world of the dead that in her next life, she would be reincarnated as a mosquito-eating bat. A bat! She'd rather be Batman. At least he'd still be human! While she was still in shock, she was told she could either be reborn as an animal or start over in a manga world. If that's the choice, of course she'd rather be human. But manga worlds are full of danger. Dying is one thing, but why does she have to get eaten too?! First world [The Promised Neverland. This time, she was reborn with a clever biological older brother, a kind mother, and a bunch of adorable siblings. The ending: shipped out, GG.] Second world [Hunter x Hunter. This time, she was reborn with handsome, interesting older brothers and a bunch of adorable younger brothers. Her family was close, kind, and hardworking. The ending: eaten by ants, GG.] Third world [Demon Slayer. This time, she had a gentle older sister and a dim-witted older brother. Her gentle sister died in an accident, but her brother raised her with great difficulty. The ending: eaten by a demon, GG.] Why?! Why do I always get eaten when I'm the little sister?! (Furious) The worlds may not appear in this order. The ending will always involve being eaten by a nonhuman. Three worlds are planned for now, but more may be added. This is the initial blurb and may be revised later, but the story won't change. The pairing is undecided for now. We'll see. [Reader's Guide] 1. OOC warning. The story's setting is based on the Japanese drama Brush Up Life, but it isn't very relevant and won't affect your enjoyment. 2. Please don't mention my story under other people's works, but feel free to recommend other stories under mine. I'm hungry for content too. 3. If you don't like it, please quietly leave without telling me. I'll cry. 4. If there are any other worlds you'd like to read about, feel free to recommend them in the comments. Theme: Saving a life is worth more than building a seven-story pagoda.
