I'm So Powerful That I Die Young in Every Life

[Complete. Updates for the final few chapters are irregular. Sending love.] Thread starter: What should I do if I reincarnate in Teyvat over four hundred years ago? 1L (Thread starter): As the title says. 2L (Secret Master): What? You reincarnated too? 3L (Thread starter): I'm getting ready to reincarnate. 4L (Secret Master): Then my advice is to pick a good family to be born into. 5L: Is there a story behind that? 6L (Secret Master): Heh. You tell me. I reincarnated in Teyvat over four hundred years ago, in Inazuma, the land ruled by the Raiden Shogun. I was born into a famous and powerful family of the era. I was bright from a young age, topped the child prodigy rankings for years, and was the model child every other parent wished for, as well as the little demon king in every child's eyes. But unfortunately, I was born frail and wouldn't live to adulthood. It was too hard to endure days without a future, so I thought: I'll just live long enough to meet A-San. If I could see him just once, I'd be satisfied. Later, I got my wish and met him, but then I realized my desires didn't end there. I wanted to see him tomorrow, and the day after that, and keep seeing him forever. Even if I died, I'd become a ghost and haunt him! Distorted.jpg Unfortunately, I died anyway. Then I reincarnated again. I reincarnated in a world of jujutsu sorcerers. My childhood friend was a certain Six-Eyed Divine Child. I got the same life as in my previous life, and with no desire to live, I spoiled my childhood friend rotten. A Divine Child should have everything. Even if he wanted to destroy the whole world, he wouldn't be wrong. It's not like I'd live long enough to clean up after him anyway. Once can happen twice, and when I reincarnated for the third time, something went wrong. I turned to Dr. Mori standing beside me and said, "Make your debut, Dr. Mori." Mori: What did you say? I didn't hear you. Me: "As long as you act properly, I guarantee the whole of Yokohama... no, all of Japan will be safe and sound." Mori: ... · Note: Rina is strong. Very strong. Absurdly strong. Pairing: Yayoi/A-San/Scaramouche/Wanderer. A-San is called Yayoi in this story. Please keep that in mind. Any obsessive fans or haters, please stay away. I just want to enjoy my own meal. Thank you for understanding. This isn't set entirely in Teyvat, nor is it set entirely in any one anime world. The story will switch worlds frequently. Finally, there's no way everyone will stay in character! If anything seems out of character, please convince yourself otherwise! Sending love! Theme: Face life bravely, keep hope in your heart, and live positively
