[Reborn!] How Could the Manga Have a Bad Ending?

Fierce, blood-pumping battles, a legendary middle schooler saving the world, and innocent romance. This is all just the setup for a shonen manga, right? Recently, Tianshui Lizhi discovered that an absurd story straight out of a shonen manga was unfolding around him. One of his childhood friends runs around naked, bursts into flames, and flies through the sky. Another raises a tonfa and beats up everyone in Namimori. And yet another, who was supposed to be a baseball ace, has somehow become a swordsmanship master? And all of this is because a little baby showed up. Could this be some kind of strange plot switch? He'd been wanting to draw a manga lately but couldn't think of any ideas. This is perfect, it practically fell right into his lap! Of course, listen to me, I absolutely will not draw anything inappropriate! He thought things would stay lively and fun from then on. But one day in the future, just as Sawada Tsunayoshi was about to tell Tianshui Lizhi everything, he was suddenly killed by a rival family. It was all like a dream. Everything had been at its best, and then, one by one, everyone suddenly disappeared right before his eyes. A mischievous and heartless god cheerfully urged him to start a cycle of reincarnation and save them. Fine, he would save them. But why did it feel like... like it would never end? Cycle after cycle, Tianshui Lizhi gradually grew up. Watching his friends die again and again drove him to the brink of collapse. To stay together with everyone, he would make it to the end of this cycle, even if it meant starting over a hundred times! OOC warning! The protagonist starts out as a pretty, clueless idiot. He loves drawing manga, dreams of becoming an excellent manga artist, and has a gentle personality. A group-adored protagonist, an open ending, and everyone loves the little idiot. The protagonist grows over the course of the story, and the romance routes begin right from the start. If you're possessive, don't read this, because there will be lots of romance! The protagonist is pretty scummy too, but he only moves on to someone new after a breakup. After maxing out everyone's affection in the early chapters, the story enters its cycle of reincarnation. Things get more angsty from there. There will also be all kinds of ways for characters to die. It's not just A Gang and the others who die, the protagonist also dies and starts over. (There may be crossovers with some other anime, but they will make up only a small part of the story. The main focus is Katekyo Hitman Reborn.) Theme: Rescue this absurd plot
