10 Manga Artists Who Passed Away Before Finishing Their Works

Thread

Finding an anime without an ending is disappointing. Imagine if a famous manga writer, like Yoshihiro Togashi, took a break from Hunter x Hunter. Fans would hope he’d come back and wait for news.

But what if a writer couldn’t finish their story because they passed away? This has happened, and it’s sad for fans and the writer’s family. For many writers, finishing their story is a big dream.

Starting and finishing a manga can take many years. Manga writers work hard because they love what they do. But sometimes, a manga can’t be finished because the writer passes away.

When a writer passes away while still working, the manga is left unfinished. But fans still love and remember it.

Here’s a list of anime and manga that couldn’t be finished because their creators passed away. If you don’t want to feel sad about an unfinished story, maybe don’t read them. But if you’re curious, keep reading.
