I am looking for a manga (it's not "level up by eating").

The MC is a young man. He's in love with his childhood friend. She was in the hero's party. When she came back from her adventure, the MC sees her next to the hero and he thinks his friend and the hero are in love (it's a mistake) Well.. he's extremely sad, so, he runs away. He goes to a forest or mountain... He lives there alone... he eats what he can eat to survive... a lot of strange food... he's sick, but each times, he grows stronger and stronger. At some point, he's not a human anymore.

Others things :

  • his sister is looking for him
  • there is a dragon in the story (later)

It's something I read on a website so it's probably a manga (Japanese translated in English). I don't think it was a manhwa (Korean comic) but maybe I am wrong.

  • Hello Seb. Can you remember anything else; the year, the format (film, short story, comic book) the language it was presented in etc.. Check out our story ID checklist. Also please take our tour and refer to the help center for guidance to our ways. Nov 3, 2021 at 20:28
  • Please edit your question with any additional details you remember rather than adding those details in the comments.

1 Answer 1


I am fairly sure this sounds exactly like Sono Mono Nochi Ni… (WN) It appears it was rebooted though. (from Sono Mono. Nochi ni... to Sono Mono. Nochi ni... (NARIIE Shinichirou)

Pretty sure this is exactly what you are looking for. However, from what I can tell anyways, the mistake is not a mistake. Might be wrong on that though.

99.99% sure this is it though. Enjoy either way.

Description of Works / Preservation Data

[First Link:]

  • Site "novelupdates.com" is an info listing of thousands of light novels. If it's been published officially then it is most likely listed on this site. (fan novels, or wip things on forums are typically not included)
  • The novel of "Sono Mono Nichi ni" (this is also the source the manga draws upon.)
  • It follows Wazu, who was an ordinary townsman. (The Main Character, and the Protagonist)
  • He's in love with someone, they promise to marry while children. Later on his love returns but she is now fated to marry someone else. Wazu takes this terribly and runs away from his life to live in mountains for two years. During these years typical light novel tropes such as eating mysterious things that increase the protaganists power occur. Eventually he can basically one-hit KO a dragon.

[Second Link:]

  • This is the initial manga adaptation of the novel. It was serialized in Comic Earth Star (magazine) and published originally by Earth Star Entertainment. Art by AYANO Urasuke. Supposedly one volume was completed before it was dropped. This follows the same story as the novel.

[Third Link:]

  • Site "mangaupdates.com" is basically a wiki of manga and their various fan translations.
  • This is the rebooted manga adaptation. Published and serialized by the same entities as the first iteration. Art now done by NARIIE Shinichirou.
  • The current manga reboot. It, also, follows the story of the novel.
  • twenty-four chapters have been fan-translated as of now.
  • 4 volumes are completed in original language and ongoing.

    Hi, welcome to SF&F. Could you please describe the work(s) at the end of those links so that all the relevant information is in this post? (And in case of potential link rot.)

    @DavidW Is that good? I think that's the most relevant information at least. I would have put it in a collapsing text box or something but I could not figure out how to do so.

  • I wanted to just somehow make it appear on hover of the link, however, that doesn't seem possible (in a way that doesnt look terrible). Hopefully this is good, if not perhaps someone more knowledgeable can let me know of a better method.
