I Want to Eat Your Pancreas

One day, I – a high schooler – found a paperback in the hospital. The “Disease Coexistence Journal” was its title. It was a diary that my classmate, Sakura Yamauchi, had written in secret. Inside, it was written that due to her pancreatic disease, her days were numbered. And thus, I coincidentally went from Just-a-Classmate to a Secret-Knowing-Classmate. It was as if I were being drawn to her, who was my polar opposite. However, the world presented the girl that was already suffering from an illness with an equally cruel reality…

Don't be fooled by the ambiguous title, just read the 1st chapter (not prologue) before you decide on anything else.

I just read till the lastest TLed chapter in one go and I'm still feeling it... Moved, stirred, as though my heart has been lured in by the fragrance of a hook the novel threw. The throbbing that aches from being caught on the hook yet irresistibly so.

Hats off to the translator for working on such a deep and intricate novel, I'm sure it was hard work to bring forth the... more>> subtle feelings between the lines. It also makes me want to read the novel in Japanese to get a feel of how the conversations actually flowed...


Not recommended for those who want to stay faint-hearted.

Alas, the prologue spoilt some of the enjoyment of the story for me. I would strongly advise against reading chapter 0 unless you want to know how it ends (though I haven't read till the last chapter).

Quite sweet and interesting. Honestly a beautiful piece. Left me wanting for more. The translation quality is perfect. I saw no grammatical errors at all. The sentence structure is also on point.

If you're looking for something more serious, like a novel, this is something you might like to try.

Literally made an account to rate this. Really loved this novel. Very good storytelling, told through the thoughts of one side and action of both. Brings a lot of life to the characters. Slow and sweet, words cant describe how much I enjoyed it, thx for the ride author.

I can't recommend this novel enough. It's an incredibly moving tale of a boy who has no care for those around him meeting a girl whose life revolves around interactions with other people. The chapters are slow but highlight the details in every one of their interactions, and those small details are what makes reading the novel such a breathtaking experience. Every word in the novel is meaningful and every sentence said by the two lovely characters contribute to the beauty of the plot. The ending is pre-determined because of... more>> the girl's illness, but the way the author (and the amazing translator) executes it sends a rush of emotions into my heart every time I re-read it. I wouldn't say that it's a sad ending, though, so I would still recommend this novel to those who shy away from sad stories. It's truly a wonderful read that will influence future readers to re-evaluate their perceptions on life and what it means to live. <<less

no this is not about cannibals and there are no Hannibal Lector type characters. A sad, sweet and thought provoking novel with a very good translation. I came here after watching the movie and I didn't know it had an anime as well, I might check it out (the book is better, but then, it usually is).

Stop! Please stop my tears. I was just sitting in the corner balling my eyes and freaking my mother out. They just wouldn't stop comingggg.

*sniffles* Anyhow, this book was fantastic with 10 chapters that were long. I really could put myself in the protagonist's shoes, especially his love for books. The thing that got me was the beautiful platonic relationship between the MC and the FL (?). Pure friendship between people of opposite genders need to be emphasized more! This marvelously displayed it.

In my humble opinion, this book did a... more>> beautiful job of portraying the feelings of the MC and how relatable he is.

The fact that he didn't go to her funeral was all the more perfect. It was him and it would have also been me in those circumstances.


At moments in the beginning I found the FL annoying to the point I didn't understand how he tolerated her, but there was beautiful character development that stole ma heart.

Finally, her

death was perfectly executed.

The author had a clear of vision of the theme for his novel and wrote it in, seamlessly emphasizing it. This couldn't have been better. I was shocked and upset and wanted to hurl my meal, but it was just the right thing for the novel. It was satisfying.

In the future, my metric for friendship is going to depend on how much I wanna eat their pancreas. <<less

I read the book in Japanese and definitely enjoyed it.

However, I did reference the translation here a few times while reading and noticed that the translation unfortunately does have errors particularly during conversation e.g. One example in c2: お洒落 has to do with being fashionable, not drowning in alcohol (the conversation is reshaped to fit the mistranslation).

Praise to the translator for making the novel more accessible to interested readers, but I'd recommend reading the official translation if possible.

Note I read the official translated version.

Probably still my favorite story. I've read the LN, manga, and watched both movies (Live action and anime). I think I shed tears still everytime I read/watch any version. The blossoming friendship between the MCs and how it builds to a really raw emotional peak was very satisfying if not still sad.

There is an epilogue story that continued a bit in the future was good for some extra closure.

In all I'd recommend this in all mediums its available in. I think I'd rank them... more>> LN>Anime>Manga>Live-Action <<less
