High school student Amatsuki Iori was summoned to a different world to fight as a brave of salvation, but whilst he was trying to save the world, he ends up being killed by the companions whom he wholeheartly believed in.
It was then, when Iori thought that he already died, he came to his senses only to find that he was re-summoned to the same world, but in the future.
Back again as a brave to subjugate the demon king which his former self had failed to defeat previously…
Then, he noticed, that among the guys who ordered him to fight as a brave, the figure of one of his former comrades could be seen.
「……I will make you regret having betrayed me.」
A girl then appears before him as he is consumed by hatred, but not any ordinary girl – she is the former demon king who is also aiming to take revenge.
The brave man who abandoned his heroic ideals, exchanging them for a burning desire to take revenge and the former demon king who seems ready to join him in his new-found quest.



While I don't think it needs to become as chaotic as Nidome No Yuusha, it suffers from a lack of substance. Most plotlines come across as a comedy, with moments where the protagonist talks about violent actions, only to revert back to a comedic tone. I use "comedy" loosely here, as it's rather dry and unoriginal, resembling a collection of clichéd isekai jokes. It's not terrible, but it doesn't stand out either. After a few chapters, you can predict the formula.
I genuinely tried to find something engaging, but alas, nothing really grabbed me. Even the skills, magic, and items are unremarkable. I wouldn't call it a bad read, but giving it a 3/5 feels generous. It's passable if you're looking for a quick read with no other options, but that's about it.
1. The main character's motivation isn't a typical revenge plot; he seeks understanding rather than retribution. While some betrayals do lead to a more complex revenge, the focus is on the why, not gratuitous violence.
2. The protagonist remains理智, employing reasonable strategies rather than becoming unhinged or overly aggressive. He's relatable without being overly powerful or reckless.
3. Unlike 'Nidome no Yuusha,' this story stands on its own, despite a slight resemblance. It offers a fresh take on the genre.
4. I appreciate that the narrative avoids excessive gore and a mentally unstable protagonist, which was a relief from other revenge stories.
5. The main character is portrayed as a likable and decent person.
6. However, the manga adaptation falls short of my expectations. It fails to live up to the potential I had when starting to read it.
7. The protagonist's growth is realistic, focusing on accumulating power to match his past self and seeking revenge on select individuals.
8. The female lead, a gluttonous demon, genuinely cares for the MC, and their shared goal of revenge against certain targets aligns their interests.
9. The targets of revenge can be likened to mid-level bosses in RPGs, adding depth to the narrative.
That's a concise summary of what I like about the story.
