勇者の俺を使い潰すつもりだった裏切り者達を土壇場で見限ってみた

Every member of the hero’s party, including my childhood sweetheart, had been seduced by that tr*shy prince!!

—So, right at the critical moment when victory against the Demon Lord was certain, I flipped the script and got my sweet revenge on them, lololol. What? The revived Demon Lord’s army is attacking the kingdom? And without me, the hero, it’s just going to be a one-sided massacre?

Not my problem!!! Is there some insurance you can buy at this point? Yeah, right, lol. So, go ahead and die already.
