- Torch the Franchise and Run: In retrospect, the author Akira Hiramoto may had hinted his intention to end the manga back in the 3rd story arc. Unlike most examples of this trope, no one was killed in the series, but the status quo was completely changed by featuring the destruction of the Prison. Not only that, the author abruptly ended all on-going plot threads and hastily concluded Kiyoshi and Andre's romance lives, with only the latter getting an Earn Your Happy Ending. What sealed the deal for this trope is that the author promised the fans a "much improved" epilogue when they purchase the final volume of the manga - It didn't conclude anything, and was clearly a waste of money for the fans who purchased it for the epilogue.
- Trolling Creator: With respect to that manga's ending. The final serialized chapter was released on December 2017 with an abrupt Downer Ending, with author Akira Hiramoto promising a "much improved" epilogue on the release of the final volume (April 2018). Fans eagerly waited four months only to find that this epilogue was nothing more than a few panels of the boys dreaming about the Wet T-Shirts Contest with neither background explanation nor conclusion.
