The cumulative total of the previous comicalized series and the novel book version by Hibiki Kokonoe has exceeded 1.4 million copies (including the electronic version), and the blockbuster work has finally restarted! Futsu Sonoshin, who has a reputation for the cuteness and action of characters in "This is the result of a villainess who doesn't want to be ruined by all means", is a new "Potion" that will be handed over to the drawing and handed down. Please enjoy Kaoru's success as before. The new series will start with the "Siege Battle" episode that was interrupted in the previous comicalization! Kaoru and his party, who came to a hot spring trip in the mountains, are invited to the village by the village boys they met there. However, the village was threatened by a gang of well-known thieves. However, Kaoru doesn't like the villagers who tried to get him involved in the quarrel with the bandits like a trick...?

Her memories of being a military otaku in her previous life awaken and she remembers she’s in the world of an otome game she played in her previous life. And what’s more, she’s what people refer to as a ‘villainess’. In the game, the villainess is destined to face a destruction ending, but this girl is different. If you don’t want to be destroyed yourself, you have to destroy them first! In this way, our protagonist who is obsessed with recreating the power of modern weaponry using magical techniques by taking advantage of the magical talent bestowed upon the villainess, realizes it at last. The heroine? The prince? Shaming her family? Being exiled from the country? If only a bad end is destined for her, then she has to crush it through sheer firepower!
