Himesama "Goumon" no Jikan desu

As the commander of the Imperial Army's Third Legion, the Royal Empire's princess has led humanity to countless victories against the demonic Hellhorde. However, she has now been captured by the enemy and confined to the dungeons, with her sentient sword, Ex, as her only company.

Due to her royal status, the princess knows invaluable secrets that would help the Hellhorde achieve dominance. To have her reveal all the information they need, the demons do not hesitate to subject the princess to the most vile forms of torture—that is, tempting her with delicious food, lasting friendships, adorable animals, and the most enjoyable experiences imaginable.
