Trinity x Calamity: Midara na Shitsuke to Owaru Sekai

The world was on the brink of destruction, about to meet its end at the hands of angels who were fulfilling a prophecy of the 「apocalypse」. Some lamented, some gave up, and others simply waited for the end.

However, there were also those who resisted the 「apocalypse」. One of them was the Demon Queen, Anneliese, who rose to fight the angels.

Victor, the hero who serves her, Sophie, an overconfident half-elf witch, and Ulrica, a free-spirited wolf-beast fighter, prepare for the first battle against the angels that will bring the 「apocalypse」 to the world.

However, during the middle of the first battle with the angel, the magic sword user Elsha, thinking the Demon Queen was “the one who controls the evil demons,” intervened! Although they managed to subdue Elsha and defeat the angel, the situation was completely thrown into chaos.

With their victory in the first battle, the Demon Queen gave Victor orders for the next battle.

“Sophie, Ulrika, Elsha—teach these three powerful girls how to properly use their strength through ‘discipline,’ and defeat all the angels that come our way!”

These girls were problem children who caused all sorts of “failures” due to their overwhelming power. Can Victor properly “discipline” them and protect the world from the angels?
