Nightmare x sisters Ω ~Shuumatsu no Requiem~

Synopsis

Setsuna, Yuuka, and Rinne, who had been continuing their battle against the Demon Cult, were undergoing rigorous training in preparation for their next battle, aiming to level up even further.

Just then, they heard that the cult leader, who could be called the root of all evil, had begun to move again, so they decided to return after finishing their training. They joined forces with Kuon and Rei, who had fought the revived cult leader over the sacred sword Amagumo no Tsurugi, and finally began their campaign to destroy the cult.

Just as they were about to move forward, the cult leader, who had obtained the Amagumo no Tsurugi, vanished once again, leaving them with the urgent task of locating his whereabouts.

Setsuna, who had to wait until the whereabouts of the cult leader were known, proposed that they all live together in preparation for the decisive battle. There was a family dormitory in the city where the headquarters of the church to which Setsuna and the others belonged was located, so they decided to start living together.

Even as they spend their days in temporary peace, the Setsuna group continues to prepare for the impending decisive battle. Georgi, the elite exorcist who accompanied the Setsuna group on their training, will also lend his strength, and the momentum for the defeat of the cult leader grows stronger...

Despite various accidents along the way, they gradually move closer to the final showdown with the help of Chisei and others they met at the academy.

What awaits them at the end is either the exorcism of the evil demon or an endless cycle of torment.
