Majo to Tsurugi to Sen no Tsuki | 魔女と剣と千の月

This game takes place after the events of PENDULUM. Peace seemed to have been returned to the world with the decrease in the remaining number of circulars. However, one day the pure white circulars suddenly turned into pitch-black demons who have a increased penchant for destruction. These ‘evilised’ spread all over the world in an instant. The Magus Order continued to fight on the front line, but they were being overwhelmed by the power of the evilised.

In the midst of battle, Ren was turned into a circular due to the great magic power and was going to ‘evolve’ into an evilised until Sayaka was able to seal him in suspended animation. However, they would eventually have to fight against this immense power in the future. As a last resort, Sayaka decided to create the homunculus Rei using a part of Ren’s soul and hidden magic powers to fight against the evilised.
