Majo to Tsurugi to Sen no Tsuki

In 'Witch and Sword and a Thousand Moons,' a sequel to PENDULUM, peace seemed restored after the circular beings dwindled. But one day, pure white circulars mutated into pitch-black demons with a frenzy for destruction. These 'evilised' spread worldwide instantly. The Magus Order fought valiantly but was overwhelmed. Ren, caught in battle, transformed into a circular and neared evolution into an evilised, forcing Sayaka to seal him in suspended animation. To prepare for the inevitable confrontation, Sayaka created Rei, a homunculus from Ren's soul and hidden magic. From Hau~ Omochikaeri!
