20

Rin and Yukio find that their friends from their monastery were attacked by a masked individual who covered their entire bodies with seemingly indestructible cobwebs. While pursuing the culprit, whose objective is to attack anyone related to the son of Satan to make him suffer, Yukio stumbles into Neuhaus, who flees without further explanation. Despite Kurikara being sealed by the cobwebs, Rin insists on going after the masked man, but Yukio tranquilizes him. Yukio heads to the sewers to find any trace of the masked man, but he finds Neuhaus there, who flees from him again. After Rin wakes up, Shura motivates him to light the candles correctly. Yukio receives word from Tsubaki that Ryuji, Konekomaru and Renzo are being held hostage by the masked man in the male dormitory of the academy. Before being able to intervene, Mephisto is taken away by Arthur, who suspect him of directing unauthorized biological research. Yukio rushes in to save Ryuji, Konekomaru and Renzo, only to be captivated himself. As Shura is also trapped by the cobwebs, Rin manages to control his flames properly, defeating the masked man and safely releasing his friends. The masked man flees, thanks to Neuhaus, but Shura realizes that a woman was behind the mask, who is revealed to be Neuhaus's wife. Rin burns off the cobwebs from his friends from the monastery, while Yukio is summoned to meet with a mysterious man. (Source: Wikipedia)
