After being told off by Seigen, Benio and Rokuro stayed in a bad mood until Mayura comes over to cheer the two of them up. She cooks dinner for the Twin Star Exorcists and walks home with Rokuro in tow. Along the way, Mayura was corrupted and she turned into a Impurity. Rokuro refuses to purify her as Benio and Seigen joins him. Seigen battles Impurityk Mayura but finds it nearly impossible to purify her. Rokuro, still defiant, asks Seigen if there is another way of saving Mayura. Seigen explains about a technique known as Furu no Koto that he believes only the Twin Star Exorcists can do. The duo casts the technique and Mayura is purified. Yuuto then appears and congratulates Rokuro.
