Greenhouse

Erina Tokiwa is a renowned artist who uses flowers in her pieces but kills one of her admirers, believing that it would bring her art to new levels, when a Horror approaches her. Meanwhile at the Saezima estate, Mayuri keeps awake at night and when Gonza suggests her to take a rest, she claims that she has been sleeping for a long time. Now possessed by the Horror Succubus, Erina kills a woman to make another piece of art before she meets Mayuri and becomes interested in her, drawing the girl to her atelier at a greenhouse. The Watchdog realizes this and informs Raiga, urging him to strike the Horror down, but claiming that protecting Mayuri is not a priority. Zaruba guides Raiga to the greenhouse where he confronts Erina who has realized that Mayuri is not human and treats her as an object, much to Raiga's anger. After Raiga cuts Succubus down, Mayuri reveals that the seed of Eyrith was not inside that Horror either, and becomes curious as to why Raiga treats her as a human, despite knowing that she is not.
