Strike the Blood Episode 20 English Subbed Episode Title:Return of the Alchemist I.Episode Description:Alchemist Kou Amatsuka visits Kensei Kanase, in pursuit of an artefact in his possession known as Wiseman's Blood. The middle school students shop at the mall in advance of their off-island training camp. Accompanying them, Kojo is attacked by Amatsuka who seeks to use Kanon as a sacrifice. Amatsuka comments on an incident at Nina Adelard's monastery, which is apparently also the ruined church and cat haven. Yukina joins the fray and the alchemist departs. Astarte explains alchemists to Kojo and mentions the legendary Nina Adelard, who would be centuries old were she still alive. Kojo and Asagi, approaching the ruined church, are intercepted by Natsuki but while there, Asagi loses a precious ear stud in the grass. Yukina leads Kojo to a seedy part of town where the Lion Kings' island branch is secreted away. She hands in her halberd while her master, in the form of a cat familiar, meets the Fourth Progenitor. At the ruined church, using Wiseman's Blood, Amatsuka conducts a ritual designed to force out his former master Nina. It is successful but she is able to flee. Asagi, returning to search for her ear stud, is struck and perhaps slain.
