Info: Algos appears in the Prologue chapter of the regular manga. Venus calls upon him because she is upset and jealous over the human girl name Psyche. In Greek mythology, Algos is the plural form of Algea which were spirits of pain and suffering. This character only appears by Venus’ side for a few pages.
