“The only woman of the Seven Lucky Gods, who is a patron of entertainment, wisdom, and wealth. To bring her blessings to modern entertainment, she's been learning about our world's 'electric guitars' and 'hard rock'."
Benzaiten is based on the goddess of the same name belonging to the shichifukujin (七福神, "seven lucky gods"), ancient deities of good luck originating from Hinduism, Taoism, Buddhism and Shintoism, whose image shifted as they moved from one culture to the other until the coalesced into a group of seven patron gods (the number 7 is a bearer of good luck in Japanese culture).
Benzaiten is traditionally the only woman of the group and is originally derived from the Hindu goddess Sarasvati. In her most modern incarnation, she is portrayed with an elaborate hairstyle and holding a biwa, with a white snake as her animal companion. She is incredibly beautiful, talented and a skilled musician and she is the patron goddess of artists, writers, dancers and geisha.
