After introducing rival magic girl Miyu Edelfelt in the last anime visual, a newly published Fate/kaleid liner Prisma Illya pic shows off Illya's predecessor, Rin Tohsaka, along with Miyu's, Luviagelita Edelfelt.
In Fate/kaleid liner Prisma Illya, Rin and Luvia were Class Cards collecting magical girls until their rivalry grew so heated that Ruby and Sapphire Kaleidosticks abandoned them, after which Rin and Luvia took on Illya and Miyu as proxies for their competition.
Luvia previously appeared in the mainline Fate series, most notably in visual novel Fate/hollow ataraxia, as a classmate/rival of Rin at the Mage's Association academy, Clock Tower. Her specialties include use of a pro-wrestling-like martial art.
First announced back in April, the magical girl anime is now slated to premiere in 2013, with Silver Link (Baka to Test, C^3) producing the Shin Oonuma (Baka to Test) directed project.
