Seo Akira (瀬尾 晶, Seo Akira?) is an underclassman and friend of Tohno Akiha's at Asagami Private Girls Academy. Her eyes give her minor precognitive powers (although usually not entirely clearly), and she previously appeared on the Tsukihime PLUS-DISC. She met Tohno Shiki in the events of "Alliance of Illusionary Eyes", and they have remained in contact, to Akiha's chagrin.
