Seira is the main character in Blood Tune and features heavily in Takumi Nishijou's delusions.
Her appearance is similar to Lala Satalin Deviluke, but with smaller bust size.
She is mostly a support for Takumi and is based on one of his favourite anime girls who he has many statues of. She appears near the beginning of the first episode.
