Seira is the main heroine from Takumi's favorite anime "Blood Tune: The Animation", and also Takumi's favorite character. Occasionally, she shows up in Takumi's delusions, trying to deviate him from reality and push him to be a shut-in. Her delusional appearance is in fact Takumi's own weaknesses given voice.
