Birth of Love
Seira had appeared in a few of Lucia's dreams before, though one of the dreams had predicted a latter even that connected to Mikeru. In episode 3, Lucia was taken to the Dream Corridor to witness Seira's birth, Lucia's objective to teaching Seira how to love someone. Unfortunately, Mikeru came and absorbed Seira within his body, leaving behind Seira's orange pearl.
After Mikeru and the snake spirit had vanished, Sara appeared and gave Lucia Seira's pearl in a little box. Her mission now was to gather all of Seira's heart pieces. Each time Lucia finds a piece of Seira's heart, Seira learns about love and friendship..
Seira has a personality similar to Lucia, considering that Seira's heart was always with Lucia. She always seems to be happy and supports Lucia everytime one of her heart fragments are attained. She loves to sing, considering how she was singing in episode 52, despite the tense atmosphere. She loves ice cream down to the core.
