About Seira in pitch pitch mermaid

Seira is the future Mermaid Princess of the Indian Ocean, the successor who will follow in Sara's place. However, there's just one tiny problem... Seira hasn't been born yet. Before Seira's birth Michel attack her. Luchia has to fight for the fragments of Seira's heart. Seira is still alive because of her orange pearl which Luchia keeps in a box. Slowly Seira learns what happiness feels, sadness, friendship, and etc. In the very last battle Fuku-chan follows Seira and the mermaid princesses down to Earth, and, overwhelming Michel's will, uses the angelic being as a puppet who attempts to hunt down and destroy the princesses and their allies. Even when confronted with an evil, soul-less Michel, however, Seira's heart aches for him. "Michel really truly is a nice person, just like Michal!" Seira tells Luchia. Seira wants nothing more than to save Michel from Fuku; and with Luchia's help, ultimately, the strength of Seira's love for the forlorn angel is enough to do so. It is telling that when his moment of salvation comes, Michel's final words of farewell are to Seira, and to Seira only. "Believe that we will meet again someday..." Seira weeps tears of mixed joy and grief as Michel leaves her. Seira ultimately proves herself a profoundly kind, gentle, yet strong person. Her experiences sharing Luchia's emotions, and then Michel's emotions, have taught Seira many things about the strength of love, and the pain of loneliness. Watching Seira's determination to save Michel during the final battle, Coco even comments, "Sara... The little princess of your kingdom has already become a wonderful friend."
