Lilianna Centostella

Summary
Centostella Kingdom's First Princess. It's unknown if she has any siblings. When Takahisa got depressed after his summoning, due to the sadness of being away from his loved ones until the point of not eating and collapsing, Lilianna was the one who helped him back to his feet. There aren't any details about her time with Takahisa before the evening party.

When Satsuki's invitation to the evening party arrived, she advised her father to allow Takahisa's attendance, thinking that it would be something necessary in order to help him to regain his spirit. When she saw how overjoyed Takahisa became upon meeting Satsuki and Miharu, she was convinced of being right in her decision, but she soon recognized the rivalry that formed between Takahisa and Rio, seeing his closeness with Miharu and how Miharu, despite being with him, didn't stop giving off signs of preferring to be at Rio's side rather than his.

How to mediate between Takahisa and Rio became her number one concern. By meeting Rio and hearing everyone's opinions of him, she understood that he was a good person, but not taking Takahisa's side in this conflict would be against her father's orders of supporting Takahisa. This put her between a rock and a hard place.

She constantly tried to stop Takahisa from acting on his jealously and insecurities but wasn't able to in the end. For her, it really was heartbreaking when Takahisa threatened to stop being a hero if she wouldn't assist him with Miharu's kidnapping. Feigning cooperation, she deceived Takahisa into accepting the role of Centostella's hero from then on, in exchange for lending him her magic ship to execute his stunt. Behind his back, she warned François of his plans to prevent war between their kingdoms. She and Takahisa returned to their kingdom with Aki and Masato in tow.
