Fourier Lugunica

Fourier Lugnica (フーリエ・ルグニカ) was the Fourth Prince of Lugnica and Crusch Karsten's and Ferris' childhood friend.

Appearance
Fourier has medium length gold hair and red eyes. He wears dress clothes along with a white coat that has fur along the collar. He has a yaeba that becomes prominent when he laughs.

Personality
Fourier was an energetic and magnanimous young man who appeared more self-assured and assertive than he actually was. That said he had a gentle caring heart and a very strong sense of responsibility that earned him the faith and trust of Crusch and Ferris. Moreover, he had the potential to be the current generation's "Lion King" due to his unusually sharp intuition that sometimes manifested which made him seem wise beyond his years. This trait of his only grew stronger as he matured over the years.

Fourier had feelings for Crusch Karsten ever since he saw her at the castle, but because he was a coward, he wasn't able to confess his feelings to her, though he was finally able to do so on his deathbed.
