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


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.


Although Fourier wasn't much of an administrator, he was shown to be enthusiastic and virtuous. Despite his work not being that important as he was on the lower part of the line of succession, he still made sure to try his best at it. He was shown to be absolutely loyal to his friends and would do anything for them.

It was also shown that Fourier apparently had the qualities necessary to be a Lion King, however because his childhood teacher failed to notice it, no one knew about it.

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.
