Re:Zero – Starting Life in Another World features the character Felix Argyle, a skilled catboy healer within the series’ expansive cast. Felix, officially known as Ferris, serves as a supporting character, first appearing in the light novel series written by Tappei Nagatsuki. His anthropomorphic cat-like features, including cat ears and a playful demeanor, make him distinctive in the fantasy world of Re:Zero. Felix plays a vital role as the Crusch Camp’s court healer, showcasing exceptional magical abilities and medical expertise.

Known for his unwavering loyalty to Crusch Camp and his peculiar speech pattern, where he frequently ends sentences with “nya” (a Japanese onomatopoeia for a cat’s meow), Felix quickly became a fan-favorite. In the anime adaptation, Felix’s character design and vibrant personality further contribute to the series’ diverse and memorable ensemble. Beyond his humorous antics, Felix’s moments of seriousness and dedication to healing duties add depth to his character, making him a nuanced and well-rounded presence in the intricate narrative of Re:Zero.
