Fern II appears in the anime *Fighting Fairy Girl Rescue Me Mave-chan*, distinguished by vibrant green hair and striking lilac eyes. She consistently operates alongside Fern 1, forming a protective duo that confronts threats to safeguard vulnerable girls. This proactive approach starkly contrasts with most other characters, who frequently prove ineffective or problematic—Sylphide stands as the sole exception, though concerns linger that Sylphide may absorb negative traits from Mave-chan and Super Sylph through extended exposure.

Fern II maintains a cool, calm, and pragmatic demeanor, serving as a counterbalance to Fern 1’s more volatile temperament. Her composed nature subtly conveys an air of intelligence. Both Ferns share a mutual dislike for the nickname "Two-chan," coined by Super Sylph, though Fern II voices her displeasure with notably less intensity than Fern 1.
