Danka is a supporting character from the anime Skeleton Knight in Another World. He is an elf warrior with a distinct and cautious personality, defined by his loyalty to his people and his initial wariness of the protagonist, Arc.

Physically, Danka is an adult male elf with blonde or yellow hair that reaches his neck and green eyes. His full name is Danka Niel Maple. As an elf, his naming convention includes the family name Maple, indicating a connection to other elves of his tribe, such as his comrade Ariane Glenys Maple.

In terms of background and role, Danka is introduced as a traveling elf warrior. His primary mission is to journey through various lands to locate and rescue fellow elves who have been captured and sold into slavery. This personal quest drives his actions and defines his moral compass. He is first shown in the town of Diento, where he has been gathering intelligence on the local elf slave trade. He acts as a contact for Ariane, who hires the protagonist Arc to assist in a dangerous rescue mission.

Personality-wise, Danka is characterized by his seriousness and caution. He is naturally wary of outsiders, particularly humans, which stems from the reality of elf hunting and slavery in his world. When Ariane introduces Arc, Danka is initially cold and skeptical of the skeletal knight's intentions. His distrust is not born of cruelty but of pragmatism and a deep-seated need to protect his people. In the source material, this skepticism runs deeper, as Danka finds it difficult to trust Arc due to inconsistencies regarding the knight's true nature and appearance. However, he is not unreasonable. Once Arc demonstrates his immense power, such as breaking a sealing curse with ease and using teleportation magic, Danka’s professional respect begins to outweigh his personal suspicion.

Danka’s key relationships center on his comradeship with Ariane. There is a clear sense of mutual trust and shared responsibility between them. Ariane relies on Danka’s reconnaissance, and he, in turn, respects her judgment, even when he questions her decision to bring an outsider like Arc into their plans. He also shows a protective side, particularly towards the young elf children they rescue. After freeing them, Danka takes personal responsibility for their safety, choosing to escort them home himself while leaving the more dangerous task of confronting the lord to Arc and Ariane. He also asks Arc to look after Ariane, demonstrating his concern for her well-being.

Regarding character development, Danka’s arc within the anime’s fourth episode is one of initial distrust giving way to reluctant acceptance. He begins as a skeptic who questions Ariane's choice of ally, but by the end of the mission, he acknowledges Arc's abilities and entrusts him with the critical task of rescuing the remaining captives. His parting words and actions show a newfound, if cautious, faith in Arc’s strength and reliability.

As for notable abilities, Danka is depicted as a capable and experienced warrior. While his specific combat skills are not detailed extensively in the episode, his role as a traveling elf warrior on a dangerous rescue mission implies he is proficient with weapons and survival tactics. His most notable contribution is his intelligence-gathering ability, having successfully pinpointed the location of the enslaved elf children within the city of Diento. Outside of the main storyline, Danka is also known as the protagonist of a spin-off gourmet comic called Danka Meshi, which focuses on his enjoyment of tasting local specialty dishes during his travels.
