Mabel dislikes work but enjoys showing off her military ranking to feel superior. She has a soft spot for Ojisan, so much that her sword seems to “melt” in his presence. Around Sui, she behaves submissively, treating her almost like a master.

Mabel Rayveil, last descendant of the Ice Clan, grew up in a freezing village and kept the legendary Ice Sword, said to be the only weapon against the Fire Dragon. Her emotions affect the ice around her, and she often led a reclusive life, disliking work. When she met Ojisan, he thawed the ice around her sword and gave her a Cosmic Ring, sparking a complex bond that blended admiration, jealousy, and playful rivalry with Sui and Elf.

Mabel went through existential crises, chased Ojisan with her scythe-shaped sword, and caused chaos that led to misunderstandings and bonding moments with Elf and Sui. She gradually opened up, revealing her past misdeeds, like freezing villagers, and showed her affection for Ojisan, even thawing her sword whenever he was near. Their interactions often combined humor, tension, and heartwarming moments.

Later, Mabel aided Ojisan and his allies in key events, including confronting dangerous foes, escaping mercenaries, and assisting in battles. In the season finale, she acted as bait against the divine-powered Fire Dragon while Ojisan, Elf, and Sui launched a combined attack. After the fight, Ojisan revealed his real name, but Mabel and Alicia preferred his aliases, maintaining the playful dynamic between them.
