Meiru Melusine

Meiru Melusine (メイル・メルジーネ) was a character who appears both in the main "Arifureta: From Commonplace to World's Strongest" series as a minor character, and in the spin-off "Arifureta Zero" series as one of the main protagonists.

She was a Dagon-Vampire Mix-blood, and an Atavist, with the ability to use one of the Ancient Magics from the "Age of God". She was also the creator and caretaker of Melusine Labyrinth.

Appearance
Meiru was a beautiful woman in her early 20s with wavy emerald-green hair and narrow jade-red eyes. She had a slender body along with very voluptuous breasts. Due to her dagon heritage, she had fin-shaped ears.

Meiru usually wore a blue and white bikini, a mini skirt in the same colors, and a large belt. She also wore a white jacket that is adorned on her like a cape, and a black and white tricorne cap.

On her belt, she carried a beautiful saber with an elaborate cross-guard design.

Personality
On the surface, Meiru was a kind a charming woman who was always smiling. In realty, however, she was mischievous and sadistic. She enjoyed teasing others and would torment her enemies to the point that it would look like she was torturing them. Even so, Meiru cared greatly for her allies and would risk her life for them. She was charismatic enough that she managed to recruit hundreds of pirates that would gladly lay down their lives for her. She was also a good judge of character and could easily discern those that she could trust.

Although Meiru would frequently tease those around her, she was unable to properly respond to others when they teased her.

Meiru was greedy and would look for any opportunity to get rich, including stealing.

Despite her position as a pirate captain, Meiru did not like to think about anything too difficult and would immediately lose focus whenever a topic came up that she was uninterested in. She was also very sloppy and incapable of doing the most basic household chores, such as cooking and cleaning.

Due to being in possession of Ancient Magic, Meiru was somewhat arrogant in her abilities and initially believed herself to be practically invincible. This would later change, however, after her failed attempt to save Oscar Orcus's siblings with her magic, and later Miledi.

As being part dagon, Meiru loved being by the ocean and enjoyed swimming.

Physical Abilities

Magical Abilities

 * Immense Mana - Unlike normal beastmen, Meiru possessed mana and the ability to manipulate it due to her half-vampire heritage and atavist nature, respectively.

Quotes

 * (Her last words to Miledi): "Remember, you’re not alone. Even if I die before you, I’ll be thinking about you for all eternity."
 * (Meiru's recorded message): "Please, don’t cling to the gods. Don’t rely on them. Don’t grow accustomed to what’s given to you. Struggle on, and grasp what you desire with your own two hands. Decide your own path in life, and walk down it with your own two feet. Remember, no matter how bleak things look, you’ll be able to find the answers inside of you. Only you have those answers. Don’t be deceived by the gods’ honeyed words. Only when you live by your own free will can you find true happiness. I pray the path you walk will be forever showered in fortune.”
