Meiru Melusine

Meiru Melusine (メイル・メルジーネ) is 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 is a Dagon-Vampire Mix-blood, and an Atavist, with the ability to use one of the Ancient Magics from the "Age of God". She is also the creator and caretaker of Melusine Labyrinth.

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

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

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

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

Meiru is greedy and will look for any opportunity to get rich, including stealing.

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

Due to being in possession of Ancient Magic, Meiru is somewhat arrogant in her abilities and believes 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 loves being by the ocean and enjoys swimming.

Quotes

 * (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.”
