Leficios

Leficios (レフィシオス), or Lefi, is a main character in Maou ni Natta node... She is Yuki's first official wife and the Supreme Dragon.

Appearance
Lefi was a large majestic dragon with silver scales. To acclimate herself to Yuki's dungeon and consume less food, she took an unaltered humanoid form. After doing the deed with Yuki, she noticed she had acquired the Humanoid Dragon title. Shortly after, Lefi found something within herself preventing her from returning to her original form.

When Lefi assumes a humanoid form, she appears to be a 13 to 14-year old human girl with a flawless, slender body. Like her dragon form, her hair and eyes both have a beautiful platinum silver color to them. Even as a human, she keeps her dragon horns and silver tail. While she can hide them, she argues not having them would feel akin to a human who lost an arm or leg.

Personality
Leficios of old is described as a cold and solitary individual by the Spirit Lord. Her overwhelming power caused her to treat everyone equally coldly. Though feared by many, the Spirit King still knew she was kind and didn't cause trouble for no reason. This is proven by how she made an agreement with the human kingdom that tried to kill her and how she didn't immediately kill Yuki after he trespassed into her territory.

Her natural slothfulness is only surpassed by her undeniable sweet tooth. A trait that existed even before meeting Yuki since she spent most of her time sleeping and only made the Wicked Forest her nest because she likes the honey that can be found there.If left to her own devices, she would eat a week's worth of food for two people in a single sitting, while sporting her humanoid body.Unless she's being actively entertained, she prefers to just loaf around.

After meeting Yuki, Lefi's barriers slowly melted away and she shows her emotions of happiness and joy. She has a strong competitive spirit from her stubbornness and can even throw a tantrum when she loses at games.She allows those close to her, like Yuki, to call her Lefy.

She may be a thousands-year-old dragon, but she behaves like a spoiled middle-schooler.It might be due to her innate nature or her undeniable power, but Lefi has a very strong protective instinct for her kin. Being the dungeon residence. As the strongest member of the dungeon, she acts as its ultimate guardian who will annihilate anything that comes to harm it. After Illuna was kidnapped, Lefi immediately mobilized her dragon underlings to help Yuki save her.

History
In the past, before meeting Yuki, Lefi was a member of the dragon tribe and managed to climb the ranks of her kind until she became the Supreme Dragon. Many members of the Dragon Tribe wanted her to become the Dragon Lord but Lefi didn't want the title and so left the village. In doing so, she was met with resistance of the other Dragons who she put out of commission.

At an unknown point in ancient history, Lefi along with the Spirit Lord Yggdrasil and possibly other individuals of great strength fought against the Hadean Helldrake.

When she arrived at the wicked forest, Lefi discovered a beehive with extremely delicious honey and decided to make the wicked forest her nest for a while. In response, the native dragon's all gathered and attempted to drive out Lefi who they perceived as an overpowered invader. Lefi proceeded to beat them all into submission so badly that the fear of her have been scarred deeply into the dragon's souls.

Centuries before Yuki's birth, several human armies attempted to subjugate Lefi for the fame and fortune of defeating the Supreme Dragon. This army was composed of thousands of humanities armies as well as orichalcum Adventurer's who are regarded as Humanities strongest. The army was subsequently annihilated one-sidedly by Lefi. After which, Lefi began destroying the human civilizations, a task that to her, was like pest control. Alicia's king at the time appealed to Lefi by forging a non-aggression pact that promised that humans will no longer attempt any malicious schemes against her or the Wicked Forest.
