Maria Naruse is a succubus and Mio's guardian. She is the daughter of Shella, Lucia's sister and one of the main female protagonists.


Maria is a beautiful girl with long silver hair and purple eyes. She is a loli. Upon turning into her succubus form, she wears a very revealing outfit.

In Episode 10, she transformed to be a grown, curvy woman as she was ordered to dominate Basara.


Maria is a rather childish person and she likes teasing people no matter how serious the situation is. Despite this, she can be dead serious as seen when she revealed her real identity to Basara.



Maria was born the illegitimate daughter of the then current Demon King Wilbert and a succubus of great renown Shella. In the same way that Wilbert gave the majority of his power to his first Daughter Mio, Shella also decided to gift the majority of her power to Maria, which as a side effect has reduced Shella to a weakened and younger looking form.

Six month's prior to the series start Maria was sent to rescue Mio whose adoptive family was under attack by the Demon Council Member Zolgear, the two of them narrowly escaped thanks to Maria temporarily unlocking her full power. Since then the two of them were on the run until they were found by Jin Toujou who tricked them into trying to brainwash him into taking them in under the pretex that he was going to marry their mother.

Powers & Abilities

Maria is the groups brawler. Her melee fighting style focuses on using her agility coupled with heavy punches and kicks to defeat her opponents.

  • Super-Human Strength: Despite her small size, Maria is a strong succubus. Her skills can't be compared to Basara considering he easily overpowers her, even after being rusty due to his exile from the Village.
  • Master-Servant Contract: She's able to use her succubus abilities to create master servant pacts, partially distort peoples memories, and make people succumb to lust and carnal desire.
  • Magic Key: Maria has a trump card given to her by her mother Shella. This form increases Maria's physical strength and succubus abilities.
  • Gravity Magic : After losing to Lars in volume 7, Maria decided she needed to get stronger and started to train with Basara. She ultimately discovers that she can emit a crimson aura and manipulate gravity like Mio and Basara. She isn't particularly good with it though and it puts strain on her body because she doesn't entirely understand how it works at first.
  • Reverse Magic Key: After completing the vow with Basara, Maria learns the truth about her birth and unlocks her true power. During the battle with Kouryuu, Maria uses the reverse magic key. instead of turning into an adult succubus, Maria stays her normal size, but gains immense physical power and speed. The cost associated with using this power is that it depletes Maria's life force.
