Mariabell Rosso

"Indeed. Next time, we will be able to do it next time. I shall gamble on my name, Mariabell the "Greed!"" Mariabell Rosso (マリアベル・ロッゾ) is the granddaughter of Granbell Rosso and a Reincarnated Otherworlder.

Appearance
She looks like a petite young girl at the age of 10 with smooth blond hair and pink eyes akin to her pink lips. She looks similar to her late Grandmother Maria.

Personality
She has a very greedy personality and is very rational in her decision making. She is notorious for manipulating many people's "desires" for her own ends. She is very confident in her abilities.

Due to her avaricious personality, inherited memories and knowledge from her previous world on advanced economics and her own circumstances of not really facing a genuine threat in her second life. Mariabelle is shown to have become completely overconfident and arrogant in her approach to the other natives of the world, as seen where she possessed complete and utter faith and belief that her unique skill, Greed cold allow her to completely dominate and defeat anyone and resulted in her making several strategical errors in her plan to confront Rimuru Tempest due to believing that her overall power could easily defeat a True Awakened Demon Lord, due to believing the overall power level of a demon lord is only equal to that of a self proclaimed one.

This also resulted her in severely underestimating her "pawns" such as Yuuki Kagurazaka, due to believing that her "Greed" was powerful enough to dominate him that later resulted in her defeat and her skill being taken from her.

Background
Mariabell was an Otherworlder who died and got reincarnated here as a new person carrying her memory of the previous world.

She is the princess of Siltorozzo, a small constituent nation of the western alliance north of Farmas kingdom. The Royal family of Siltorozzo is called Russo family and it built its strong roots in the Western Nations and owns all authority. The members of their family had a hand in every powerful nation, including the likes of Farmus and Ingracia. It was also their family's contributions that led to the creation of the Western States Council. To the outside world, it appears that the Council elects its members from every nation. But they are, in fact, mostly members of the Rosso family. And their increased presence grants them enough prestige to surpass powerful nations. Yuuki Kagurazaka's funds to found the Freedom Association also came from the Rosso. If anything, these elders could be considered the rulers of the Western Nations and their leader is Granbell. Dominating the human world through the economy, that is the ultimate goal of the Russo family.

Unique Skill

 * Greed - This Unique skill granted Mariabell various abilities and powers that gave her an overall power level equivalent of a Self-Proclaimed Demon Lord. As seen where she could "dominate" and mind control someone else by controlling their "greed" with her own, burn parts of her "pawn's" soul in order to increase their physical abilities and powers and burn away parts of her own soul in order to increase her own power.
