Mary

Mary is a character from the RPG Maker game Ib, and the host of the King for a Crazy Day Tournament.

Biography
This version of Mary is from a timeline where Ib  never happened. Her painting was brought to life by Hades, who forced her to gather wayward souls to participate in his tournament.

As the host, it was Mary's job to bring contestants to the Loser's Chambers and to trap them in a painting when they lost once and twice. This gave her negative reception among the competitors.

She later killed Light Yagami when he failed to obey her and Betty when she attempted to kill her after she attacked Hyperchan. She also took a liking to The Ice Queens and spilled the beans to them, but this was later used against her when Hades punished and fatally wounded her.

Byleth later came to visit her, as they were apparently old friends. Byleth gave her the MF Like Button and told her to use it when Hades became too power-hungry.

At the Grand Finals Mary sacrificed her life to kill Hades.
