Krone

Krone (クローネ, Kurōne) also known as Sister Krone was a helper in The Promised Neverland and helped run the Grace Field House orphanage with Madam Isabella. She would eventually attempt to usurp the position of "Mama", an act which would lead to her death at the hands of Isabella, Grandma and the Demons.

Appearance
She possessed a large and intimidating physique, which coupled with her equally intimidating facial expressions made her seem dominant, though she outwardly often wore a bright, warm smile.

Personality
Krone was an individual who fought for nothing but her own, personal, agenda. She played nice when she had to play nice, scheming and plotting continuously while trusting no one but herself. She fully realized the evil of her own actions, and how the twisted system she was brought up in made her this way, but still carried on nevertheless. Her goal was ultimately just to survive, to be on the "Eat" part of the food chain.

History
She was brought up in an "orphanage" similar to the Grace Field House and performed well enough on the tests to be recommended for Mama-training when she turned 12.

Intelligence
Krone was very intelligent, having obtained perfect scores on the daily tests during her own time in an "orphanage". However, she was still inferior to Isabella and fell short in her attempts to outwit her as she tried to usurp Isabella's position as "Mama" of the orphanage. Nevertheless, she continued her attempts to obtain an advantage so that she can "drag her down" from her position.

Madam Isabella
is her superior and asked for her to help keep watch over the children of the orphanage. At first, Krone admired and respected Isabella, being delighted at the chance to work by her side. Though as Isabella revealed the present problematic situation, Krone immediately saw it as an opportunity to exploit her for her own promotion, which led to her scheming to usurp the position as "Mama".

Grandmother
Krone told Grandmother about the escape plan but Grandma still had her killed.

William Minerva
Not much is known about Krone's relationship towards Minerva. The only link between these two is a mysterious pen that she left in the drawer for the orphans; this has been seen to hold the coordinates of Minerva's whereabouts.
