Power

I won't eat meat with vegetables!

She threw a plate of vegetables at the wall and ate the meat itself.

When they were trapped in a hotel due to the ability of the Eternity Devil she spent most of the time there "planning" to win a Nobel Prize and become Japan's Prime Minister so she could raise up their taxes up to 100%.

She has no problem gossiping and talking about her friends behind their backs; sharing the secret of Aki's shortened lifespan with the Angel Devil.

Power sees no difference between pork, beef and human meat; being willing to eat all of them, even if the meat is disgusting zombie flesh.

She hates vegetables, throwing them away when she finds them in her meal.

Power is an insatiable glutton, eating all of the stored food that the team needed in order to survive the Eternity Devil's trap and hoarding food for herself at the Division 4's newbie welcoming party.

When asked by Aki about what reward she could want as part of their mission, Power stated that she desired to suck a human's blood until they die. When promised Denji's blood, Power became ecstatic at the prospect.

After returning from Hell and witnessing the power of the Darkness Devil, Power develops severe PTSD, being completely afraid of being alone and feeling that she will be swallowed by the Darkness Devil. As a result, she needs Aki and Denji to help take care of her, helping her to eat, bathe, and sleep, revealing a more vulnerable side.

Though she is extremely selfish, Power was able to experience compassion for the first time towards her pet, after only caring about the smell and taste of blood and the feeling of death when she was killing something. This compassion prompted her to act for the sake of another being when her pet Meowy was kidnapped.

Power also begins to care for a select few close friends, such as Denji, as evidenced by getting him a birthday cake, and later putting herself in direct danger in order to protect him. She also appears to care about Aki and is saddened and afraid when he becomes the Gun Fiend.
