Chapter 23

Destroy!! (ブチせ！！) is the twenty-third chapter of The Promised Neverland manga.

Synopsis
Isabella gives Krone a letter detailing her promotion to Mama of the fourth premium plantation. However, the letter turned out to be a trick for Isabella to get rid of Krone and the latter got killed instead. Meanwhile, Emma, Norman, Gilda, Don and Ray plan to initiate their escape in six days.

Plot
As the children prepare meals, Isabella goes to Krone's room and passes her a letter, stating it was from Headquarters. Isabella explains that Krone has been promoted to become the Mama of the fourth premium farm and wishes her farewell. Krone thought the offer was too good to be true and grew suspicious towards Isabella's intentions, thinking that the offer might just be a trick to strip her from her role as Grace Field House's Sister. Isabella noticed how Krone is hesitant and purposely questioned whether she is dissatisfied with the offer, whilst secretly knowing how Krone is well aware of her trick. Helpless to oppose and the fact that she could not refuse the headquarter's offer if it really was genuine, Krone decided to take the offer and went to pack her belongings.

Some time later, Phil and Maya joyfully run to Krone's room to inform her to come down for lunch. Isabella halts the two from entering the empty room and lies to them that Krone was "busy with work". Meanwhile, Krone walks briskly towards the gates. At the gates stands Grandmother, her face muddled by the inky darkness of the gates as she gives a smile towards a cautious-looking Krone. Krone passes a letter she has written to Grandmother. The latter read its contents and asks whether the orphans in Grace Field are attempting to escape. Krone replies how she lacks evidence to prove her case and struggles to convince Grandmother to believe her. Grandmother replies that she is not concerned with how the orphans are planning to escape because she believes Isabella would be smart and capable enough to prevent them from doing so. She ends the conversation by explaining how Krone is nowhere as capable as Isabella. Sister Krone finally admits she has lost and says she's been a loser since the very beginning. As she continues, a Demon's hand appears behind her, grabs her, and prepares to stab her with a Vida. Krone's entire life starts to flash before her eyes, as visions appear of her choosing to become a caretaker, her working through the vigorous training of becoming one, her stealing a pen from William Minerva, and her, just recently, placing that pen inside a drawer so that the orphans can later find it and use it to escape.

In her final moments, she encourages the children to escape successfully and survive. The sharp end of the Vida pierces through Krone's heart and she looks up to the sky as she meets her death.

The next scene revolves around Emma, Norman, Don and Gilda. Ray is shown with Isabella. Emma's team is discussing about their escape plan, as they will initiate it in six days.

Research Elements
In this chapter we have the following Research Elements:
 * 23.1 - Those who run the plantations not only use Vidas to kill orphans, but also anybody, or at least under the Grandmother's commands. This could be shown when Grandmother ordered a demon to kill Krone with a Vida.
 * 23.2 - Is was revealed that the Grandmother was once a Mama/caretaker working in one of the plantations. This could be seen when she, dressed in Mamas' uniform, was with a young Isabella in her flashback.
 * 23.3 - Isabella's Mama who cared for her when she was younger is actually the Grandmother herself.
 * 23.4 - Isabella had also attempted to escape the orphanage she was in by climbing over the walls like what Norman did later on in Chapter 29. This also foreshadowed how it was difficult for Norman and his friends to escape later on in the said chapter.
 * 23.5 - The scene where a young Isabella climbed over the orphanage's walls in the Grandmother's flashback could later be later seen in Chapter 37 again in Isabella's flashback.
 * 23.6 - Mamas that are qualified to run one of the premium farms are those who are intelligent and physically strong enough to excel in the plantations' training and tests specified for female orphans. Therefore, Isabella, being the youngest Mama to ever run one of the premium farms, has proven herself to be intelligent enough to outsmart Krone and get rid of her.
 * 23.7 - In Krone's flashback, the training for female orphans who were chosen to become caretakers for the plantations include trials like cross-stitching, Judo, and academics (specifically Biology, as shown on a textbook of Krone's).
