Together (共に) is the one-hundred and seventieth chapter of The Promised Neverland manga.

Synopsis
It is revealed that Isabella plotted her betrayal to Peter together with the other Mamas and Sister even before Emma and the others infiltrated the farm. At present time, Isabella and her group team up with Emma's group to defeat Peter. However, at the last moment, Peter is able to flee, refusing to lose.

Plot
November 13, 2047, just before Emma's group infiltrated Grace Field House, Isabella gathers all of the Mamas. She informs them that she will betray the farm. The Mamas are shocked at hearing this. Even so, she asks them who among the women want to join her and help the escapees. She has been waiting a long time to reach this moment.

Isabella points out that it is wrong to go against the farm. That they must continue to cling on to the rulers to survive. That was Grandmother Sarah's teaching, and that is why all the Mamas aimed to become Grandmother. But she also questions Grandmother Sarah's whereabouts. For all of Sarah's, she was shipped out for one mistake.

In a flashback, it is shown how the Mamas are put against each other to reach the position of Grandmother, treated like livestock, and forced to give up their babies.

Isabella is angry about how Peter Ratri used her and the Mamas' freedom as bait and flaunting fear. It wasn't nauseating, and she had enough. And now was the time to help her children and get her freedom.

The children are surprised that Isabella and the rest of the Mamas are on their side and question their motives. Isabella is quick to point out that she betrayed Peter because the Mamas and children share the same interests.

Peter finally snaps and grabs a gun, and makes his escape. He cannot accept that he has lost.
