Alice in Murderland Vol 7

From the Yen Press edition

It's sister vs. sister in a fight to the death! Stella makes a pact with Alice to save both their lives, but it seems Ibara's just getting started. The eldest sister is out for blood, and she won't stop until there's only one girl left standing. But if Stella survives this fight-what then? What havoc will Alice wreak if she's got control of their body for a whole month...?
