*This book was given to me in exchange for an honest review.
In an attempt to repair Juzo, he and Mary end up trapped in the weapons vault with May trying to save her brother as well a Juzo from the twisted horrors contained in the vault trying to destroy them.
Of all the characters, I find myself appreciating Olivia more each time she makes an appearance. She may be designed like a typical fan service character but, she is smart and capable; so you engage with her as a part of the story and not an ornament.
Overall, this volume left me satisfied in terms of dealing with Violet but unsatisfied in general. I feel like some plot points went by too fast. I liked it but not as much as previous ones. 3.5 out of 5.
