On the next day, Mizuki joined the girls and Sorte's tribe to confronted he Child Room. While observing from afar, Mizuki learn from Gisele that something was wrong about the deal, while heard her suspensions that the "Myrta" they saw wasn't exactly the real one. The suspicion was confirmed as "Myrta" began to attack Sorte, only to be saved by Toshu. The girls then witnessed the heated battle between Toshu and Sorte's Dogma against Mammon to keep Mammon from Sorte. Much to the girls's horror however, it was Mammon's decisive victory as he shape-shifted as Sorte and used Toshu's confusion to decapitate him with a clean cut. With Sorte traumatized over the loss and held hostage by Mammon, who is returned in his normal form, the girls left no choice but to surrender.

Mizuki and Gisele, without Kotonoha with them, were held hostage by the Child Room and witnessed the brutal ritual ceremony by Buster, with Sorte's father's bone and Sorte blood to create the bloody Teyotoyo Tattoo. During the ritual, Mizuki and Gisele then witness the Elder Chief came in and try to stop the ritual by made his plea to Buster; only to be horrified that Buster shot the Chief to it's his torso. As the ritual is succeeded and Buster demanded more blood for further to control the Teyotoyo Giant, Mizuki tried to stop Buster but slapped onto the ground. Had enough of Buster cruelty, Mizuki and Gisele stood up and defended the Elder Chief while insults Buster by calling him "chicken-head", for bullying the weak and young.

Unfortunately, Buster is proved overwhelming to both girls and Mizuki was beaten badly by him before she rescued by the injured Chief, who survived the gun shot and attempted to rescue her even he is too beaten in the progress. Mizuki urged Buster to stop his beating while listened to the Chief's words: She is his first precious friend ever in his life and he is willing to protect them even he had to die for it. Unwilling to see more cruelty, Mizuki made her failed attempt to stop Buster, only to pushed back to the ground and prompted her to think about her weak power even though she is an A Ranked Mercenary; while helplessly seeing Buster trying to shoot the Chief in point-blank range.

Miraculously, Mizuki and group is narrowly rescued by Morito and his group (Myrta, Mammon and Iria), who escaped from the unknown being into the Teyotoyo Temple. She urged Morito to escape but Morito showed no fear instead, further inspired Mizuki who claimed Morito as great and awesome. Although rescued and Buster defeated, the group face a new problem: the Teyotoyo Giant Toshu now reached to the temple, while grabbed an unconscious Sorte in his giant hand and absorb her into his body. To make matters worse, the giant now viewed everyone as Sorte's threat and decided to decimate them to make them pay for Sorte's torture, including Morito and his group.(Though Buster was actually responsible to Sorte's torture). Facing with the Giant's wrath, Mizuki and the group made their escape from the giant before saved by a tank shot from Daigo, the Hamelins and the survived pilot as it's rescue. She is then witnessed the Giant was firing another deadly energy beam to the tank. Fortunately, the tank is saved by an awaken Nanoha, who was deflect the beam.
