Billie Za Gozzila

The MangaPlus translation romanizes her full name as "Billy Za Gojila." Akira Amano, however, spells her nickname as "Billiegozzi" in one of the unlockable bonus sketches. As an extension, Billie's full name might be meant to be spelled as "Billie Za Gozzila." The wiki will use "Billie Za Gozzila" to be uniform with her nickname until another spelling is confirmed.

## First appearance

### **Manga debut**

Volume 11, Chapter 97

**Billie Za Gozzila** (ビリー・ザ・ゴジラ, *Birī Za Gojira*, lit. "Billie the Godzilla"), frequently shortened to **Billiegozzi** (ビリゴジ, *Birigoji*), is a student at BLUE.

## Physical description

## Personality and traits

Billie is an animal friend and owns several pets. Because she brings them everywhere, Billie is often talked about in staff meetings.

## Biography

### Ron Kamonohashi's Homecoming Case

The day Ron Kamonohashi and Totomaru Isshiki arrive at BLUE, Billie comes to class with her pets, much to Udy Dietner's dismay. Minigozzi even jumps on Toto during his lecture.

Later, Billie watches Toto solve the mystery of Alissa Beaumont's "murder" as well as save Alissa from falling off the window ledge.

The next day, Billie goes to BLUE and runs into Toto, Ron, Alissa, Udy, Marsh Leipley, and Night Bran Jr. on the way. Hutter Horn is already there and waves at them in panic when they arrive. He came to BLUE to talk to Aimee Emmerich about his academic advancement plan, but when he entered her office, he found her collapsed at her table. Immediately, everyone rushes to Aimee's office and discovers that Aimee was shot and a strange video is playing on her laptop.

### Cryptid Serial Murders Case

Ron orders the students to stay back while he examines Aimee's body; with a heavy heart, he confirms her death. Aimee died two or three hours ago, and the bullet passed through her body and is now lodged in her chair. The murder weapon lies on the ground, empty of bullets.

When Toto and Ron are done inspecting the crime scene, Night tells them that Aimee asked him to see her an hour ago. Alissa was also called by Aimee to help move Billie's pets, and Alissa asked Udy, Marsh, and Billie to assist her. Everyone, thus, deduces that whoever killed Aimee must have called them to BLUE, possibly so that they find her body. This means that Aimee's murder is a declaration of war to Billie, the other students, Ron and Toto.

Then, the academy's guard comes into the office, intending to ask Aimee whether the emergency isolation system is running. When it is activated, the system blocks internet and phone signals as well as pulls the drawbridge. Toto and Ron rush outside to check the bridge, but it was already drawn and because only Aimee knew the isolation system's deactivation code, they are now trapped in the school.

Later, everyone gathers in a lecture hall to discuss why they might have been isolated at BLUE and how to proceed. While Ron and Toto check Aimee's laptop, Billie and most other students separate and wander alone through the school. Billie is then attacked and screams but is not discovered until the night when Minigozzi guides Ron, Toto, Hutter, and Night to the locker room. Billie was tied up and placed in the water-filled locker, and Hutter quickly picks the lock and manages to rescue her on time. A cover page from the *Guardian of the Citadel* has been left with Billie too. To their horror, it is "Chapter 3: The Terror within the Water Merman," meaning there was another murder while they were searching.

Everyone hurries to the roof where they find Chelsea Gadd's corpse. The cover page of "Chapter 2: The Giant's Awakening Cyclops" lies next to her, and she curiously seems to have died by falling. Billie tears up at Chelsea's sight, and Alissa comforts her. When she notices that Billie is cold because of her drenched clothes, she and Marsh escort Billie to their classroom so that she can change into her gym clothes. The others split into two groups to investigate in the meantime.

An hour later, everyone reassembles in the locker room and shares their findings: Someone broke into the guard station and destroyed the sensors that detect entry and exit, and Ron and Toto found a body bag with blood inside and a pole with scratch marks on the roof. Afterward, Toto and Ron examine the third crime scene, and Billie tells them that she went looking for her pet rabbit and cat earlier. Right after she spotted Udy's corpse in the courtyard from a window, she was attacked from behind and knocked unconscious; she woke up again in the locker.

Ron lies down in the locker and finds strands of long, white hair. Night then whisks Toto and Ron away to the rooftop; Toto tells the rest to wait in the dining hall. Wanting to consult with Totomaru, Alissa follows them to the roof, and Billie accompanies her. In reality, Billie uses this opportunity to catch Alissa.

Billie ties her up and prepares to collect her blood and kill her, as her death is meant for "Chapter 4: The Immortal Monster Vampire." When Night eventually comes to rescue Alissa, Billie manages to overwhelm and catch him. By the time, Ron, Toto, Marsh, and Hutter arrive in the secret tunnels, Billie has drawn a significant amount of blood from Alissa and Night, but has not killed them yet.

Upon being confronted, Billie reveals that she neither anticipated Toto and Ron's arrival nor Chelsea's presence. Still, she managed to incorporate them into her plan; e.g. when Chelsea spotted her re-entering the school via the the lowered bridge after she picked up a new pet, a pomeranian, Billie was swiftly able to devise a plan to kill her. Billie also "ad-libbed" a show for Toto, Ron, Marsh, and Hutter: To test Toto's reflexes, she has set up crossbows that will shoot arrows at the unconscious Night and Alissa in a moment. To Billie's surprise, Marsh helps Toto though; together, they can save both Alissa and Night.

Afterward, Billie flees. However, Hutter can track her down, and Billie surrenders when he and Totomaru arrest her. Not long afterward, the police arrive; as they escort her to the paddy wagon, Billie sings "Humpty Dumpty had a great fall... and then his hair was silky and smooth" which piques the interest of Winter Moriarty who arrived earlier with Spitz Feier.

On the way to the police station, the masked swordsperson of the M. Family cuts open the vehicle's roof. They kill the policeman and break Billie's cuffs. She then takes off her disguise and is carried away by the swordsperson.
