Mizuki Segawa

Mizuki Segawa is a major supporting character in the manga and anime series Guyver: The Bioboosted Armor. She is a 17-year old high school student and the romantic foil of series protagonist Sho Fukamachi. Initially oblivious to Sho's affection towards her and his struggles as the Guyver, Mizuki would become more aware of Sho's efforts and his feelings as the series continues.

Early life
Mizuki and her brother Tetsuro had been friends and neighbours of the Fukamachi family since they were young children. Attending Narisawa High School together, Sho and Mizuki worked with each other on the student council; Mizuki was the council's Vice-President while Sho served as Secretary. During this time, Sho had become strongly attracted to Mizuki, though Mizuki was unaware of this and harboured romantic feelings toward the student council President, Agito Makishima.

Pre X-Day
When Sho and Tetsuro accidentally discovered the Guyver unit and became targets of the sinister Cronos organization, Mizuki remained oblivious to the pair's struggles for a time. While Sho and Tetsuro had disappeared from school on occasion, they made up excuses to protect Mizuki from the horrific truth that they were being threatened by monsters in human form. Mizuki would soon discover the truth when she was abducted by a Zoanoid and both Guyvers I and III came to her rescue.

After her kidnapping, Mizuki spent some time in hospital to recover from the shock. Tetsuro tried to convince her that the creature she had seen hadn't been real, that it was just an actor in a suit and that she had wandered into a movie shoot. Mizuki didn't believe this story and continued pressuring her brother to tell her the truth, but in the days to come she would become irrevocably involved in the struggle against Cronos as the organization once again targeted her and Tetsuro in order to use them as bait for Sho.

Some time after the fall of their Japan branch, Cronos kidnapped Mizuki and Tetsuro as well as Sho's father Fumio. They were taken to Relic's Point, Cronos' primary research facility located beneath Mount Minakami, where they witnessed how Cronos developed their Zoanoid soldiers. Finally, Tetsuro admitted the truth to Mizuki who was deeply shocked and distraught to find out that Sho had been fighting to protect her all this time. Fortunately, she would not remain a prisoner for long as Sho and Agito later broke into Relic's Point and rescued her, Tetsuro and Fumio. While the Segawa siblings were taken to Yohei Onuma's cabin in the woods for their safety, Fumio was recaptured by the Hyper-Zoanoid Team Five.

While Sho and Agito would return to Relic's Point to save Fumio, Mizuki remained at the cabin where she befriended Yohei's granddaughter Shizu. Having discovered that Agito was also a Guyver and learning that Shizu and her family had served the Makishimas, she asked her about her life with Agito, hinting toward some possible jealousy. Shizu told Mizuki about how she had been a part of Agito's life since childhood and how she had completely dedicated herself to serving Agito in all things. This deeply hurt Mizuki as she felt she didn't really know Agito at all and couldn't possibly compare herself to Shizu's single-minded devotion to him.

Later, Mizuki would learn that Sho had killed his own father after Fumio had been turned into a Zoanoid by Dr. Barcas. Her despair would deepen after this as Masaki Murakami revealed what he knew about Cronos and also the origins of the human race, explaining how mankind had been engineered by an ancient alien power as the basic model for a new breed of biological weapon. Unable to accept the idea that all life on Earth had been created as part of some alien experiment, Mizuki ran away from the group, fleeing into the forest. Sho went after her to try and calm her down and bring her back, but the trauma he had suffered as a result of killing his father had left him unable to bio-boost, leaving him and Mizuki defenceless against Cronos. Sure enough, a group of Zoanoids found them and almost captured them, but the two were saved by the timely arrivel of Guyver-III. However, this was not Agito but was, in fact, the Lost Number known as Aptom, who had only saved Sho so he could have the pleasure of killing him himself. Aptom tormented Sho by forcing him to relive the repressed memory of slaughtering his father, then proceeded to morph into Enzyme II, the Zoanoid that Fumio that been turned into. Holding Mizuki hostage, Aptom repeatedly slashed Mizuki's clothing, threatening to tear her apart unless Sho could transform into the Guyver. This sadistic tactic succeeded and Sho was able to reactivate his armour, freeing Mizuki from Aptom's clutches and defeating the twisted mutant in battle, seemingly killing him. Having seen the lengths Sho had gone to to protect her and the pain he had endured to do it, Mizuki came to realise how Sho must have felt about her all this time and realised she felt the same way about him.

Mizuki hadn't been harmed by Aptom, though her clothes had been shredded, so Sho offered her his shirt until they could reunite with their friends. With the group's campsite devastated after an attack by Richard Guyot, their status was left unknown, so Sho and Mizuki decided to head for a populated area in the hopes that Cronos wouldn't risk attacking them with so many witnesses around. They arrived in the village of Takeshiro which seemed to be rather peaceful, but Mizuki and Sho were horrified to discover that all of the townspeople had been turned into Zoanoids and had been enthralled by Dr. Barcas. The townsfolk transformed and attacked Sho and Mizuki, but because they weren't in control of their actions Sho was hesitant to fight back. Soon, Mizuki and Sho were surrounded, but were saved by the timely arrival of Agito. Unlike Sho, Agito had no qualms about killing the Zoanoid villagers and slaughtered them all, arguing to Sho afterwards that the villagers were beyond saving and so he had granted them a quick, painless death. Seeing this side to Agito caused Mizuki to re-evaluate her feelings towards him and she no longer held any kind of romantic interest in him.
