Tazuma Claire

Claire (暮亞 (クレア)) is a Gemstone and a member of the Kamisato Faction.

Appearance
Claire has long, tied back black hair and wears thick glasses. She also wears a white apron-like dress which leaves her back bare. She would look plain and inconspicuous, however she has giant tropical flowers blooming on either side of head and even more colorful flower petals adorning her back.

Personality
Claire is described as a 'teacher's pet' and presents herself politely, however behind this she is somewhat perverted, something she denies, sometimes forcefully. As with other members of the Kamisato Faction, Claire tends to respond negatively to those who harm or slight Kakeru.

Background
Claire was part of the same school that Kamisato Kakeru attended and was a normal student like him. She was part of the gardening club. According to Kakeru, she only gave him quiet greetings whenever he entered the close room and he described their relationship as not being close enough to eat lunch together. Some event happened that involved Kakeru presumably saving her, apparently involving her running right into him on turning a corner while outside and nude, which caused her to fall in love with him and join the Kamisato Faction.

World Rejecter Arc
Late on December 3rd, Claire and Elza arrived at the apartment which the Kamisato Faction were using as a safe-house, not long after Kakeru's encounter with Sample Shoggoth-infested Patricia Birdway. Learning of the situation from Ellen, they recognized the usual pattern that they were familiar with regarding Kakeru and girls. Despite the problems at hand, the trio of girls ended up doing their own thing and dragging Kakeru and Patricia along with them, going to a public bath and then eating out after botching dinner. However, later that night, when Kakeru managed to persuade Patricia to let him help her, the girls resolved to help as well, together with the assembled Kamisato Faction.

Claire and Elza were both present during the initial ambush and negotiations with Kamijou Touma, using her vines to ensnare Touma and drag him before them. As negotiations broke down, she launched an attack against Touma after he rejected Kakeru's reasoning and called him an idiot, but it was negated by Imagine Breaker. She was also present for the subsequent attack on the Kamijou Residence by the Kamisato Faction. When Touma came up with an alternative solution to Sample Shoggoth which involved using Claire's abilities to replace the fat Patricia had lost to the parasite and displace it, Claire reluctantly helped him. However as the injection was progressing, Sample Shoggoth started to lash out, forcing Touma to use Imagine Breaker to protect Claire, disrupting the surgery and eliminating the parasite prematurely. After Nephthys sacrificed herself to save Patricia, Claire and the rest of the Kamisato Faction stood back as Touma and Kakeru faced one another.

Abilities
Claire's ability as a Gemstone is the manipulation of plant-based matter. According to Kamisato Kakeru, her body cells are closer to plant cells than animal cells. She can violently amplify the bonds of algae and fungi and she can absorb metal or plastic to use their traits, allowing her to devour a modern weapon and construct a missile or chainsaw out of nothing but plants and flowers, or even combine or rearrange them to create something brand new like a remotely guided chainsaw, though at a higher risk of failure. Her power is more about regeneration than a solid barrier, which makes her perfect to act as a shield. Her ability can allow her to survive being bisected and reconnect herself, given time.

She can use vines to attack and grapple enemies or create a cushion by weaving those vines like a net. She is also capable of controlling carnivorous plants to ambush enemies. Aside from plant manipulation, Claire's control over plant matter also covers plant fats.

Character Art Design
Haimura created the designs of Claire, Ellen and Elza using the concept of girls who are "twisted in a galge-ish way". Claire was initially designed to have only two large flowers dangling from thinner stems, but this detail was eventually changed to appear much larger than the previous design, which Haimura stated was intentional because the initial design was "too plain".
