Kazuma Kval

Kazuma Kuvaru is the protagonist of the novel Phase Shift 1 and a major antagonist throughout the rest of the Phase Shift novels.

Information
Suffering from amnesia and hallucinations, Kazuma is unable to remember anything seven years prior (to the start of Phase Shift 1). He disliked physical activities, and preferred to stay in-doors reading. With Relius Clover (his tutor at the time), he apparently traveled the world, then studied at the Magic Guild. Apparently, due to being quiet and disliking the outdoors, some people become uneasy around him, however, he and Trinity Glassfield shared a close relationship that is implied to have been romantic.

In truth, Kazuma was actually a body created by Relius for Yūki Terumi to fuse with (after he was damaged by the Black Beast before the Dark War). During Phase Shift 1, he and Terumi meet, and end up fusing close to the end of the novel. He was later caught by Valkenhayn R. Hellsing and presented to Nine.

When Nine placed the spell Ruby: Mind Eater on Terumi, she didn't take into account that Kazuma and Terumi were still separate entities in their own rights; thus, only Terumi was affected by the Mind Eater, whereas Kazuma was unaffected. His mind now similar to Terumi's due to their time spent together, Kazuma took over his body and acted in a similar grace to Terumi to try and con the Six Heroes into thinking that Mind Eater had truly worked and that Terumi, and Kazuma by extension, were under their control.

With the Six Heroes fooled, Kazuma took the opportunity to prey on Trinity Glassfield. By using the close relationship they had forged in the Magic Guild, Kazuma managed to convince her to release Mind Eater on Terumi by fooling her into thinking that Terumi himself would murder Nine. When both Nine and Trinity were disposed of by Kazuma, they encountered Hakumen and Jubei. After Jubei successfully managed to separate Kazuma and Terumi using his brother Tomonori's Sekigan (隻眼), given to him by Rachel, Hakumen grabbed hold of Terumi, now in his 'ghost form', and fell into the Gate while Jubei closed it. Kazuma's body was left behind and it's unknown what happened to him.

Appearance
Being created in the likeness of Terumi, Kazuma bears a strong resemblance to him, except his bangs hang over his eyes. He wears a standard Magic Guild uniform with a purple ribbon tie and a black cape, along with a matching pair of black pants. He has a very pale complexion.

Personality
He was a kind, curious, and sometimes weird person. His personality is exactly the opposite of Terumi's, but they share the same hobbies. This all changed when Terumi fused with Kazuma, with Kazuma becoming just as warped as Terumi is, no longer caring for even the affection that Trinity Glassfield showed him.

Trivia

 * When Amane Nishiki uses his Astral Heat on Hazama, Kazuma appears. Somewhat humorously, he is seen marveling and observing at the boiled egg he has in Phase Shift 1.
