Kyoya Tachibana

Kyoya Tachibana (立花 恭也) was one of the Otherworlder summoned to serve Falmuth.

Personality
Kyoya was a laidback individual, believing himself of having one of the most powerful skill.

Unlike the other summoned Otherworlders, he was willing to take a more flexible approach to his plight. There was nothing he missed about his old world; he was far more interested in the powers obtained on the new one, having become incredibly arrogant and self-confident due to possessing superior abilities in comparison to the average people born in the new world and beneath his regular approachable persona, Hakuro noted that Kyoya was no different to Shogo, as he was sadistically taking pleasure in killing the innocent and defenseless civilians of Tempest.

Kyoya believed he was as powerful as Hinata Sakaguchi. Due to immense power and unique skills most Otherworlders typically have after being summoned, Kyouya was shown to have developed an overinflated ego and an immense sense of arrogance, believing that he was the World's strongest despite not actually fought anyone of truly noteworthy strength and power to truly put his power to the test. Its due to this arrogance and bloated ego that lead to his death against Hakurou as he refused to acknowledge that he was weaker than the latter or even the possibility that Hakurou had superior skills and abilities than him.

Kyoya was also very rude. He was always seen insulting Hakurou and said that there was no reason to respect him for just being older him. He had a tendency to mock his opponents, something that was shown on his second battle against Hakurou, laughing because he thought Hakurou was doing a futile effort on trying to defeat due to his Unique Skill.

As seen from his general demeanor and character, Kyoya himself shared several traits with Shogo and Kirari, namely their childish and immature view of the world, selfishness, narcissism and arrogance.

Background
Kyoya was summoned as a living weapon and was forced to serve Falmuth with a cursed spell. Before he was summoned, he used to practice fencing.

He was recognized as the best swordsman in Falmuth thanks to his combined natural talent and newfound skills, due to this Kyoya has become incredibly arrogant and conceited as he had even begun believing that he was superior to everyone else in the new world and even believed that he surpassed the likes of Hinata Sakaguchi with his skills.

Story
Kyoya was ordered to provoke Jura Tempest Federation together with Shogo Taguchi and Kirara Mizutani and managed to kill several of Tempest's citizens. He wounded Gobta and Hakurou during the initial attack and killed Gobzo while laughing, according to Shuna's words. One week later he was guarding one of the crystals that maintained the barrier over Tempest. He fought against Hakurou one more time, during the course of the battle Kyouya was extremely arrogant and continuously refused to admit that there could be anyone one stronger than he that ultimately contributing to his death and defeat by having his head easily sliced off by Hakurou.

After being decapitated, Kyouya started to wonder why his Thought Acceleration skill wasn't wearing off despite having his head separated from his body. Hakurou then proceeded to tell him that their battle was over and to reflect on his evil acts during his final moments.

Hakurou brought along his severed head as he made his way to Geld, where he would then toss it to show Shogo what happened to him.

Later Folgen and Razen would mock Kyouya due to his arrogance into believing that he was one of the world's strongest to Shogo after they revealed the true reason to him, Kirara and Shogo's summoning.

Abilities
Kyoya trained as a fencer in his previous life before he was summoned. His style of fencing was very childish, often going to the offensive without guarding himself because of his All-Seeing Eye skill or doing dirty tricks using his Spatial Element skill. As noted by Razen, Kyoya's skills themselves are indeed impressive, but are stated to be wasted on him due to his lack of genuine skill and talent, leading him to hope that Kyoya could die in front of Folgen to give him the skills and put them to better use.
