Naoto Kurogane (ナオト＝クロガネ), also known as Naoto Terumi, is the servant of Raquel Alucard and heir to the Terumi branch of the Amanohokosaka Clan, signified by his ownership of the Eye of the Hunter. Naoto is the older brother of Saya Terumi and a cousin to Haruka Hayami. Naoto was sent from his possibility into that of the BlazBlue world to save his own world.
Has a rough personality. Due to owning the special power of the "Eye of the Hunter," he has experienced many hardships, and he deeply wishes to lead an ordinary and peaceful life. However, because he has a strong sense of justice and can't help but assist those in trouble, he sometimes gets himself tangled in problems. He's not afraid of acting, but often does so before thinking. He's a little too loud for tea.
Powers and Techniques
Naoto was taught by his mother in the way of her family's martial arts, excelling in them. As a member of the Amanohokosaka Clan, he is also versed in exorcism, but is nowhere near the level of the main family.
There are two powers that truly define Naoto - the Eye of the Hunter, and his Drive, Bloodedge. The Eye allows him to see the life-force of every living thing - be it human, Kaka, vampire, or otherwise. Having had the Eye for all his life, Naoto can read the runes that the values are presented in and can gauge the health and strength of others by reading them.
Bloodedge is Naoto's main weapon and he uses it frequently to fight his opponents. By using his own blood and hardening it, Naoto can create various weapons to fight his enemies. His arsenal usually includes a katana, a two-handed axe, a large scythe, and an extendable amount of blood that he uses in a fashion similar to a whip. Whenever Naoto uses his Drive, his hair turns white and his eyes turn red, but as of Central Fiction, this is only the case when he truly taps into his power to fight. He can create many shapes with his blood, even making a head similar to that of the Black Beast.
Because of his contract with Raquel, Naoto borders on the immortal, but only when she is around. They share the same life-force, and hers is far and beyond more than most humans. This gives Naoto an ability normally unique to vampires called Regeneration, which means that all wounds sustained will patch themselves up effortlessly. Because his right arm is made from vampire blood and thanks to the sorcery installed in it from Clavis, Naoto has the physical strength of a vampire - this was easily demonstrated when he killed an Apostle with a single blow. For an unknown reason, Naoto can subconsciously create fog from his body to replace missing limbs.
As strong as Naoto is, he still has weaknesses. Without Raquel, Naoto loses Regeneration and his right arm disintegrates back into blood. He is also a three-time amputee, and his replacement limbs have some movement restrictions. Naoto also has a lack of real fighting experience and relies heavily on his Drive to fight tough opponents, which can make him predictable.
A foreign body that entered this world, searching for a woman named Raquel Alucard.
He possesses a unique power, 'Eye of the Hunter' that allows him to see the streams of life. His drive is 'Bloodedge,' which turns blood into a weapon.
When he wakes up in the unfamiliar land of Kagutsuchi, he is at a complete loss. Without knowing left or right, he wanders town looking for a 'blonde, pale young girl with ribbons that resemble rabbit ears.'
