Ikoma

Ikoma (生駒, Ikoma) is the main protagonist and a young steam smith who makes a living in Aragane Station working with steam engines. He and his friend Takumi developed a steam weapon called "Tsuranuki Zutsu" which Ikoma believes is the best way to fully destroy a Kabane.

Appearance
Ikoma is a bespectacled young man of average height and build. He has golden-brown eyes, and messy, light green hair. After being first bitten by a Kabane, his hair partially turns white due to the virus. His glasses are missing a lens on the left frame while the lens on the right frame is tinted green.

Ikoma often wears his steam smith uniform, which is considerably torn after his first encounter with the Kabane. In order to stop the Kabane virus from spreading to his brain, he bolts and brands a shoddy harness to his body, which encompasses his right shoulder and some of his right torso. He also wears a tight collar around his neck, which helps keep the virus at bay.

Personality
Ikoma is determined and foolhardy, his eyes set on making a difference in humanity's fight against the Kabane. His outstanding willpower to fight the Kabane and do the right thing often puts him in tough situations, but is also his best survival mechanism.

His greatest desire is to destroy the Kabane once and for all, which began after he witnessed the death of a loved one at their hands. However, he also maintains a keen sense of justice, prioritizing the lives of others before his own survival. After he survives being infected, he is elated at the fact that he could help others who are bitten as well.

Ikoma is a proud character who maintains his honor in spite of adversity, which clashes with his inherent desire to help others. It is because of this that he lives on to protect others aboard the Koutetsujou, despite the danger his existence poses for everybody.

Ikoma is also a tinkerer, born from his work with steam engines. He develops the Tsuranuki Zutsu with help from Takumi, which is the only known weapon that is able to pierce the caged heart of a Kabane in a single shot.

Powers and Abilities
As a human, Ikoma is rather intelligent and thinks well on his feet. He is a good enough engineer to design the Tsuranuki Zutsu, and thinks quickly enough to stop the Kabane virus from spreading with scrap parts around his smithy. When under pressure, Ikoma is shown to have high pain tolerance, as he withstands bolting his metal restraints to himself and slicing his wrists.

As a Kabaneri, Ikoma's strength, physical resistance, and endurance is greatly increased. He is able to hold and bend a scalding hot pipe with his bare hands with no indication of pain. He then takes a bullet to the chest, but goes on to fight through multiple Kabane. His wounds also appear to regenerate quickly as a Kabaneri. Similarly to Mumei, he wears a restraint around his neck in the form of scrap metal, which presumably helps restrict the virus from entering his brain.
