A human soldier and lieutenant in charge of the Clydesdale Platoon. During the first Earth-Mars War, his platoon consisting of many tanks were no match for the Martian's weaponry and Kataphrakts. He was forced to shoot his own best friend, [John Humery](https://anilist.co/character/88444/John-Humeray), that was trapped inside a burning tank after being frozen in fear. As a result, he developed PTSD after the first war. After experiencing the devastating defeat, he claims that the weaponry and machinery on Earth are no match for Martian technology but no one believes him. He becomes an instructor at Shin-awara High School during the second Earth-Mars war.

Kouichirou is a stubborn and carefree adult who often takes his work seriously. He is often seen slacking, drinking or being sarcastic towards his students. Due to his PTSD, he greatly regrets being unable to save his best friend and traumatizes over the past as he is not able to forgive himself. 

Although he does not look like a reliable person, he is very skilled when it comes to piloting Kataphrakts.

In 1972, the Apollo 17 mission found a hypergate to Mars on the surface of the moon. Upon landing, astronauts discovered a enchanted utility later referred to as 'Aldnoah', giving the astronauts a status of superiority. Soon, many humans have relocated to Mars, and have adapted to the name 'Martians'. After Princess Asseylum, a royal Martian princess, descends onto Earth in an attempt to create a treaty between both planets, a war breaks out between Earth and Mars, and Martian soldiers begin to descend from the sky, riding steel giants, intent on exterminating humanity.
