Kenshi is a 17-year-old young man with average of 178 cm, shared same age and height with his following classmate Daito. He has a fair skin that too smooth to touch him. He is the best known as a genius due to his high rate intelligence of 300-IQ and has a icy young-looking face. He sports medium blue hair that is short. He has a thick fringe that covers the right side of his face. He has a powder blue eyes that makes him looks cold.

Kenshi's default clothes of choose is a midnight blue suit outfit. Underneath his outfit, he wears a denim blue shirt with oxford shoes. He wears a silver-chain belt around his pants, blue wristbands for both hands, and silver ring on the right side of his middle finger. He bears an indigo choker inlaid with snowflake, much like Daito's. Kenshi's trademark trait is a black turtle shell glasses with a power hi-tech that used for analyzing and reading too.

At a days of school, Kenshi wears an official Hakujitsu school uniform with blue necktie for male students. He wears a black glasses to keep his sense good while he reading.

In Kenshi's route, when he recall the wrecking ship of Mercury Valeria in Pulse Crystal Point (hidden base in anime), Kenshi's hair begin to glow in pure white because of sadness past. His torso become almost crystallized like a jewel due to being influenced by Emilien's chemical reaction. His eyes become pure white. Hatred and vengeful by traumatic memories, Kenshi lets out a mournful, agonized scream and cries in pure revenge that even lost his sense of emotions.

In his bad ending, Kenshi's body has become completely jewelled. His entire body now crystallized in blue all over his skin and his hair has grown longer in pure glowing white. In his eyes, his sclera are also crystal-clear while his iris are of a white tint. His teeth are too much sharp, almost like fangs, and has long claws on his hands which are bound behind him. He does not wear his favorite blue suit anymore but rather a white robe-like garment in its place. Like Daito, the robe falls to the sides exposing his torso. Kenshi has lost the ability to speak properly, saliva dripping from his mouth often, and is in a constant state of sad and rage due to Momoha failing on purification.


Kenshi is just average and stoic handsome young man, who shown to be more commitment. He's usually can reacts to no pain whenever he hurts.

Because the voice of ocean brings a good luck for everyone. He's more friendly with his childhood friend Daito and often trained together whatever dangers comes forth. Like Daito, he shown to be more romantic with Momoha and often datings at swim pool for swimming and playing around.

Despite his good morals and good faith, Kenshi holds a sad face and has a strong grudge against Emilien Richelieu after he killing his mother and sister in event of Mercury Valeria's wreck. But he does his best to hide his grief in order to live a better life with Daito or his girlfriend Momoha.

Kenshi is more alike an egghead and his passionate for reading and studying about whatever he like. Momoha points out that he is the best student in the school for getting a high scores in all school subjects. In main route, Kenshi uses Neptune's Mercury Visor to located on where Momoha is held captive.

In the other side, Kenshi is shown to have a weird habits; it is shown to masturbated himself without everybody's knowledge. But only Momoha who can reacts him doing this, she will passed out and forces herself to given a full forced kiss and touch on his body as a punishment (though it has been removed for Re;match or never happen in anime). Although he blamed himself for acting dirty, Kenshi realizes that he loved her dearly in good ending, especially after he rescuing her from Emilien's mind-control. In romantic ending, he proposes Momoha on the Valentine's Day and they're getting married and lives together at Netsuhana Beach house.
