In the anime series, when Kenshin's eyes change to reflect his psychological reversion to Hitokiri Battōsai, their color shifts from violet to gold.
As such, he has a tendency toward trying to solve problems all by himself and alienating his would-be allies with secrecy so as to keep them from becoming involved in his risky endeavors.
Having lived his own life carrying heavy regrets, Kenshin is reluctant to judge others for their personal actions, beliefs or mistakes and always offers hopeful encouragement so that those who have stumbled onto the wrong path might redeem themselves in the future.
He carries himself with an air of amicable temperance, politely conversing with the people he encounters and freely giving his meager services to those who need a hand.
Kenshin doesn't hesitate to put himself in the path of harm to shield those around him and often attempts to diffuse contentious situations with soft, calming words and a somewhat clownish personality involving feigned clumsiness and his trademark interjection "oro" (a unique pronunciation of "ara").
Despite this, however, he holds his own existence cheap and carries in his heart a grievous guilt that prevents him from becoming emotionally close to the people around him and compels him to a life of humble service and selfless personal sacrifice.
Even with his prodigious skill as a prolific swordsman, Kenshin refrains from wielding his great combat strength for his own sake, drawing his sword only for the well-being of others when words fail to appease.In a redesign for the kanzenban, Kenshin's scar has been altered so that the lateral scar is longer, stretching across his nose to just below the inner corner of his right eye.Kenshin dresses simply, wearing a plain men's kimono of cheap, worn cloth with a white umanori hakama, zori and white tabi.However, when forced to draw his sword against those who abuse their power and undervalue the lives of others, Kenshin's calm temperament gives way to a marked intensity capable of intimidating even other skilled swordsmen and can go so far as to become a powerful fury, despite his compulsion toward diplomacy.But when his strength as a rurouni is insufficient to defend against a particularly threatening foe, Kenshin's restraint falters and his personality reverts to that of his days as the Hitokiri Battōsai.As a teenager, Kenshin was impertinent, idealistic, and often easily embarrassed or flustered.
