In "Digimon Frontier," Takuya Kanbara is the main character and leader of a group of human children who are given the ability to transform into Digimon. He receives this power at the beginning of the series, along with the "Spirits of Flame." Takuya is in fifth grade (sixth grade in the dubbed version), and his story begins when he gets an SMS message on his phone while celebrating his brother's birthday. The message instructs him to go to a subway station, where a Trailmon takes him and four other children into the Digital World. Initially, Takuya is energetic and athletic but tends to act without thinking and can be stubborn. He has a strong sense of justice and tries to use his powers for what he believes is right. His hot-headed personality often leads to arguments with Koji Minamoto, another main character. However, they learn to respect each other after their first encounter with Duskmon and become good friends and partners in battle. Takuya also appears in a special chapter of the Digimon manga V-Tamer 01, where he teams up with Tai to fight Metamormon.
