Takuya Kanbara

In the anime series Digimon Frontier, Takuya Kanbara is the leader of the team, chosen to wield the Spirits of Flame that hold Ancient Greymon's power. Takuya begins as a typical goggle boy, a member of his school's soccer club. He is at home sitting at the table just before his brother Shinya's birthday party when he receives an SMS message from a mysterious voice, which is later revealed to be Ophanimon.

Takuya has a strong sense of justice, and tries to do the right thing. He is energetic and athletic, tending to act without thinking first. Takuya's hotheaded personality generally ends up in him arguing with Kouji Minamoto, but eventually they put away their differences and became friends. Takuya acts like an older brother to Tomoki Himi, who reminds him of Shinya. He also has a liking for Izumi Orimoto, though he never admits it.
