Takeshi is a young man of above-average height, with broad shoulders and an athletic frame. Though he has an appearance that would be described, by others, as unremarkable, when the idea of a duel excites him a certain intensity haunts his gaze. His features are fairly narrow, despite his more broad build, likely due to not being particularly athletic.
Typically Takeshi will wear his school uniform, or something similar to it, cutting the look of a traditional student, though he often doesn't wear the jacket buttoned up, and in this most recent year has taken to wearing his tie loose, as well as less-kempt hair than in previous years.

In this world it's often assumed there's two types of people, those who have to work hard and study/fight for what they want to achieve, and those who seem to be able to do so by intuition. Though Takeshi gives off the impression of the latter, being a strong duelist for his age, the case was that he was once extremely disciplined and regimented as a youngster, while learning to play Duel Monsters.
Be it stress, age, or some unquantifiable factor, for the last some months Takeshi has become something of an over-lax goof-off in his third year, frequently sleeping in and blowing off studying in favor of finding duels to keep himself occupied.
Despite this, he seems to be doing fairly well in his academics, and is rarely caught off-guard in his duels.
Takeshi is usually pretty relaxed, often using casual language and greeting others with a warm, protective energy. He often makes friends with his underclassmen because of a paternal instinct that he seems to possess. 

Your character's history would go here! As always, be careful with this. It shouldn't be too shallow and should touch on every important period in your character's life, including the reason as to why they're attending Liberta Duel Academy.
