Jack

Jack is the main protagonist of the fanfiction story Air Gear: Crossroads. He is the current Flame King, which he attained after beating his old friend and rival Donald. He is also the older brother to Yuki, and has custody of his younger sister following the death of his parents.

Personality
Jack is seen to be a very calm and confident individual, and is seen to be quite caring of his younger sister Yuki. Aside from this he is seen to be quite serious and shows very few emotions, which is more likely caused by the death of his parents when he was ten years old, to which his sister was a baby at the time.

Trivia

 * The top part where it says Air Gear: Cross Roads is just something I made of the top of my head, and it may not come to fruition, nor will I write anything about it.
