Tristan Mathias, younger twin to Percival. Enthusiastic and energetic, Tristan believes the world is an oyster to anyone and everyone with the motivation to crack it open. He enjoys people and socialization, being far more outgoing than his fraternal twin. He trusts others easily, putting his faith and love into them and dedicating himself even as his brother advises against jumping into such things. This leads to misjudgment, time and time again, and despite that he always bounces back and continues with the pattern.

Curious, intuitive, and eager to learn, Tristan tries to make the best of every situation, unlike his brother, who did the majority of the hard labor when they were back in Haiti, while he did errands and more laid-back jobs to help out. He idolizes his brother but cannot understand why he's so jaded to the world. He has a strong sense of family and friendship, and when seeing someone in need, he will not hesitate to come to their aid.

At times he can be overemotional and clingy, and many don't know how to deal with his erratic moods and tendency to fall in love easily. Percival chides him in this endless cycle, merely trying to improve his younger twin's wellbeing.
