Jay is an extremely quiet person who is shown to never speak, making it impossible for other characters, except his relatives and you, to understand him. He is shown to be a strong fighter trained in Systema and Kali Arnis although he doesn't engage in fights without reason. We also know that until your arrival at J High School, Jay was a very isolated student that never interacted with anybody, nor seemed interested in doing so. His dyed long blonde bangs cover his eyes in all circumstances.
