Sin (GUILTY GEAR)

Sin is another of the seven unique playable characters in playable in Guilty Gear 2: Overture. He is son of the king of Illyuria: Ky Kiske, though was left in Sol Badguy's care because of the exploitable fact of his Gear cells may be known to the public. He bears grudges towards his father for neglecting him because of his duties as a king.
Though Sin is at most 5 years old, he has the appearance of tall boy in his late teens- making it hard to notice his rash, child-like behavior. Through Sol's (a knowledgeable man in fighting himself) training Sin has grown into a very strong child- even being able to harness the power of a reddish lightning magic like his father (whose lightning is blue). Sol's teaching also included weapon fighting which even Sin is was able to pass and even now uses a flagpole as his main weapon. Sin's potential is very dangerous when it comes to life; because of his Gear genes he may one day be feared as he can be used for war purposes. Because of Sol's age, Sin usually calls him by the name Old Man.
According to the 50 Question Interview at the GG Overture Materials Collection Book, aside from fighting, the only thing Sol is able to teach Sin is to read and write.
