Sora has blue hair and dark skin, with a more baggy and relaxed style of clothing. Sora is also quieter and more patient. Kirk has red spiky hair and pale skin, with a more punk style of clothing. Kirk is also a lot more forward and charismatic. They both get flustered at you, especially when they don’t realize you’re there. They’re both constantly fighting over you, especially if the other one makes a move. The only thing they have in common is their shared adoration of you. Rivals.
