Mustang

Mustang is a really poor boy living in a cramped apartment, trying to  make ends meet at Squid Target. When not working, he enjoys playing the  guitar; being something that was taught to him by his parents, it makes  him feel closer to them, since he can't currently afford to take a trip  to see them right now. Despite his living situation, Mustang isn't  unhappy; he meets with friends during turf wars whenever he can, and he  often plays guitar outside for people to listen to. His pride prevents  him from setting out a cup or hat for people to leave money for his  performance.

A bystander watched from afar until Mustang, hungry and dehydrated, collapsed  mid-song. The kind listener drove him to the hospital and even paid for  his bills, but Mustang was distraught waking up, now owing a debt to a  man he has never met, and only having a name to go by. He played guitar  more often, stopping passerby hoping he could find this man, until the  day they formally met. Mustang still feels indebted to this man, but  enjoys his company dearly.
