Papalogia AU All Acnologia wanted to do after his best friend died, was be lonely and miserable and kill some people. However his promise to said best friend wouldn't allow him to. So he just fly's from place to place (still killing, just the bad guys). One day he is forced to land on an island where he meets two girls that leads to him having to join a guild and then about 100 years later he is forced to take care of 5 baby dragon slayers by this annoying human. Why him? (cross posted on ao3)
