The GREAT DESTINY Legend reveal... meh. Sure, we knew where Arata himself was heading from nearly page 1 (well ok, maybe from volume2 onwards at most), but it still doesn't quite explain the Princess part of the power mechanics
Wouldn't be Watase series w/out some jokes done fanservice-style & at least one chara pretending to be the opposite gender, nope (which again, could have used more explaining)
