A balanced team: a little sister type character and a big sister type character. An emo looking long hair dude, and a cheery looking spiky hair fellow.
I guess Yuusuke based his choices on those very characteristics. The older guy is obviously there for the more mundane reason of needing someone with experience.
@Kaarme XD I'm on the old guy and that unusual type for me to like for me ... The reason this manga look more about strategy and political and he looks the most useful and strong one and his look not that bad XD
Beside I properly likes all the characters appeared until now. XD
The princess is kind of annoying, I hate pushy people. Makes no sense to join the kingdom though, he doesn't even know how it works, didn't even look at other options. Is he secretly a busybody?!?!? >:0
