Hiiro wants to get the Grand Trowa so that he can defeat the evil dragon, Dagon Zot.  But first he has to find Nambuuko, the evil arms merchant who has it. And before he can do that, he needs to find a place to eat!
It's probably because we opposed Nambuuko.
ربما لأننا عارضنا نامبوكو
Das kommt davon,
sich gegen Nanbuuko zu stellen.
Debe ser porque nos opusimos a Nambuuko.
