An old promise between friends is put to the test as their loyalties and ambitions change. But against Rekka's invincible general, Granedger may not stand a chance.
Kai, you can change the country,
but I want to change the world!
،تستطيع تغيير البلد يا كاي
!لكنّني أريد تغيير العالم
Du kannst das Land ja verändern, Kai.
Kai, puedes cambiar al país,
pero ¡yo quiero cambiar al mundo!
