struggling to survive. Only those with the best mastery
of Reikijutsu can become their disciples and serve huma-
nity as guardians, protecting it, maintaining its peace,
and expanding human territory.

is shrouded in mystery, these guardians are the only
hope for humanity to survive and thrive, In this new world
now known as Rereikai.
