ミンジャラ

An artificial god that was created as a weapon 700 years ago.
Since he is an artificial god, the "one Tenken per person" rule doesn't apply, and can still form a contract by ignoring the rules (double Tenken).

Tenken is power obtained by forming a contract with God or Spirit.
Only one person can have one Tenken and there are various kinds of Tenken in the world.
Spiritual power is required to be able to use Tenken.
