So his actual spirit is some ruler of spirits and his current spirit is some kind of extra filler because he couldn't summon the super spirit? Or did the super spirit call for help through the contract with the small spirit?
Went back to ch1, his friend girl has an air spirit, why are all the OP spirits called as fails, have they ever heard of research?
"oh noes he got the power to control plant life, better not try to improve our farms with this, it's a fail. Oh noes our soldiers have no food because the land is dying, too bad we don't have anyone with magic to magic this problem away because we don't write down what "failures" can do."
"oh noes she got the power to control the air, this clearly wont let her do anything useful like flying or suffocating me by flicking a finger or crushing me by compressing the air around me or making various inhospitable places breathable and usable, like putting out fires, defending against airborn poisons/pathogens fucking whatever, omnipotent much? nah this is a failure"
