"Each type of element can only contract with one Magic Beast, but not permanently. If summoners encounter a more powerful Magic Beast, they can rescind the contract and tame another stronger Magic Beast of the same element. This is also the fundamental reason why summoners can constantly be powerful. And yet, the consequences of the termination of the contract are different."
"Once a master-servant contract is terminated, the summoner will suffer huge damages and it's very possible that the Magic Beast, which forcibly terminates the contract, may eat its master. However, the equality contract won't cause any harm to the summoner and there won't be a situation where the Magic Beast eats its master. Kid, do you get it now? Being a summoner is actually a dangerous and powerful path."
