"Is it possible that I could become someone like Crysta someday? In addition to his ability it was amazing turned out to be useful for himself and others. I want to have such an ability," in him Anko said hopefully and thought, 'What good is it to have a metal element?'
Anko who was still hesitant to consider this ability that he had tried to think about it many times. He didn't really know the usefulness of metal and he thought it was easy to rust when exposed to water. For him who had fought with Mafu felt that his strong-looking ability would be his shortcoming when in a fight with the water element.
Anko was not confident that his ability was good, which is clear some people in this isekai admitted that his ability was one of the strongest elements. It is said that if someone has a metal element is a person who has a strong throat.
