I got a question. Does it counter if Issei is considered to be the one time wielder of Thor's Hammer, Mjolnir? Even though he used it once, you can still consider it one of his equipment he used. Consider Kiba, who only used the Ascalon once in the series and never used it again as of now. Is possible to add Mjolnir (or label it as replica) undered Issei's equipment?
