The Shichiseiken is revered as one of the treasured tools of the Sage of Six Paths. All five of the tools consume enormous amounts of chakra when used, so much so that normal humans would die after using the tools for only a short period of time. When the tools later came into the possession of Kumogakure, only the Gold and Silver Brothers due to their large chakra reserves were able to wield the treasures without fatal repercussions. When not in use, Kinkaku stored the sword within himself, drawing it from his own mouth when needed.
