[[suiguutou_(juuni_kokuki)|Suiguutou]] ([b]水禺刀[/b] [i]Water Monkey Sword; Sword of Suiguu[/i]) is a sword that can be wielded only by the rightful ruler of Kei. The sword is accompanied by the [[hekisoujo_(juuni_kokuki)|Hekisoujo]], a miraculous gem possessing healing powers. The sword, along with its scabbard, and the gem are sacred treasures in the kingdom of Kei.

[i]The Suiguutou[/i] was forged by [b]Tatsu-Ou[/b], a previous great ruler of Kei, from a water youma and it was originally known as [b][i]Suikantou[/i][/b] ([b]水鑑刀[/b], [i]Water Mirror Sword[/i]). When Tatsu realized the sword's power could bewitch the wielder, he forged a scabbard to contain its magic. Because the scabbard was made from a [i]long-tailed monkey youma[/i], [[aozaru_(juuni_kokuki)|Aozaru]], the sword was renamed [[suiguutou_(juuni_kokuki)|Suiguutou]] to reflect its new nature. The sword and scabbard change form with each new master; the blade originally took the form of a long-handled scimitar and eventually becomes a long sword for [[Nakajima_youko|Youko Nakajima]].
