A sword which is currently in the Japanese royal Regalia, supposedly from mythical times. It is often depicted as a [[katana]] in fiction, however the most reliable images show it as a older form of short sword.

In the [[Touhou]] fandom, [[Morichika Rinnosuke]] is believed to have it in his antique shop and some artists depict it as his weapon of choice. Canon only states that it was discovered in [[Kirisame Marisa]]'s hoard and was renamed "Sword of Kirisame" "(霧雨の剣)":http://dic.pixiv.net/a/%E9%9C%A7%E9%9B%A8%E3%81%AE%E5%89%A3 in [[Curiosities of Lotus Asia]]. 

In [[The King of Fighters]] series, the main character [[Kusanagi Kyou|Kusanagi Kyo]] holds the weapon inside his body, so as to make him be able to wield flames and seal Orochi.

In the [[Len'en]] series, [[Adagumo no Yaorochi]] was born from Orochi's severed arm and because of this, [[androgynous|he/she]] has a connection with the sword, whose real name is [[Tasouken]] (蛇叢剣).
