A combination sword and whip. Usually, this is a sword that splits into sections connected by an internal string, but can also apply to an extremely flexible sword.
Only use this tag if the whip nature is shown. Do not use it if the weapon is only in normal sword form. Do not confuse this tag with chainsword, which is a sword with moving chainsaw parts.
Pixiv tags are 蛇腹剣 (lit. accordion sword) and ガリアンソード (Galient's sword).
