|This article is about a/an weapon in Kamen Rider Gaim.|
The Sheimu (シェイム Shēimu) is Demushu's sword (剣 ken) weapon. It resembles a sword with a spade-shaped end on the pummel of the handle, which allows the user to control Helheim flora and fauna. The weapon's balance is perfect, allowing the user to use both ends of the weapon to strike enemies with. It was destroyed by Gaim Kiwami Arms's Hinawa Daidai Musou Zan.
- A promotional image for Kamen Rider Ryugen Yomi's Arms Change figure showed Baron Lemon Energy Arms wielding the Sheimu. This might be a possible foreshadowing of Kaito evolving into Lord Baron, who wields the Guronbaryamu.
