Rasen is a beige, arm-mounted drill used by Pyke, which uses red Fire Dust to fire four cannon shots from its base. The weapon has golden trimmings which lead up to the blade of the drill which is golden in color.
Despite the weapon's name being revealed, as of "The Mission", Pyke has yet to name it.
- "Rasen" is German for the word "race" and the Japanese word for "spiral".
- Rasen is very likely a reference to the anime Tengen Toppa Gurren Lagann which is famous for its use of arm drills and is the favorite anime of Kerry Shawcross, Pyke Rite's creator and player.
