Ryuseimaru

The Fu-Ma Twin Blade Ryuseimaru (封魔双生刃流星丸) is Taki's primary weapon when donning the GalaxyArmor. In Taki Gaiden: The Kunoichi Who Leapt Through Time, it evolves from her two signature dual kodachi, Rekki-Maru & Mekki-Maru, once assuming the aforementioned form.

Design

 * Ryusei Edge (流星エッジ): The blade of the weapon. By channeling pressurized energy to the blade, it creates a resonance vibration that allows the weapon to cut through anything. When a Time Charge is initiated, the blade goes into its overload state and vibrates to the natural frequency of the enemy to destroy it.
 * Rekki-Maru (Long) (裂鬼丸（長状態）): The long blade part of the weapon evolved from Rekki-Maru.
 * Mekki-Maru (Short) (滅鬼丸（短状態）): The short blade part of the weapon evolved from Mekki-Maru.
 * Grip Connector (グリップコネクター): An interface link system that connects with the Rider suit through the grip of the handle. This allows the Ryuseimaru to receive battle data to optimize its systems for the user. In situations where a Riderwatch is inserted, the Grip inputs data of the Ridewatch directly into the user's suit, allowing them to understand how to use it in battle.
 * Strike Sensor (ストライクセンサー): The weapon's motion-sensor mechanism in place of a trigger-mechanism. The swings executed by the user delivers energy to the Ryusei Edge blade for attacks.
 * Meteo Ryūzu (メテオリューズ): The special attack mechanism. By pressing the Meteo Ryūzu, the Time Charge will start, allowing Taki to execute basic finishing attacks. However, if a Ridewatch is installed in the Ridewatch Slot, a special finisher is initiated, harnessing the powers of the Ridewatch.
 * Renketsu Joint (連結ジョイント): The connection mechanism of the weapon where Rekki-Maru (Long) and Mekki-Maru (Short) are connected during in Gattai Mode.
 * Ridewatch Slot (ライドウォッチスロット): The input module for Ridewatches. By inserting a Ridewatch into it, the weapon can power up for finishers.
