Tranquil Rhapsody

Tranquil Rhapsody is Sixth Serenade's signature PRI-ARM weapon. It is forged from the 5* weapon Tranquil Arias.

Description
The PRI-ARM form of Tranquil Arias, a mysterious weapon developed by St. 1504 Labs of Schicksal. The entire project was conducted under the direction of the Schicksal Overseer. According to the researchers involved in the project, this pair of dual pistols demonstrated incredibly advanced performance that must not belong to the modern era. It enslaves darkness and unmasks all sins with its luster – it is the dominator of the night.
