Mercury Aqua Rhapsody
Mākyurī Akua Rapusodī
Super Sailor Mercury
In the manga, the attack's first appearance was in Act 35. Here, Sailor Mercury used her Mercury Harp to perform this attack and allow her and mother to break free from Fish Eye's spell. She also used this attack in Act 50 - Stars 8 while she and the other Senshi were under the control of Sailor Galaxia's bracelets.
The attack was first used in episode 151, in order to break free from the computer which she and the Sailor Senshi had been trapped by VesVes. To perform this attack, a watery lyre materialized and when she played it, she fired a water blast that could destroy or freeze its target. She usually performs this attack to help weaken the enemy so Sailor Moon can use Moon Gorgeous Meditation to destroy the target.
The attack first appeared in the musical Sailor Moon SuperS - Yume Senshi - Ai - Eien ni..., and there was also performed with the Mercury Harp. In other musicals, however, it was performed without any item at all, similar to the anime.
Mercury Aqua Rhapsody appeared in several video games, such as Sailor Moon SuperS: Fuwa Fuwa Panic, Sailor Moon Sailor Stars: Fuwa Fuwa Panic 2 and Sailor Moon SuperS: Zenin Sanka!! Shuyaku Soudatsusen.
Super Sailor Mercury plays her water harp and fires an arrow wave of water at her target. In the SuperS Playstation video game, the lyre is golden (as it is in the symbol on Mercury's Crystal Power Stick in the anime) and the background temporarily becomes bluish-green when she summons the attack.
The lyre that Super Sailor Mercury plays and the one that appeared at the beginning of the attack are symbols of the Greek god Hermes or the Roman god Mercury.
