The Boule Brothers worked as minions for the Black Moon Clan.
In the anime, Achiral and Chiral are summoned by Esmeraude to attack Negative Points to open the Dark Gate. Chiral is to corrupt Juuban Elementary School, while his brother Achiral is to corrupt Juuban Park. Sailor Moon arrives on the scene and is quickly confronted by Chiral. Achiral joins his twin and is prevented from harming young Chibiusa due to Sailor Mercury's Shabon Spray attack. Achiral creates his diversion by sending the possessed Momoko Momohara after the Sailor Senshi, and Chiral takes the opportunity to disappear and reappear behind Sailor Jupiter, taking her by surprise.
Chibiusa uses her energy to release Momoko from the brothers' control and blasts the brothers. Sailor Moon, Sailor Mars, and Sailor Jupiter run into the schoolyard after Achiral and Chiral, who try to ambush the girls from behind. They are prevented from doing so by Tuxedo Mask. They then attempt to escape by phasing through the ground, but Sailor Jupiter stuns them with her Sparkling Wide Pressure attack long enough for Sailor Moon to destroy them with Moon Princess Halation.
- In some sources, the Boule Brothers are identified as Droids; however, Achiral and Chiral are strikingly different. They more closely resemble members of the Black Moon Clan, with the symbol of the upside-down dark crescent moon on their foreheads. They also did not die like other Droids generally did, but exploded rather than crumbling into particles. Plus all the other Droids attack on their own and are female, while Achiral and Chiral are male and both attack together.
