Sailor Moon's Moon Spiral Heart Attack
Megumi Urawa (original anime)
She was created from a volleyball, and can use an energy volleyball as her attack. She can also trap people in a volleyball net.
Kaorinite sent Haikyun after an athlete named Tsutomu Asai. She extracted his Pure Heart, and used it as a volleyball, but Sailor Venus took it back using her volleyball skills, and Sailor Moon destroyed Haikyun with Moon Spiral Heart Attack.
- Haikyun appears in the video game Sailor Moon S: Quiz Taiketsu! Sailor Power Ketsushuu. She is among the monsters that are revived by Quiz.
- She is one of the few Daimons that does not say "Lovely" when she is killed by Sailor Moon's attack.
