Sonoko Ijuuin  

, 伊集院 園子

At Juuban Municipal High School, Sonoko Ijuuin led the softball team and was a devoted fan of the Three Lights Fan Club. As Sailor Leaguer, she had the power to transform into a Phage. In episode 187, Sonoko became envious of Seiya's attention towards Usagi, whom she considered inferior. She challenged him to a bet: if her team won the upcoming school softball game, he would no longer be allowed to associate with Usagi. When the game was delayed due to rain, Sonoko sought out Usagi and intended to hit the ball directly at her. However, when Usagi admitted she might not catch it but still aimed to do her best, Sonoko was impressed by her determination. After Sailor Lead Crow took her Star Seed, Sonoko transformed into a Phage, but Eternal Sailor Moon saved her.
