Unlike Corti, Yardio is more blatant in showing his affection for his contractor. He also likes to fight, and his power level is greater than most four winged spirits. He is a laid back character in contrast to the more serious Eufinley. On the day they meet, Yardio quickly tried to make a covenant by kissing her, but received a punch to the face instead. Yardio Voda Munagoul ( ヤーディオ・ウォダ・ムナグール, Yādio Voda Munagūru) Voiced by: Nobuyuki Hiyama (anime)Eufinley's covenant spirit. In the Shinkyoku Sōkai Polyphonica Crimson S she is contracted to a 4-winged wolf spirit named Wolfis and plays a major part in fighting against the enemy. She has a contract with two spirits, Yardio and Mashat, the latter of whom is seldom seen. She plays a violin-like instrument and is very strict. Eufinley Tsuge ( ツゲ・ユフィンリー, Tsuge Yufinrī) Voiced by: Ayako Kawasumi (anime) Voiced by: Keiko Suzuki (game)The boss of the Tsuge Divine Music Player Office. She was contracted with Kuchiba Kaoru in the past. Corti has a somewhat tsundere attitude regarding Phoron, but this can be thought of more as her not suffering fools gladly, since she actively competes with Perse for Phoron's affections and, in the anime, was shown to initiate closer contact (holding hands) with him.Most of the time, Corti appears as a child, but when Phoron plays his Commandia she matures into an adult figure.

In Shinkyoku Soukai Polyphonica Crimson S, she has eight wings and is called 'Crimson Queen'. She was entranced by the young Phoron's singing voice and thus decided to make a pact with him so he would be hers and hers only. Corti, as Phoron calls her, is one of the eldest spirits in their world, having six wings, and is known as the Red Elder Spirit - as well as other titles including Crimson Annihilator or Bloody Duchess. He once said that he plays Commandia for "someone he loves" meaning his contract spirit "Corti." Corticarte Apa Lagranges ( コーティカルテ・アパ・ラグランジェス, Kōtikarute Apa Raguranjesu) Voiced by: Haruka Tomatsu (anime) Voiced by: Riko Hirai (game)The spirit, Phoron made a contract with.

He is very kind, but naive and somewhat dense. He also uses a backpack-sized piano-like One-Man Orchestra on those occasions where he cannot use his motorbike. He plays an organ-like instrument (that is seen in the first season that can transform into a motorbike. Although he is the master of the Red spirit, Corticarte, he doesn't have a full control over her (because Cortica always wants to follow her own will). Phoron is a Dantist working in the Tsuge Divine Music Player Office.
