A close friend from her own world, Io fought at his side for a good portion of the campaign against the Septentriones, and his assistance shortly before the ritual to release the Dragon Stream saved her life. Since then, her crush on him has developed into something more, to the point that when she went crazy from a Zodiac effect, he was her obsession. She's... still trying to make up for that.
Their Dual Persona is unknown.
DAICHI SHIJIMA
THE CHARIOT RANK: ???
Kaito's friend from high school, who was also with the two for most of the Septentrion campaign. A risky maneuver on his part led to the defeat of the first Septentrion, and when the civilian adjuncts and JP's personnel split ideologically, it was he that Io chose to rally behind, at least until Kaito managed to convince them both that the Anguished One's and his own plan was better.
Their Dual Persona is unknown.
YAMATO HOUTSUIN
THE CHARIOT RANK: ???
The Chief of JP's back on their world. This Yamato, however, appears to be from an alternate reality in which "Hiro Kageyama" sided with Ronaldo.
Their Dual Persona is unknown.
FUMI KANNO
THE MAGICIAN RANK: ???
A researcher that used to be with JPs. Io isn't sure about the exact details of the version of their world she's from, but Fumi clearly has some sort of respect for Io regarding the possibility of undergoing further trials to gain powers.
Their Dual Persona is unknown.
MIYAKO HOUTSUIN
JUSTICE RANK: ???
Yamato's possibly identical twin sister. She's not from the same world Io is, or if she is Miyako's existence was never revealed.
Their Dual Persona is unknown.
AL SAIDUQ
THE UNKNOWN RANK: ???
AKA Alcor, or the Anguished One. The soul and guardian of the new world, and dedicated watcher of humanity since time unrecorded.
THE ANGUISHED ONE
THE STAR, REVERSED RANK: ???
An alternate version of Al Saiduq. Admittedly, Io has no idea what's up with him...
Their Dual Persona is unknown.
LUCINA
JUSTICE RANK: 1
A girl from a world very different from Io's, where swords and magic are the order of the day. Io's and Lucina's memories were tangled up, so each is privy to much more of the other's life than would most likely have come up in conversation.
