During the Wish Upon a Star event Idia is less than thrilled to be assigned the role of Stargazer, despite Ortho’s encouragement.
Idia reluctantly accepts Ortho’s offer to assist him so that Idia himself can participate without leaving his room, reflecting that, “For some reason, Ortho gets really jazzed about the Starsending every year.”
Ortho tries his best to get Idia excited about the event but Idia ends up begging to be excused from the obligation to perform in public. Idia makes a bet with Deuce: if Deuce can improve his dancing, collect all his own wishing stars AND those that Idia needs to collect, then he will preform. Deuce fulfills his end of the deal and Idia finally relents.
A change in the weather runs the risk of the event being canceled, leaving Idia to choose between letting the weather forecast put him on “the Good Ending route” and disappointing Ortho, or trying to change the weather to perform a task he never wanted to do in the first place, all to make Ortho happy.
Idia makes his star-sending wish (the same one he makes every year): “for the sequel to Star Rogue to come out!”
Ortho explains that it was a game that they played when they were younger, but the development team disbanded after a sequel was announced. Despite not having a wishing star of his own (as Ortho was not a student at the time), Ortho wishes for Idia’s wish to come true, saying, “He’s the most important person in the world to me.”
Star Rogue comes up in Book 6 as well, with Idia describing it as, “the story of how one man became a hero…the Gaia Dynasty was thought to have been wiped out in the invasion. However! One of their princes was raised in secrecy…he set forth on a journey to bring back his birth parents and restore peace to Gaia!”
We learn that the game’s development team disbanded because they argued too much.
During the Wish Upon a Star event Idia creates Stargazer Gear for Ortho, capable of carrying him into space so that he can take the wishing stars above the clouds. While testing out his new body Ortho runs into Ruggie, who asks, “…is there even a point to doing all this?” Ortho says it is to make Idia’s wish come true.
Ruggie asks why he doesn’t take the opportunity to ask for what he REALLY wants (“How about wishing to be king? Or never having to worry about being hungry?”), but Ortho decides that what he really wants is for Idia to be happy. “I want his wish to come true. I couldn’t ask for anything more.”
After the event it is revealed that “the original dev team has miraculously gotten back together” after they saw the Ortho-created meteor shower, with development on the Star Rogue sequel resuming, and both Ortho and Idia getting their wishes granted.
