When you talk about galge, you can’t not bring up eroge, and when you talk about eroge, you can’t not think of the ones that left a real impression, and when you talk about leaving an impression, you can’t not think of Kami no Ue no Mahou Tsukai, and then you can’t not bring up the writer behind it: Rukuru. And when you talk about Rukuru, you have to talk about his new game with Kiriha at the end of 2018, Sora ni Kizanda Parallelogram. Going from literary subject matter to a sports backdrop—truly a double bloom, literature and sport both, worth keeping an eye on. I’ve brought up Rukuru more than once, and I’ve recommended the stuff he wrote more than once too. The biggest factor is just how good his stories are. Rukuru can tell a story, and his prose isn’t childish either—it reads comfortably, and that’s his biggest charm and personality. Sure, some people rag on him for all the typos, but who among us who writes every day doesn’t have a few typos (I’m not talking about myself here). So the release of Sora ni Kizanda Parallelogram put me in a bind. The dilemma is pretty obvious. On one hand I was looking forward to a new Rukuru game and that familiar sour-sweet script of his. On the other hand… this new game… Sora ni Kizanda Parallelogram… doesn’t it feel a little too bootleg? You don’t need me to say it—anyone with eyes can see it. This so-called Sora ni Kizanda Parallelogram, whether you look at the setting or the character designs, looks extremely similar to a certain work from a certain studio that’s already dead. Yeah, that’s right—Sprite’s Aokana: Four Rhythms Across the Blue, aka Aokana. Same airborne sport, same male lead as coach, same four hair colors for the heroines. Opinions on the game were all over the place at the time; most people figured it was Aokana’s “spiritual successor,” since the setup is just too similar. At the same time, people were guessing based on Rukuru’s previous style—would Sora ni Kizanda Parallelogram have people dying left and right, getting crippled, all that mess…? After all, his previous games were all gloom-and-doom. So I was worried. So I was torn. But whatever the game turned out to be, you only know once you’ve cleared it. As 2018 came to a close, before the Sino-American co-produced Journey to the West started filming, I finally finished this one. And I ended up even more confused. “Compared to his previous work, is this game a step forward or a step back?” Maybe going back over the whole game will make the answer easier to reach.
