Chinese language and history enthusiasts may find some interest in Kongming's use of Chinese proverbial knowledge as well as war tactics to either outwit Eiko's competition or to teach her how to overcome her weaknesses. There's some also (not so) subtle word/naming choices made in this series, like how the Kanji in Eiko Tsukimi's name shares two characters with the wife of Kongming in actual history. I am personally not an expert on these references, but it adds to the charm of the show knowing fine details like that exist.
As a production in general, the animation for characters and backgrounds is fluid and during moments where Eiko and other characters are performing, the animation in most cases faithfully follows what they're singing/playing on guitar. The backgrounds were not neglected either, as the city of Shibuya is captured beautifully in multiple lightings with a lot of detail to spare. Even more impressive is how various youtube singers voice the songs performed by the characters in this show. Most notably 96neko as Eiko's singing voice, made even more impressive that the song "Be Crazy For Me" is mostly ladled with English lyrics that are delivered with impeccable, while definitely Japanese-accented pronunciation. With all that considered, it's no wonder Eiko's voice captivated Kongming, leading him to work towards her victory. The music is very well done and a true highlight of the series.
Perhaps the only remote complaint I could scrounge up about Paripi Koumei is that it's not a non-stop action series, and flows more akin to a slice of life. Maybe an episode or two is slow paced inevitably because in many ways it's a story about everyday people dealing with personal insecurities while they dream about higher achievements. It's a relatable experience with a twist of fantasy, but the show is certainly quite exciting when Kongming demonstrates that his wartime cunning can be applied to bring victory without ruin or bloodshed, in the form of music that makes everyone happy. Truly this show made me happy as well, between the story, wit, and production values. I think there's something for everyone to appreciate in this masterpiece.
