For the most part this book is just a straight up sequel to the fourth volume, with the drama club getting together with our heroes to put on a second play featuring the Blue Knight and the Silver Princess. Like the fourth book, there’s a lot of focus on Theia and Harumi, who compare and contrast even more with each other. And like the fourth book, everything gets derailed by Theia’s rival Clan, who’s out for revenge and has a better gun now. Oh yes, and can fly. That said, for about 4/5 of this book there’s not really all that much happening, and it seems to be content to be a Christmas-themed book showing how well everyone gets along now while seeding possible things for future books, such as Ruth pointing out that serving Theia as her Knight would involve Koutarou moving off-planet.

Ruth is on the cover of this volume, so you might expect to see her get a story in Vol. 8. That said, she does get plenty to do here, mostly acting as support for Theia and trying to nudge Koutarou in the right direction, though there is an amusing side plot of her wanting to get stronger so she can defeat the sentai warrior from last book – who was, of course, Shizuka, who feels uncomfortable about all this. That said, neither Ruth or Shizuka are part of the harem (yet), and so the bulk of the development goes to Harumi and Theia. Harumi is still trying to get Koutarou to treat her as less of a sempai and more of a friend – i.e., the way he treats Theia, which she explicitly is jealous of. Theia does not think about Harumi that much, but that’s likely because she’s unaware of the plot twist we all saw coming: Harumi is in some way possessed by or a reincarnation of the Silver Princess from Theia’s past, and as the end of the book makes clear, Koutarou is literally the Blue Knight.

The climax of the book involves the performance of the 2nd play, complete with Yurika as the most pathetic dragon ever (she’s back to being useless here, though smartens up when actual danger arrives, and the fact that she hasn’t realized her feelings for Koutarou yet helps her keep it together more). The play is, as I said above, interrupted by Clan, who remains petty, spiteful, and very easy to dislike. And then comes the climax of the book, which was a big surprise. Not the actual events, those were the least surprising thing ever. No, I was surprised that the book kept going past where I expected it to. Let’s just say there was a really obvious place for a cliffhanger, but the book chose to go a few more pages and actually resolve most of its built-up tension. It actually worked quite well.

I’m enjoying reading each volume of this series as it really puts an effort into showing how each of the characters is slowly maturing and gaining confidence and strength, as well as bonding with each other. Technically it’s a harem comedy, but the harem all get along, and there’s no real rush to confess, mostly as few of them have even admitted their feelings to themselves. It works very well as an ongoing series, doing the #1 thing such series should do: make you want to read more. That said, I’m pretty sure the next volume won’t feature Ruth, as it’s Vol. 7.5, and tells the story of what happened to Koutarou and Clan during the climax of this book. Be careful when searching Amazon to get the right order.
