The third volume was also a pretty good read. Haru definitely feels different from anybody else we've met in the setting. As much as people have joked about her resembling Yuu, physically, They are extremely different. If I was going to compare her to anyone, I'd probably put her more in line with Akari or Natsuki. I laughed my ass off the first time she invited Sayaka over and started broadcasting her sexual preferences. "Here, Senpai, Take this rainbow colored glass. Look at it. See the pretty rainbow? Note how it's rainbow colored please. I'M GAY OKAY" I also appreciated Sayaka's sharp grandma. She knew what was up well before Sayaka did, and it was very amusing. i was hoping we'd get a coming out scene at some point, just so that Grandma could just respond with "Oh, dearie. We know. We've always known."
Ultimately it was very gratifying to finally see Sayaka find happiness, and after two volumes of watching her pursue dead-end relationships, seeing her being pursued for once was nice. The unexpected appearance of swimming-pool girl in the last volume was also a fun moment. I felt bad for her when Sayaka bolts in V1 so it was nice to see that it was still a positive memory for her.
In my opinion the light novels should be required reading for anyone who’s read the manga. It was so immensely cathartic to see Sayaka’s arc completed throughout the trilogy, and for her to finally get that happy end she so desperately deserves.
Also I totally ship Manaka and Midori, if I had more motivation I’d write a fanfic about them.
