This is my thoughts on the route before reading Refrain. My opinion is subject to change.
Tonokawa seems to really like classic Key games for some reason. I mean, the initial ending really reminded me of the concepts introduced in both Kanon and CLANNAD, with a focus on dreams, wishes, and memories. The feels half of this story is so bizarre and full of these tropes, it isn’t even funny. Still, the execution of this is good, and I did enjoy much of this route, despite my qualms about it.
Kurugaya herself is a decent character, but what I did not understand is why she talks so profanely and yet has no clue what it means to love. You’d think that she’d have at least had one romantic relationship before meeting Riki, but I suppose that’s something that threw me for a surprise with this story. I expected Kurugaya to be such an expert about love out of experience, but her ‘knowledge’ is from books instead, and she’s never had the chance to experience love for herself. She reminds me a lot of myself in this respect, so I can sympathize with her in some way.
Up until the second half of her route, I consider this route to be the most ‘Little Busters!’-esque out of them all so far. This wasn’t just about Riki and Kurugaya, it was about the whole team working together to bring these two individuals closer. I enjoyed this part of the route immensely, and it really stood out to me over the other routes, but the problem here is the outcome. The ending is a hopeful one, but it isn’t necessarily happy, unlike the other good endings.
So, in the end, Kurugaya stands as one of the weaker routes of Little Busters! to me, but with Refrain soon on the horizon, time will tell if my opinion will change…
