I have been a fan of key for several years now and seeing a crossover of most of their licenses was really a huge joy for me. The interactions between the characters are crazy, being able to listen again to all the outstanding music of these stories was also incredible and just the fact of being able to relive the chemistry of the characters of Key and their universe makes this anime a true masterclass. I regret that the episodes are a bit short and consequently the lack of lines of some characters. This anime is really not for everyone. What makes kaginado excellent is all the referencesit makes to all the universes of Key. But there are a lot of unique references to VNs and I think it's important to have done the VNs of Kanon, Air, Clannad, Tomoyo After, Little Busters, Rewrite and Planetarian as well as having a minimum knowledge of Key in general to be able to fully enjoy Kaginado. But if all the conditions are gathered, you can be sure to have a great time with Kaginado!
