It was the 10th anniversary of "Neko's Kawaii!" and the 1st anniversary of "Kimi wa Ne." This is the conclusion of "Neko's Kawaii!" that was conceived in 2016. "Neko's Kawaii! ~Crane Animal Hospital in Operation~" - Aftermath of "What a Wonderful World" ↑ - Aftermath 2 following "Souvenir" "Kimi wa Ne Couples" I think most of this won't make much sense unless you've studied the above works fairly thoroughly. Since I've only included the bare essentials. Especially "What a Wonderful World" - it's very much for enthusiasts, as it's desirable to view several versions scattered across the internet and so on. I've included a brief explanation in the afterword.
