I really enjoyed this demo! The leads have really sweet chemistry and I could really tell how comfortable Hikaru feels around Aki ;_;
You do a great job of making things feel very anime in a fun and engaging way without falling too deeply into stale tropes. The spookiness was also executed very well. I definitely felt that near-constant haunting dread from the spooky lady. I also liked the little prologue that provided some insight into Aki's perspective and revealed a few things about him we might only have found out way after the events in the demo otherwise.
I definitely want to see more of these two!
