This is the Japanese version of the ending credits theme. The Japanese zombie vocals were performed by my Dad, and I'm singing the sunflower's part. We thought it would be funny to have him immitate an overzealous Japanese gameshow host rather than use the expected zombie sound (if you understand Japanese and the style of grammar he is using, it is hilarious hearing that type of voice mixed with it).
I have listened to this album probably like a million times now. It's my go-to music for when I'm working. The compositions are lovely and they remind me of how much I love Fleuret Blanc's story. Laura Shigihara
