Kara no Kyoukai: Mirai Fukuin - Extra Chorus

Mikiya Kokutou gives Shiki Ryougi a cat to watch, as he will be away for a little while. Though Shiki protests, he leaves the cat anyway, and Shiki is stuck trying to understand her new feline companion. But as luck would have it, the cat seems to have taken a liking to Mikiya and misses him. Later in another part of the city, Ririsu Miyazuki visits the place where her dear friend committed suicide.
