Healing Leaf is a subunit of I've Sound formed in 2002 specializing in duets featuring vocalists Eiko Shimamiya (島みやえい子) and Mami Kawada (川田まみ). They have made only a few songs together (秋風に君を想ふ, 雨に歌う譚詩曲, Slow Step) but each have been featured in PC video games in Japan. The group has been on permanent hiatus since Shimamiya's departure from I've Sound in 2011.
