Kitaru Harekake no Ashita yo
来たる晴れかけの明日よ · きたる はれかけ の あす よ
est. Rough estimate based on volume count, reprints and magazine — not an official figure
Overview
Harehito and Oujirou are trash collectors. Harehito's hands can fix anything, like magic. When Oujirou's heart is broken, Harehito's hand, warm on his back, brings him to life. Once again, a request comes in to pick up a dormant boy. It's another sweltering day. Just like the day Harehito "collected" Oujirou as trash.
