Square Enix’s Manga UP! Global releases the manga chapters in English under the name The Good Deeds of Old Adventurer Kane, and it describes the manga’s story below:

“Meet Kane: a D-rank adventurer with nothing going for him but his kindness. He’s spent the last 20 years getting by with herb-picking requests, but one day, he comes across a super rare item: The Fruit of Revival! Giving it away for not much more than pocket change, little does he know that his life is about to change…”
