Oooh beans per day could work! And he could even stock them up so in case he ever needs a bunch, GIANT STOCKPILE OF BEANS. Perhaps even able to give a few to others for their own use? On a much smaller/limited scale to help keep balance.

But the real question is—would any of them be edible?

(Yesssss goood FELLOW WARRIORS UNITE! Rokurou will definitely be happy to pal around with him and marvel at the beans.)
