amazon, book depository, etc.
the official title is The Other World's Books Depend on the Bean Counter.
Barnes and Noble also sells it!
I bought mine in here. The manga and the novels. But they are not yet complete. https://blackwells.co.uk/bookshop/search/?keyword=The+other+world+books+depend+on+the+bean+counter
Where can I buy the official manga?
