The resulting two volumes of Trinität document Debus’ efforts while also reflecting on his journeys and why his attempts to convince the Japanese about his doctrine failed. For the book’s design, Takahashi adopted the concepts of duality and abstraction, as seen in the exclusive use of black and white and the minimalist symbols donning the covers of each volume. In Japan, when a book is published in two volumes, these are called Joh (upper part) and Ge (lower part); the idea of upper and lower is also part of Takahashi’s design, since the cover of each book is divided into an upper and lower half so when the two volumes are stacked they create one complementing unity.
