Designers Yoshiko Tajima and Ansgar Vollmer met and fell in love while students at Koeln International School of Design in Cologne, Germany.

In April 2003, Vollmer came to Japan and began his research at the Institute of Advanced Media Arts and Science in Ogaki, Gifu Prefecture, on a scholarship. In summer 2004, Tajima returned to Japan after finishing her thesis and graduating from KISD.

The couple married during the cherry blossom season in 2005 and eventually opened a graphic design office in Tokyo's Shinjuku Ward. Together, they create works ranging from book covers, application forms and annual reports to Web pages and corporate designs like logos and style guides.
