The hidden costumes in Devil May Cry 2 were produced as part of a collaboration with the Italian retail clothing company Diesel.

"That was because Tanaka-san, the produce, used to work for them. It was a collaboration that made good use of his last job. People on both sides talked at the time and felt that "DMC 2" and Diesel's visual styles would work well together and could be quite appealing to the casual audience. We were asked to design a belt for the collaboration, and I had the privilege of making the buckle. Seeing Dante and Lucia wearing Diesel fashion on-screen was very cool. There's something neat about watching them run through the game's story while wearing those clothes. It reminds me of "RE" in a way. (laughs)"
