Prior to "Kantai Collection", the majority of games published by DMM.com were R-18+ adult online games. In an effort to attract customers from a wider audience, DMM.com experimented with "Kantai Collection" in partnership with Kadokawa Games; by November 2013, "Kantai Collection" accounted for 30-40% of DMM.com's total online game business.
