Da Capo II was Circus' twenty-ninth game, but was the eleventh game developed by the development group Circus Northern who had also produced their second title suika and their fourth title da capo . The game's production was headed by Tororo, president of Circus, who also worked on the game's music with Comet Nekono who worked on the game's background . The scenario in the game was divided between five people who worked on the different stories for the heroines who include Kōta Takeuchi who mainly worked on Minatsu's and Anzu's stories, the director of the project Chihare Ameno who wrote most of Otome's and Yume's scenarios, Mochizuki JET who wrote Nanaka's and Koko's stories, Nonoka Maihama as a scenario assistant, and Mori no Me. Initial character design was mainly created by Natsuki Tanihara, but GotoP designed Sakura's pet dog Harimao. Using Tanihara's designs, five more artists in addition to Tanihara illustrated the characters and settings used in the game; these artists include Mochi Chinochi, Mitsumamu, Yuka Kayura, Eko, and Meikai. Tanihara designed Yume, Minatsu, and Sakura; Chinochi designed Nanaka, Koko, and the supporting cast; Mitsumamu designed Anzu; and Kayura designed Otome.
