A spin-off manga of DaCapo II written and produced by Circus staff with Shirakawa Nanaka as the main heroine? COUNT ME IN!!!
This is “Da Capo II Imaginary Future”, and just as the title implies, it’s an imaginary story line. As of now, there are three volumes. I heard that in this version Nanaka is the littler sister of Yoshiyuki rather than Otome and Yume! And if it follows Da Capo tradition, the lead will end up with his sister! NANAKA FANS REJOICE! ^_^
Only the prelude chapter has been released, but I’m already interested in the premise alone and will enthusiastically wait for the next ones.
Open Your Mind 
Oh noes, on one hand, this could be a REALLY GOOD THING for the Shirakawa line… On the other hand, it’s more Da Capo… -_-“
