I also believe "25(Twenty Five) at the Clubroom with Rias-buchou!" takes place after V12.
 * Ddraig fell asleep at the end of V12 and in this story he awakens to complain to Issei and Rias to let him sleep, and not mention breasts.
 * Issei is calling Rias by her first name.
 * Ddraig does not reappear until V14.
