Wakusei Koukitai Little Cats (1997)

Little Cats is somewhat similar to Sakura Taisen games, with adventure and dating elements reduced, and simulation elements added. David has to make schedules for the girls and decide how much and what exactly they should train. Running competitions, shooting range, robot navigation - everything can be trained, but at the expense of the girls' stamina, which means they will need to rest as well. During the simulation mode, it is also possible to wander around the space station and spend time with the girls.
