"Eien Densetsu" by Jesus Drug/Mirai Jukan. I know this has at least one Galaxia picture, it's based on the Sera Myu by the same name.
"Stars with Love" Has a lot of really cute scenes, including one that has Seiren and crow. At the end it has a parody retelling of the Bar Scene of the manga with Galaxia. I have a CD with this one on it.
"AURORA" by Yoshida Osamu and Fuuren. Again I know there is at least one Galaxia picture in here.
"SAMANTHA" by Roudohkuimai. Some of the images are very odd in here.
"ECCENTRIC PLANETS" by the circle Fuan Fare.
"Love Wing" by Hello World. Great artwork, only one Galaxia picture,
but still I love it. I own this one.
