Monsterpedia Entry
''“A Chimeric Monster created by Promestein. A fusion of monster and an angel, the primary focus her creation was on the use of mechanical organs. Although she was beneficial in improving the basic technology, she wasn’t particularly powerful. Due to that, she was assigned to the invasion force for a small country town.''

''Due to her multiple mechanical organs, she is able to squeeze multiple prey dry very quickly. This technique of being able to process multiple men at once was put to use in later creations as well.”''
