Lotta Brest

Daughter of Dr. Brest a leading scientist. She has been a close friend of Billy since they were quite young. Not that they039re all that old now... She often tags along with Billy occasionally even resorting to stowing away to achieve this end. You039d think Emely would be able to stop such behavior... She039s terribly fond of her quotlittle sisterquot Myusha. Source: Wikipedia
