Glace's space place case

Davis is now 13 and in the 8th grade. He has made new friends. One day, while visiting his new friend Mameme, he gets run over by a 15 year old alien girl named Glace while riding on her motor bike. She hits him on his head with her guitar which causes machines to come out of his head. She then moves into his home and his life turns supernatural again, due to Glace and her guitar.
