Half-scrap metal Alchemist!?

Last wednesday, i had gone through tough times for 4 hours of chemistry lecture and I kept thinking of "OMG, i'm so losing grip...NOO!!!" and this happened again for the next day since on the next day the chemistry class will be hold for 3 hours T_T... Neither losing grip nor my cool, i had to strive to kept the momentum... Anyway, as promised before, i have attached "Tripshots ft. Hatsune Miku - Nebula" PV.. the song also comes in 4 variation of remixes and 1 variation of singers. The PV was, OMG that is the best of all the hatsune miku PV!!!
