But is it really the Earth they know? Goodbye volcano high x Halo crossover

It is first thing that i write that is not homework, and it's writen by person with iq at the Antarctic temperature level, who's native launguage is not English so don't mind grammar errors and try to ignore them (just comment where do i made a mistake and i'll try to fix that)
it is 'Goodbye Volcano High' and Halo crossover first chapter will be soon but next will be after game relase because demo and trailers do not shows much story but enough to begin
