Quotes
''“Since the original me died, i've ofter asked myself what exactly is my existence? For what purpose do i exist? Though now there's not much joy in existing as the spark that start World War III, is that my only reason for being? But if it's within my power to save the original Kurisu.... if it's to save this beautiful world don't you think that's more logical and even romantic?”''
