Ik most of my followers won’t know who Caine or Hatsune Miku is but I’m posting this anyways cause I can post whatever I want Think about it.. Caine and Hatsune Miku are both robots / ais, and, since Hatsune Miku has no canon design and all designs of her are canon, Hatsune Miku could technically take the form of Caine . Also, in the song by Bunnycat named ‘All I Am’, Caine is sung by Hatsune Miku, meaning that could be one of Hatsune Mikus designs, meaning HATSUNE MIKU IS CAINE GUYS TRUST!!!!
I made this theory with the help of one of my friends, @ flowermeluv :)
