Oh no! No. 6 x Tokyo Ghoul I thought the same thing when I saw it!! they even have the main protagonist's hair turn white in both!
Nezumi x Shion (No.6) aaaaaawwwwwwwwwwwwwwwwww <3
I don't like the gender-bending, but I do think this is good artwork to learn from for my own drawings. Good poses and lines.
Shion x Nezumi
