Calcium is not only Miku, he just has a Calcium that looks like Miku. Rakune(?) And its fan-art people. It doesn't always have to be "Cute little Miku" this is a work of art, your opinion is yours keep it to yourself.
You fail to see meaning behind pieces of art. Based on Bacterial Contamination, Calne Ca is a monster Miku (or "Calcium") imagines herself as after being infected by the virus known as bullying. Calne Ca is a "monster" created to symbolize pain and suffering by showing that she's only darkly colored and not completely made.
Why are you so obsessed with this Deino guy? Can you leave him alone or something? Accept the fact that people can interpret one thing in a darker sense? deviantART doesn't have a time-out corner I can send you to...
This isn't the first guy I've seen slamming deino's work, honestly the only thing we could do is submit a abuse report for harassment. He even has 'anti illuminati' thing on his page that has deino's work in it as examples. IDK. It's stupid.
People need to grow up. I enjoy Deino's work greatly.
