Ink; has lack of emotions, drinks vials for emotions, he makes so many best friends, lovable goof, has bad memory, his pupils can change shape, size, and color, he was a magical ink brush, he is the Au protector, he is friends (enemies) with error, says weird things like ‘water hungry’ or something weird and doesn’t make sense, does dangerous stuff but never brings people who don’t like it, enthusiastic, silly, writes stuff on his scarf sometimes
