CAE coolkid

Story: CAE coolkid was originally just a painting, but his creator accidentally used a magic paint brush and didn't expect him to pop out of the painting, now he hunts for all the 7 colours he craves for, he mainly is slightly deranged & doesn't realise he's going around killing everyone, he is only naive, a voice speaks to him to find the final colour he needs, the one of the sun, the yellow hue, sometimes he realises what he's doing for a short moment and he starts to question his true pourpuse before the voices tell him to snap out of it and keep doing what he "has" to do. . Description: 12 yo, 5'11, has a nacklace with 6 hues on it that he has collected with 1 more remaining, has a monochrome sword & can summon minions of him in the hues he's collected.
