Dark side of Irotsuki
Even seems to harmless dreamer, artist Irotsuki have a dark side, but this evil personality hidden among chasers, and this chaser is True Failed Maker, you see there is two Failed Makers, BUT even if they looks same shades of colors is different and one of them don't have eyes and have something like a bloody stain or spot on a face, and this is True Failed Maker aka Senshoku, but in compare of her failed clones Senshoku not attacking Iro-chan personally, she tried ruin dream of her original, judging by her actions, how she actually killing some dream monster like NPCs, she can reflect hidden disgust of Iro-chan to her arts, that meaning Irotsuki been so uncertain i her own art skills so these negative feelings flowed in that special chaser, also since one of chasers is copy of Iro' lil sister but in negative, that meaning Senshoku and her failed clones is bad drawn copies of Iro, her other selves.
