Heart for a Torso of Sorrow

Scarlet, a first-year student at the University of Fine Arts, is more sensitive than anyone. Due to its nature, I couldn't get used to it well, so I drew "pictures" as a place to escape lonely feelings. One day, Hiiro decides to do a part-time job at an art museum with Isshiki of a classmate. When the part-time job was over and they were about to return, they found an unnaturally placed black painting. When I stretched out my hand while feeling awkward, I was swallowed by the painting so much-!? Mysterious painting fantasy opening!
