In 'Whose Hello?', players step into the shoes of a quirky private detective named Ivy H. O'Rations, who has the unique ability to see the emotional states of people in the form of colorful auras. Set in a surreal city where everyone speaks in riddles and metaphors, Ivy receives a bizarre case: someone has been sending sinister greetings that unsettle the locals. As players navigate through a web of absurd characters, they must interrogate suspects, solve emotional puzzles, and decipher bizarre clues to uncover the identity of the 'Hellos' culprit—all while maintaining their own sanity and sense of humor in a world that seems a bit too off-kilter.
