O-Man is an NPC that can be found in the The Mall.

Overview

O-Man's head resembles a purple "O" or theta symbol with a single red eye in the center, alongside a skinny, pink body with two legs and light purple shoes. He produces a blue quarter note and a pink eighth note from his head as he makes music. He is visually similar to E-Man in the reception room one room over from O-Man.

O-Man can be found sitting on a sofa chair in a room with a strange framed picture on the wall. Next to O-Man is a flute lying on the floor which gives the Flute effect when interacted with for the first time. O-Man simply sits on his sofa and produces chiptune music, which stands out from the other music tracks associated with the surrounding area.

Flute Room BGM

When Madotsuki uses the Cat effect, he will appear to be angry or uncomfortable, bobbing his head and changing his expression while the effect is used. The player can also stop his music by using the Stoplight effect, which will make the room silent. Madotsuki can kill him by using the Knife effect, thus allowing her to sit on his sofa, though this also stops the room's music entirely.

Trivia

A parallax background bearing the likeness of the two characters.

• The parallax background in the Graffiti World somewhat resembles O-Man and E-Man, indicating a recurring appearance of the characters. It should also be noted that Graffiti World and the Mall are connected to each other through the top floor's elevator.

Theories

Some have interpreted O-Man to represent a doctor or therapist of some kind. O-Man is located in the Mall, though said location bears some resemblance to a hospital, as several posters resembling body parts, a reception desk, and a sneezing E-Man can all be found there. Going past the reception desk leads to O-Man. It is also reasonable to assume that Madotsuki would see a therapist or doctor considering various unnerving or harmful themes seen throughout her dreams, such as violence or traffic accidents, which have led to many other theories.

O-Man's production of music and close proximity to the Flute effect may also tie into music therapy and the doctor/therapist connection detailed above. The Flute being located in the same room may also be interpreted as the flute being given to Madotsuki by O-Man himself in order to play alongside him. In YUMENIKKI –DREAM DIARY–, O-Man is also given a more humanoid appearance (while wearing a coat closely resembling that of a doctor's) in which they physically give Madotsuki the Flute effect by handing it to her. Another peaceful NPC that may tie into the theme of music therapy is Seccom Masada-sensei, who owns an organ that Madotsuki can play.

It should also be noted that the chiptune music O-Man produces is very similar to the style of music heard in the FC Worlds, which appear to be a result of Madotsuki playing NASU. It's likely O-Man is another example of a real-world object in Madotsuki's room affecting her dreams, as NASU is the only source of music there.
