Big Red is a decorative character found at the end of The Sewers.
It is seen as a large red head resting on the ground with a huge gaping maw. It does not move or react to any of Madotsuki's effects. Aside from Madotsuki herself, the whole screen is shown in shades of red and black.
Like other decorative characters, it appears suddenly and is very imposing in the way it takes up most of the screen.
When Madotsuki walks into Big Red's mouth, she is abruptly swallowed and transported to the Windmill World. It will swallow her even when her stoplight is red.
