Dorothy Fahn (as Midge Mayes)
Machiko's usual attire consists of a grey jacket with gray pants and a white button-up shirt.
Her swimwear is a two-piece with a red swimsuit top and a black bikini swimsuit bottom. This has appeared in episodes 4, 7, and the Special episode Kamogawa Pool Cleaning. This is often accompanied by a blue and white jacket.
At one point, she has worn Kamogawa's school swimsuit in Special episode 5, Kamogawa Love Story, much to the confusion of Shōko Igarashi.
Machiko is considerably strict and tough on several people, particularly on Madoka Kyouno. However, this is mostly so Madoka can figure out problems by herself.
- Machiko's surname Iwabuchi means "rock" (岩) (iwa) and "abyss, edge, deep pool, the depths" (淵) (fuchi/buchi).
