Makiko Oriotorai (オリオトライ・真喜子, Oriotorai Makiko) Class 3-Plum’s homeroom teacher. Self-centered in both speech and action, but is a very personable teacher who always thinks of her students. Has incredible physical power, to the point where she is called a “Real Amazon”. Loves alcohol.
As revealed in Volume 10-C, she was Toori Aoi's daughter created from the combined DNAs of Toori and Horizon Ariadust.
Makiko is a young woman with brown hair and eyes; she has short hair except for a thin lock of hair which extends to her back, tied in a ponytail. Her uniform resembles a stereotypical physical education teacher's outfit, with a loose dark blue long-sleeved shirt worn over a white undershirt, dark blue jogging pants and running shoes. Her sword hangs on her back.
She is always energetic and shows a wide grin on her face most of the time. Her style of teaching is somewhat unorthodox, involving her students on personal fights under the excuse of showing a practical lesson and not showing mercy to her students on activities. Heidi once revealed that Makiko is a sort of a delinquent, finding herself in trouble most of the time and getting scolded by her superiors as a result.
In spite of her unusual way of teaching, she is able to commend her students for displaying certain traits on battle, including not leaving fallen allies behind.
Little is known about Makiko's past. She reveals that she knows that the Aoi family has worked for the Ariadust (or Matsudaira) family as guards, and she also knows about the Nikyou Crest that is seen on the spot where people are spirited away. According to her, there is a part of her resumé that is "unknown to many".
Makiko is an expert in handling a sword and is a highly agile and cunning fighter, displaying resourcefulness and quick reflexes on tight situations. She is able to use her sword and its sheath in a multitude of ways while in fights, and can hold off multiple attacks at once. Makiko has also demonstrated that she can hold off her entire class by herself without being touched.
It is also shown that she can leap several meters off the ground and land without injury, although it is unknown if there are other factors involved in this ability.
