Plot
Manami was one of the first characters to be formally introduced. She was properly introduced in Chapter 7 when she flat-out asked Korosensei to drink her poisons. The first poison was revealed to be sodium hydroxide which caused Korosensei to grow horns. The second one was thallium acetate which caused wings to grow at the back of his head. The third one was aqua regia which turned him back to normal, but instead of his usual smile, he had a poker face that resembled an emoticon. Korosensei told Okuda that as a teacher he cannot overlook the safety hazards of a student creating her own poisons and then tells her that if she has time after school then they'll make a poison that'll kill him which she excitedly agrees to.

After school while the two are creating poisons, Korosensei notes that Okuda's grades in science are excellent to which she responds that it's the only thing she's good at, putting emphasis on Japanese being her weakest subject. She states that she can't find the right words to express how she feels and that she never knows what is the right answers as opposed to science and math where there is only one right answer and that to her, beautiful words and clever thinking with emotions are unnecessary. After that Korosensei gives her a worksheet for homework. The next day, Okuda has her poison ready and is ready to give it to Korosensei. She gives it to him and after he drinks it he thanks her for the "medicine" that'll allow him to evolve. He later reveals that he had her make a medicine would turn him into a liquid state and while he proceeds to fly throughout the classroom, the other students start shooting at him. When he finally settles into a corner on the ceiling he tells Manami that no matter how good at chemistry she may be, without the necessary language skills it'll all be futile and to continue working on her language skills,

On Chapter 24, she made another debut by making customized BB pellets from magnesium as a main ingredient. She even nicknamed it "Victoria Falls" because of the super laxative BB pellets that she made by herself as Korosensei requested.

Abilities
Poison Making: Despite the fact that she states that she isn't really good with surprise attacks and expressing things in language, Okuda excels in chemistry and mathematics and is very capable of making even the most deadliest of poisons for various situations.

Science: Okuda has a talent with this subject and after learning to incorporate literature into it, she has become even better at it. She's also ranked first in the school for the subject.

Karma Akabane
Karma and Okuda are shown to get along quite well. Karma has openly admitted that he is attracted to her due to her mastery in poison making and Manami, though unaware of this, thinks of him as a good friend. The two were also paired together during Korosensei's Test of Courage.
