Kaede Kayano

Kaede Kayano (real name, Akari Yukimura) is a student in Class 3-E of Kunugigaoka Junior High School, taught by Korosensei.

Appearance
Kayano is a pretty girl in spite of her short stature. She has a lithe frame, hazel eyes, and green hair which is always fashioned in unique, cat ear-styled pigtails.

Personality
Kayano is one of the more passive members of the class. She frequently acts as support in assassination attempts with her ability to assess the situation and herself. She experiences a severe complex when it comes to sex appeal, usually loudly voicing her discomfort when being around large breasted women. Despite her apparent passive nature, she's very strong willed and extremely devoted to things that interest her.

History
Her full backstory is unknown, but Chapter 128 reveals that she was the student who broke one of Gakuho's personal item, being sent to Class E almost immediately.

Plot
At the first chapter, Kayano was the one who asked the target teacher what name they should refer him as; he tells her that they can decide. After Terasaka's failed assassination attempt, she says the name she thought of for the teacher: Korosensei. In spite of her main character status, she tends to remain on the background, being geared mainly towards logistical support.

She gets the spotlight in Chapter 80, in which she devised an assassination attempt purely based on her love of pudding. Although the attempt was unsuccessful, her classmates were impressed on how straightforward and well thought out the plan was.

During the following arcs, she remains occupied on logistical and supportive roles, being Team A's only non combat member during the God of Death incident, and helping the class during the School Festival and the Play.

In Chapter 128, she returns to the spotlight. Along with Nagisa, she's tasked with storing away the props from the play Class E had recently made, with Korosensei quickly offering to help them. In the shack, after reminiscing her time spent with the class, she reveals she possesses two black tentacles sprouting from the nape of her neck. She suddenly attacks Korosensei, stunning him. She promptly states her love for him, along with her desire to kill him.

Nagisa Shiota
Kaede and Nagisa are regularly seen together and appear to be good friends. It has been implied that Kaede may have feelings for him which is later proven to be false. During the Assassination Test of Courage, Korosensei paired Nagisa with Kaede. In chapter 128, it's revealed that her reason for being around Nagisa is to merely disguise her massive bloodlust.

Karma Akabane
Oddly enough, she was unaware of Karma's reputation for violence when he joined Class E, and thus was slightly wary of him at first. However as time went on they are shown to have a friendly relationship, as they are seen together regularly.

Korosensei
Korosensei is her target. Like most of the Class E students, she quickly warmed up to him. She was the one who gave him his current name, something he was truly grateful for. In Chapter 80, it was revealed they share the same passion for sweets, prompting her to devise her own assassination attempt, which was based completely on their mutual interest in pudding. In Chapter 128, it's revealed that she is in love with him.
