Keira

Keira is the main protagonist of An Ime High, An Ime Spinoff, and An Ime: Return To Sender. She was shown to have some strange obsessions, such as pineapple soap and Lucas from Mother 3. She reset the universe after she got her hands on the dragon egg, which made her forget all of her memories. She was a fairly positive character, who often took the role as a leader in the stories, guiding everyone to the end. In An Ime Spinoff however, she was murdered by Rivas fairly shortly in, returning at the end to introduce the character Pat.

Personality
Keira took the main leader role of the leader, which lead to her having high confidence. She had a slight obsessive personality  (not nearly as severe as Mewese's) as seen by her obsession with Lucas and pineapple soap. At some points, she can be quite hyper and energetic. In An Ime: Attack Of Stuart Little, she went insane after getting locked in Splash Mountain for several days. She's a quick thinker, often thinking of a plan right off the spot. These plans often backfire though, making her seem reckless.

Physical Appearance
In her simplified art style appearance, Keira has white skin and long, light blonde hair. In later drawings of her, she has a top hat on her head, besides from that she looks about the same. In some drawings, she has glasses on, but in others she does not. This is a strange reoccurance throughout the series.

In An Ime: Return To Sender, she appears as a Stardew Valley version of herself, being slightly stretched across the X axis. This same picture was used in Lost An Ime.

An Ime High
Keira takes the role of the main protagonist, and most of the story is told through her perspective.

An Ime Spinoff
Keira assumes the role of the protagonist again, but was quickly killed off by Rivas, who takes her place as the protagonist. She later returns as a supporting character.

An Ime: Return To Sender
Keira again takes the role as the protagonist, the majority of the story being from her perspective.

Lost An Ime
Keira again takes the role as the protagonist, this time the whole story being told from her perspective.

An Ime: Attack Of Stuart Little
Keira is the supposed protagonist, however, it's hard to tell if she actually is or not, given that each character gets a chapter to themselves. She is later killed off near the end of the book, along with Kalen.

Trivia
