Aki Adagaki (安達垣 愛姫 Adagaki Aki) is the main female protagonist of the manga series, Masamune-kun no Revenge, and also the goal of Masamune's plan.
She has been made an enemy of several boys, including Masamune Makabe. Currently, in the anime, Aki is engaged to Kanetsugu Gasou posed as Masamune. She doesn't even know that Kanetsugu is actually a woman in disguise that doesn't show romantic feelings towards her and that she's only after Adagaki's family money. In the manga, she ended up accepting Masamune Makabe's confession. Officially becoming his girlfriend.
Aki is a beautiful girl with long black (for manga) / blue (for anime) hair, which is always in two messy low pigtails. She has a fringe just above her blue eyes. She is fair and slim, even though she has a habit of eating more than an ordinary person.
At school, she wears a uniform consisting of a white long sleeve coat buttoned at the lower part, a pink shirt with white linings underneath, and a blue bow with yellow stripes. She also wears a checkered peach skirt, black pantyhose/socks, and brown shoes.
After chapter 48 of the manga. She cut her hair to shoulder length.
Aki is known to have a cruel personality, rejecting boys in humiliating ways-- often in front of the whole school. She hurts others to avoid hurting herself. She hates boys and tends to scare them off. Hence she earned the nickname, "The Brutal Princess" or "The Cruel Princess".
She has no background knowledge on what is considered as "normal" outside, as shown when she wore cosplay clothing to her first date with Masamune Makabe. She relies mostly on her maid, Yoshino, as she is incapable of a lot of things.
She is also self-aware and embarrassed about her eating habits, partly due to hypoglycemia, but mainly because of the disappearance of Masamune, in which she told him that she gorged it off on food and felt miserable ever since. Since she is called the Cruel Princess, if anything embarrassing was to come out of the school that revolves around her (such as her habit of eating too much) Aki's image of being the cruel princess would be tarnished. This is one of the reasons why she eats in the storage room, another is that if she was eating a normal amount of lunch, her stomach would rumble loudly afterward which can distract her classmates and would embarrass her at the same time.
Meeting 'Piggy'EditEight years ago, Aki was treated like a princess in the Adagaki Castle. The head maid, Yoshino's mother, had scolded Aki for braiding the mop. Her excuse was that she "grew bored ever since Yoshino wasn't around when she came down with chicken pox".
While Aki's parents were bickering, which annoyed her, she spent time with her dogs, Sean and Lancelot. Her pets picked up intruders, which were incidentally Masamune and his bullies. Despising the likes of bullies, she scared off the bullies with Sean and Lancelot, saving Masamune, which he was grateful for.
Aki's parents fought over her, wanting her for themselves. They did not consider going out as a family. Much to her dismay and due to the result of this, Aki found it much more pleasing being around Masamune. The "King" and "Queen" had often bought her presents, most likely to compete for her affections.
Being around Masamune, who would have often come to her garden, made her wish that her parents had the same honesty as he did. It was when he started crying that she decided to make him stronger. Being around him raised Aki's emotional state as they grew closer. They even took a picture (the only picture).
After helping accomplish the revenge of Masamune's bullies, she confessed about her parents getting divorced and Masamune comforted her, vowing to always be by her side. Through the fun days they shared, she had grown to love him and when he never showed up, Aki turned to overreact.
The Arrival of MasamuneEdit
Aki's first encounter with Masamune's evolved appearance was when she came to his classroom to reject and embarrass yet another student, giving him the cruel nickname, "Prince of Stooges" (or "Pudding Prince" in the anime). She then had not realized or seen the resemblance between Masamune's former 'Piggy' self to his present self.
Throughout the remainder of the day, she didn't notice Masamune spying on her. When he trips into the place where she secretly eats her bentos, she was shocked but angry in the meantime. He was lucky to have escaped alive.
Later Aki confronts the boy she recently rejected, Tanabe Akio, who tries to snip her hair for giving him the nickname Prince of Stooges as a reply for his confession. Masamune interferes as Tanabe jabs the scissors, resulting in a hand injury.
Masamune tells Aki that he knew something like this would happen. When he asked her whether she was hurt, she answered that he was the one hurt. In reply, Masamune says: "Your safety is more important," rendering Aki speechless. Masamune hides the pain even though he felt like going unconscious due to it.
