Akuru Akutsu (阿久津 明 Akutsu Akuru) is the deuteragonist in Aho-Girl.
Akuru is a handsome young man with short, straight, black hair, bangs, fair skin, and hair framing his face. He has stern-looking brown eyes, and a serious expression. He usually wears his school uniform.
Akuru is an intelligent and serious high school student who is forced to deal with Yoshiko Hanabatake’s stupidity. Though only interested in studying, he is unwittingly dragged into many of Yoshiko’s escapades much to his dismay.
Throughout the series, Akuru is seen as the straight man, constantly dealing with the eccentric personalities of those around him (especially Yoshiko) and is quick to make rude remarks. He is very upfront about his disgust for Yoshiko, often resorting to physical violence whenever she annoys him.
Despite this, Akuru is said to be strange himself as he is completely antisocial, having few friends due to his abrasive attitude. The only people Akuru gets along with is Sayaka Sumino and Dog who are the only beings besides him to have sense.
Akuru has known Yoshiko ever since he was 5. He is annoyed by her idiotic personally and wishes she would leave him alone. They're neighbors and their rooms are right across each other. Yoshiko considers him a best friend and lover but Akuru considers her a pain and a drag down. Yet, they still hang out and walk home together.
Akuru often scolds Yoshiko, due to her eccentric and stupid personality. They're good friends since childhood. He cares about her but doesn't really show it. He was the one that first introduced her to bananas (her absolute favorite food) and hits her a lot. A good example is when he punched her high in the air after she showed him her panties. They are polar opposites.
The only person he considered as a friend. Sayaka befriends him out of pity after knowing he doesn't have friends, to his dismay. They get along well with Sayaka being the only person that he doesn't mind or yell at. He considers her "normal."
Ever since she fell in love with Akkun, she has started deviating from the right path without realizing it. She is also part of the Disciplinary Committee.
Ruri is Akuru’s younger sister. Though he does genuinely care for her, Akuru seems to have very low expectations of her and often tells her how it’s okay to be a failure, prompting her to not like him. However, Ruri still loves him and will go to him when she sees he is in danger.
Ryuuichi tries his best to become friends with Akkun, but fails numerous times until chapter 105 when Akkun says that he will consider it if Ryuuichi does what Akkun tells him to. Akuru was shocked to see Ryuuichi was actually smart since he scored higher than him in tests. Akuru doesn't like anyone smarter than him which proves how much of a jerk he is. Akuru did compliment Ryuuichi on his act since he showed he wasn't idiot like Yoshiko.
Akuru is deeply disgusted by Yoshie's pervert personality and hates her betrothal plans of him and Yoshiko. Akuru sees that Yoshiko gets her eccentric attitude from her mother since the latter's father was normal decent man.
Akuru initially did not like The dog but it grew on him since the animal was behaved and understood him. Dog seems to be the only other being besides Sayaka that Akuru likes or isn't irritated by, as said dog seems to be more intelligent than Yoshiko.
She has a crush on him, mainly because of Yoshiko's stupidity to make her look like she doesn't know what "love" is.
