1. Aki & Himeno
The first couple that cannot be overlooked is Aki and Himeno. They are colleagues in the devil hunting team, working together and operating in the mission of collecting the remains of the Gun Devil.
The relationship between Aki and Himeno is recognized as profound. Aki, fueled by hatred for the Gun Devil after his family was killed in a widespread massacre, joined the devil hunting team and was assigned to lead by Himeno. Despite being older and more experienced than Aki, she also suffers the pain of losing her teammates due to the constant dangers of their lives. Therefore, she lets herself go and smokes, believing that this profession will not allow her to live much longer.
In contrast to Himeno's cheerful and outgoing personality, Aki is somewhat cold and stern. However, over the years of working together, he has opened up to Himeno and treated her gently. Himeno is also confirmed to have romantic feelings for Aki and wants to help him escape his hatred so that he can live longer. Unfortunately, Himeno tragically meets danger and dies, causing Aki a great deal of pain.


2. Chainsaw Devil & Makima
When reading Chainsaw Man manga, it's important to differentiate between the Chainsaw Man and the Chainsaw Devil. The Chainsaw Devil, also known as Pochita, the little dog appearing at the beginning of the story, became the heart in Denji's chest and turned him into the Chainsaw Man. Makima brought Denji to the devil hunting team to work and provide him with food and shelter. However, her true goal is only the heart of Denji - or the Chainsaw Devil.
The Chainsaw Devil is also known by a cooler name, the 'hero of hell', as this devil is the strongest with the power to eat the names of other devils and make the ideas of them disappear from human subconsciousness, thereby significantly weakening them, the War Devil being an example. And Makima - the Control Devil - considers herself a fan of the Chainsaw Devil. That's why she has been following the Chainsaw Devil from hell to the human world, ready to do anything just to get Pochita out of Denji's chest.


3. Love Story: Denji & Reze
If you're a fan of cute and fluffy couples, then Denji and Reze will surely melt your heart with their adorableness! We all know our main character Denji has always yearned for love and affection due to his childhood deprivation, right? While he's deeply infatuated with Makima, Denji also has a soft spot for Reze!
Denji and Reze met on a rainy day, and after some conversation, Denji immediately thought that Reze liked him because of her casual and affectionate gestures. They went on dates together at night at school, attended festivals, ate cotton candy, caught goldfish... and watched fireworks together. Denji and Reze even kissed!
However, it's a bit unfortunate for this whirlwind romance because Reze's true identity is a Bomb Devil sent by Russia to steal Denji's heart, or in other words, the Chainsaw Devil. They fought fiercely, and Reze was manipulated by Makima and brought back to the secret devil hunting team.


4. Unlikely Couple: Denji & Asa
Asa is a character who only appeared in the second part of the Chainsaw Man manga, but many believe that she and Denji make a very beautiful and adorable couple if they proceed to a romantic relationship! Despite seeming somewhat pessimistic and always showing disdain for Chainsaw Man, Denji is actually Chainsaw Man in secret, so he feels frustrated that he isn't liked by a girl.
Although it seemed like Denji would reject Asa, when Asa suggested they go on a date, Denji agreed immediately. They had a date at the aquarium and encountered some minor troubles with the Infinite Devil, getting trapped inside it. Denji comforted and encouraged Asa when she was feeling down, and they also had some fun moments trying to find a way out of the aquarium. Then they had another date at Denji's house, although it didn't go as planned because it was interrupted by Nayuta.
In the latest chapters, when Asa was in danger from the Falling Devil, Denji came to rescue her in the form of Chainsaw Man.


5. Dominant Duo: Makima & Denji
Surely, this couple cannot be overlooked, right? If you love couples with a silly guy and a mature woman, then this is a perfect match for you!
Makima found Denji after the first battle when he became the Chainsaw Man. She brought him to the Public Safety Bureau and provided him with clothes, food, work... she even brought him a small family like Aki and Power. However, Makima always looks down on Denji and sees him as a mere dog to command, while Denji adores Makima so much that he is willing to follow all her orders. They even went on dates together!
Although they make a good-looking couple, in the end, Makima only aimed for Denji's heart. Therefore, they had to fight fiercely, resulting in Makima's defeat and Denji devouring her. However, Denji still affirms that he truly loves Makima very much.


6. Courageous Pair: Galgali & Kobeni
Galgali, also known as the Violence Devil, and Kobeni Higashiyama are members of Special Division 4, demon hunters. They first appeared together when Galgali and Kobeni rushed to the hospital to assist Aki Hayakawa in fighting the Bomb Devil. They arrived just in time to kick Reze out of the speeding car while Denji was recovering.
Galgali and Kobeni often go on patrol missions together. When they encounter a demon, Kobeni hides behind a corner while Violence deals with it, then tells her it's safe to come out. Galgali buys her ice cream, which makes Kobeni very happy since she rarely gets to eat ice cream. When both are transported to hell because of Santa Claus's power, Galgali asks her to wear his mask to protect herself. Galgali then fights relentlessly with the demons of hell and dies, while Kobeni is lucky enough to return to the human world and resign from the Public Safety Bureau.
Although they don't have a happily-ever-after, Galgali's protective actions towards Kobeni still leave everyone touched.
