Chainsaw Man Love Interests Ranked: From Green Flags to Walking Red Flags

If you love Chainsaw Man but find yourself yelling at Denji like he’s a friend making the same bad dating decision for the 50th time… same. The boy is incredible with a chainsaw, terrible with a crush. He gets starry-eyed at the slightest attention, and that combo tends to drag him toward people who either can’t handle him or absolutely will.

Quick basics while we’re here: Chainsaw Man is by creator Tatsuki Fujimoto, lives in the gore/action/urban fantasy zone, and Season 1 is streaming on Crunchyroll.

Below, I ranked nine of Denji’s romantic candidates and complications from 'might actually be good for him' to 'please run.' It’s part compatibility check, part cautionary tale, and packed with those messy details the series loves.

1. 9. Kobeni Higashiyama (Chapter debut: 10)
   Kobeni doesn’t get enough credit. She’s a jittery panic machine, sure, but that’s also her charm: adorable, shy, and unintentionally funny. She radiates protect-her-at-all-costs energy, and calling her toxic would be off base. For someone terrified of devils, she’s absurdly capable. She does have a contract with a devil, but the series hasn’t revealed which one. Fans float possibilities like the Black Cat Devil or Knife Devil, but officially it’s still a mystery.

2. 8. Power (Chapter debut: 4)
   Power is the Blood Fiend who hijacked the body of a dead woman she found in the woods and kept the name. Early on, she can be aggressively annoying, but the longer you spend with her, the clearer it is that she actually cares, especially about Denji. As a friend, she’s a win; as a partner, she’s a chaos grenade. She can weaponize her own blood into spears, shape it mid-fight, and trap opponents. Even as a fiend (so not full devil-strength), she hits harder than most devil hunters.

3. 7. Fumiko Mifune (Chapter debut: 136)
   Calm, confident, and very put-together, Fumiko has that mature vibe Denji desperately needs. She actually respects him as Chainsaw Man without fetishizing or demonizing him, which is rare in this world. As a Public Safety Devil Hunter, she’s frighteningly competent and keeps Denji in line without relying on any contracts. No flashy powers, just nerves of steel and a sharp brain. Translation: not toxic.

4. 6. Asa Mitaka / Yoru (Chapter debut: 98)
   Two tenants, one apartment: Asa is the awkward, insecure student; Yoru is the War Devil squatting in her body with a manipulative streak. Their dynamic with Denji would be combustible. Asa and Denji could actually balance each other in a weird way, while Yoru would absolutely play mind games. If the goal is keeping the Chainsaw Devil side of him calm, Asa might manage it. If the goal is Denji staying emotionally intact… proceed carefully.

5. 5. Himeno (Chapter debut: 10)
   Himeno felt tailor-made for Denji’s brand of chaos: flirty, teasing, and mature enough to steady him. The snag is she was all-in on Aki, which slotted Denji into 'good boy' territory. If she’d actually reciprocated, it might have put a battery in Denji’s worst impulses and pushed him toward being toxic himself. A perfect vibe match on paper, but the emotional availability wasn’t there.

6. 4. Quanxi (Chapter debut: 54)
   Quanxi has 'cool-headed apex predator' energy: eye patch, white hair, and a stare that says you’re already dead. She isn’t cruel to her subordinates, but she does use people, which is not promising relationship material. As the first Devil Hunter out of China, she’s a legend, moving so fast enemies realize they’ve been cut down after she’s finished the next one. Even among hybrids, she’s built different. Incredible to watch. Terrifying to date.

7. 3. Reze (Chapter debut: 40)
   Reze is the textbook 'best girl' who is also a walking red flag. She hid she was the Bomb Devil and betrayed Denji because that was the mission. If not for him, she would have completed it like flipping a switch. Then things got complicated: after her reveal and some brutally honest moments, it felt like she genuinely cared about Denji. She was sent by the Russian military to capture Chainsaw Man, specifically Pochita’s heart, but somewhere along the way, they actually fell for each other. She’s a lingering curse for Denji, sure, but she also taught him how to swim. That’s Chainsaw Man in a nutshell: sweet and catastrophic at the same time.

8. 2. Death Devil (Chapter debut: 108)
   Previously presented under the alias Fami, she kept her true identity as the Death Devil tucked away, which tells you how calculated she is. She gives off the same composed, manipulative aura that made Makima so dangerous: friendly on the surface, something much darker underneath. For Denji, this is a do-not-touch sign. He’s already survived one control-obsessed devil; getting close here would be the sequel no one needs, and probably worse.
   Note: If you’re blinking at the alias situation, you’re not alone. The identity politics of the Horsemen can get confusing fast.

9. 1. Makima (Chapter debut: 1)
   Makima is the blueprint for toxic. Yes, she’s the Control Devil, but even with that context, the way she treated Denji as a literal tool (and a dog) is stomach-turning. Once her full deal came to light, a lot of fans re-evaluated her fast. She’s the most dangerous person Denji ever got attached to, period. The perfect example of 'don’t trust a book by its cover' wearing a great coat and a serene smile.

That’s my read on Denji’s love life: some sweet possibilities, a couple of booby-trapped maybes, and a top tier of absolutely not. Agree? Disagree? Drop your ranking in the comments.
