Chainsaw Man part 2 just gave us three chapters in a row where Denji did something that no one anticipated coming. He is fleeing from Yoru. To be honest, it may be the best thing he has ever done.
When Yoru believed she had won everything in chapter 222, the battle began. Chainsaw Man was reduced to a charred corpse on the ground as a result of her creation of this bizarre universe where no one could perish. However, Denji came out of Pochita’s body and flashed her a peace sign. He said she couldn’t turn him into a weapon because he beat her in rock-paper-scissors by choosing scissors. The shocked look on her face was priceless.
War only wins when you decide to fight

Here's the thing about Yoru that makes her dangerous in Chainsaw Man part 2. Her powers work on a simple rule. When she wins a battle both physically and mentally, she can turn her opponent into a weapon. But Denji figured out the loophole. If he never gives her that clean victory, she can't claim him as her prize.
What then did he do? He changed into Denji Man, a new red form that fused his own intelligence with Pochita's might. And he began acting dirty instead of charging at her as she had requested.
He captured devil heads with chains and made them into armor. Yoru genuinely cared about the Moray Eel Devil, one of their heads. Denji forced her to watch as he ate it in front of her after she unintentionally shot at it.
That's when the pattern became clear in Chainsaw Man part 2. Denji had no intention of defeating Yoru in battle. He wanted her to know what it was like to experience loss. He told her that losing friends only gets worse when you have fewer of them left. It was brutal and calculated.
Running away is Denji's best strategy in Chainsaw Man part 2

Throughout the most recent chapters, Yoru continued to try to force a true fight. She launched the American flag at him after transforming it into a homing spear on the moon. As it pursued Denji around the city, the weapon impaled other devils and destroyed structures. However, he didn't stand up and fight even after being struck several times. He simply continued to move.
The real turning moment in Chainsaw Man part 2 then occurred. Denji had been consuming the devils that Death had given him, believing that he was collaborating with her. Yoru was literally immobile after he devoured the Legs Devil.
People began to crawl around, birds dropped from wires, and the War Devil was abandoned on a rooftop. She had to plead with him to stop. But Denji wasn't done messing with her. When Yoru managed to force him to puke up some devils by ramming a chainsaw motorcycle into him, he just kicked her away and ran off again.
She tried to bait him with more devil pawns in Chainsaw Man part 2, but he wasn't interested. Instead, he jumped straight into a door leading to hell, with Yoru chasing after him.
The community has been picking up on what's happening too. One person pointed out that war only wins once you've decided fighting is your only option. Denji refuses to give Yoru that satisfaction in Chainsaw Man part 2.
Another fan called him the perfect baiter, and honestly, they're right. He's been using deception this whole time, something that goes against everything Yoru stands for as the War Devil.
Why this approach might actually work

Think about what Yoru actually wants from this fight in Chainsaw Man part 2. She doesn't just want to win. She wants a warrior's victory, something honorable and definitive. She lost to Pochita back in hell, so now they're tied at one win each. This final battle is supposed to decide who's stronger once and for all.
But Denji isn't Pochita. He's using meat shields, eating devils to erase concepts, and literally running away at every opportunity. For someone who longs for a real combat in Chainsaw Man part 2, it is unjust and annoying. And that's precisely why it could be effective.
Here, violence was never going to be the answer. For a conflict to begin, there must be at least two parties involved. The entire system collapses if one individual refuses to participate on those terms.
Denji is having his highest IQ moment yet by realizing this in Chainsaw Man part 2. Now they're both standing in hell, staring into a black abyss. Yoru still wants her fight. Denji is probably already planning his next escape route.
Conclusion
The question isn't whether he can beat her in combat anymore. It's whether he can keep avoiding that fight long enough to find another way to save Asa and stop the War Devil for good.
Running away might sound like cowardice, but in Chainsaw Man part 2, it's looking more like strategy. And it's driving Yoru absolutely crazy.
