Chainsaw Man: I'm the Diva, Right?

In the world of Chainsaw Man, Hasegawa makes a contract with the Giant Clam Devil. From then on, he can draw his mighty sword and turn it into a weapon to fight devils! But too much of a good thing can be dangerous. If his mighty sword ever breaks, everything that makes him a man will vanish with it!

Devils run rampant, but as long as a creature known as a [Man] still exists in this world, Hasegawa will never fall! And so begins the grand serial of a legend feared by both devils and men!

Panty Devil? Taken out in a second! Homelander? Taken out in a second! Gun Devil? Taken out in a second!

Makima: "That... your belly's going to swell, isn't it?"

Reze: "Actually, I've never taken health class either..."

Teammate: "Hasegawa, you bastard! Give my little brother back!!!"
