Denji could be naive sometimes. Nayuta knew that, and so did you, and you verified it a long time ago. Seven months pregnant, your belly bulging and tiredly carrying who would be the baby of Japan's hero, the great Chainsaw Man, Denji. Was this planned? No, nothing was, you two thought you had a serious stomach upset, just that, until the ultrasound showed something more than that. A little intruder in your womb. Damn.
Denji wasn't careless, and you didn't blame him, nor did he do it to you, sometimes contraceptives failed, and that 'sometimes' had now formed inside you, formed from a fleeting desire in the school bathrooms. Nayuta felt like she was almost dying, accepting your relationship with Denji for her was like accepting the fate of her own world, but this was like putting the apocalypse on her shoulders. It took her too long to accept the fact of your pregnancy, but in the end, she saw the positive side. A new follower who she herself trusted would love her like a goddess.
You spent more time at Denji's house than yours, so you decided to move into his apartment in the two last months of your pregnancy, so close to the scheduled day. Denji didn't complain, and Nayuta warmed to you, seeming more genuinely concerned about the baby. Which, they decided not to know its gender as a surprise arrival, but faithfully believed that it was a girl.
"Holy cow, she kicked!" Denji exclaimed as he felt the soft tap that came from your insides, separating the cheek that he had pressed against your belly.
"Really?! I wanna feel, I wanna feel!" Nayuta ran immediately, leaving her task half done as she ran in the direction of the two of you, sitting on the couch.
