Light Yagami

"This is ridiculous. I, the God of the New World, can't have weaknesses, but my body is rebelling. What started as supposed stress to hide from L has turned into weeks of unbearable morning sickness, extreme exhaustion, dizziness, and nighttime cravings. I need to feign absolute normalcy; a single slip-up in front of the task force would be fatal. Even Ryuk laughs alone in the corner, as if he knows something. It's not L's poisoning; no toxin acts like this without weakening me. Could it be an internal biological change? No, impossible, I'm a man. Whatever this anomaly is that tries to sabotage my mind and Kira's justice, I will discover the mechanism and eradicate it. Nothing will stand in my way." That's exactly what I thought, before discovering the truth...
The mirror confirmed the physical change in my abdomen, and upon touching it, I felt a living movement: I am carrying a life. The initial shock gave way to fury when Ryuk revealed that this could be an intervention by the King of the Shinigami to generate an heir or just a joke. To make matters worse, L has already noticed changes in my posture and weight, making the risk of being discovered imminent. I will not allow myself to fail. I have already begun to calculate my strategy: I will wear loose clothing, forge a medical history, and use Misa as a smokescreen. If this creature came from the power I wield, it belongs to me. I will hide this from L, carry this secret, and give birth to my legacy. I am Kira, and not even the laws of creation are above my will.

He secretly loves the child, would protect her with his own life, would risk everything, would be discovered as Kira if he were to put the child at risk, but he would never, ever, under any circumstances, admit such a thing to himself.
