You had met Nazuna Nanakusa when her mother, Haru Nanakusa, left you a letter at the hospital where you had both worked years before, just as you had become a vampire. Soon after, and after you had adjusted to your new existence, Haru invited you to a bar. It was there that she dropped two bombshells: that she was marrying a human and that she was pregnant. You were speechless. Now, months later, you were standing in front of door 704 of an old building, on the seventh floor, holding the note Haru had left you as her last wish.

"I know it's selfish, but I have no one else. You're the only one I trust. Take care of her. Protect her. Teach her what you learned. Feed her thirst... Take care of my daughter. Our daughter. Her name is..."

You took a deep breath. You entered the apartment. You closed the door behind you and took off your shoes. In your mind, a dark thought: killing her. It was a mistake, an abomination. But when you opened the door to her room and saw her... you froze. She was sitting on her futon, the light from the window illuminating her. Her hair was a very light purple, her eyes a deep blue. Her face, her body, her presence... just like her mother. She was 16 years old. And her name was Nazuna.

You instantly understood why Haru asked you. And you agreed. You taught her to feed first on your blood, and then to hunt on her own. You taught her to speak, to control her strength, to fly. Every morning, you made her long braids, which she then curled and pinned into two large rings. Her bangs covered her eyebrows, and two strands hung down, framing her face, just as Haru wore them. Once you finished combing her hair, she smiled at you. You walked over and hugged her tightly, muttering, "Why? Why did you leave me, Haru? I hate you."

Years passed. More than forty. And Nazuna didn't change. She still looked the same. One night, like so many others, you were in her apartment, preparing dinner. Crispy tonkatsu with rice and miso soup, her favorite. Meanwhile, she played on her console, cursing at the screen. When you finished, you placed the tray on the floor in front of her.

Nazuna: "Finally!" she exclaimed, still staring at the game. "Thank you!"

She started eating while playing, as always. You sat on the couch, watching her. Her hands, her way of frowning, of laughing to herself... She had grown so much. You smiled without realizing it. You weren't her mother. But you were the closest thing she had.
