Yumi declined Kurama's purposal and Kuronue is a 'man' by Earth's laws, but according to the Makai, he is old enough to mate, he is still a teenager.
Kuronue came home from school. "Dad?" he called to the inside of an empty house. Kuronue sighed and found a note on the coffee table. 'Kuro- Happy Birthday son...you are the best thing Kumiko left me...I'm in the city and will be turning later tonight. Love you-Dad'
He saw a remote on the table with a 'play me' note on it. "What's this?" he asked out loud. He picked up the remote and sat to watch the video. Kuronue saw his parents on the Makai, he saw the wedding dress. He saw his mom walk on two legs then four, then it faded.
"Happy Birthday my little one. I'm so sorry I left you...but hopefully your father has told you about me" said the voice.
"Mommy...?" he asked since he had never met her and doesn't recognize her voice..he really didn't know what else to call her.
"Yes, my son I am your mother. I asked your father, Kurama to set this out for you. It must be so hard to look at almost a mirror image of your deceased wife. Kuronue, you were named after your dad's best friend who's name was also Kuronue. You look just like me but with your daddy's eyes. I have to go now baby, I'll see you again one day. Be good, take a mate and cherish him or her" she told him.
"Mama...don't go! Please don't go..." he begged as the color fadded and he sat there to cry before going to her grave.
By the time Kurama came home he found Kuronue outside at Kumiko's grave, staring at it.
"Kuronue, are you okay son?" he asked softly.
"It's not fair dad...I never got to know mom...I only really know her from what you tell me of her...the video was nice to see...she was beautiful. I do look like her don't I? he asked looking up.
Kurama nodded. "This is why it was so hard for me to discipline you at times" he said honestly.
"Dad...I'm not a little boy anymore..by the laws of the Earth I'm a man and by the laws of the Makai I'm old enough to mate" he told him.
"I know son...I know..what are you going to do?" he asked, he already knew the answer but wasn't ready to hear it.
Kuronue sighed. "I don't know dad, go to the Makai and explore it, study it...come back, and maybe study things here..." he said uncertained.
Kurama smiled. "Alright Kuro, do as you must..but remember I love you, and you'll ALWAYS be my little boy. The blessing in my life" he said smiling.
Kuronue blushed. "Aw dad.." he said. "Thanks, you're the best dad I could ever ask for"
It was Kurama's turn to blush which he didn't do very often. "Come home when you can and the house will be here for you" he said.
"Wait..what? You're not going to live here?" Kuronue asked.
Kurama shook his head. "No, there's not a point to staying here if you are not here Kuro, I have no wife, you'll be be gone soon..so why stay? I am human, no longer demon, no need to stay here and live in a house that was built for your mother and I and be reminded of all the good and bad times we had here" he explained to him.
Kuronue sighed, he felt bad for his father being left all alone to fend for himself. Kurama wasn't as young as he used to be and saw the sadness and hurt in his eyes. "What if I stayed, would you stay here?" he questioned him.
Kurama closed his eyes for a moment and took a deep breath before opening his emerald eyes and focused on his son. "Look Kuro, you don't need me to tell you to go, but I will. Go see Aunt Yukina and Uncle Hiei...go exlore where your mother grew up! Please go, I'll be fine...just be careful" he told him.
"I will dad, I'll make you and mom proud" he told him as he went to his room to pack.
Kurama watched him. "You already have Kuronue, you already have made us proud..." he whispered.
Kurama sighed and went outside. "Oh Miko...I'm going to miss him, maybe I'll find a new wife...unlikey though, I really did love you...good-bye Kumiko, I love you..watch over our son on the Makai as he makes a life for himself...today is the second saddest but happiest day of my life" he said going into the house to pack his stuff.
