A weak after the end of the war.
Nagi lay on her bed. "I still can't believe that everything is over. I wonder how Mukuro-sama is doing." She closes her eyes to see his face the moment he told her about his feelings. "It's a stupid idea to love someone like me."
Namimori Street.
A man with yellow hair and black eyes walks in the street with two men behind him. One was with black hair, the other has red hair.
"So." The yellow haired man says. "Nosaru lives here?"
"Well, how can I know?" The black haired man answers. "You know that Nosaru was supposed to be dead 28 years ago by Calore's hands."
"I know that she is alive." The yellow haired man says. "You know how much she is strong, that Calore couldn't kill her. Even if he killed her family. Let's go!"
"Yes Nero!"
Kokuyo Land.
Mukuro sat on his sofa holding a gift in his hand. "I don't believe that I bay that gift. How will I give it to her?" Nosaru comes to the room to see her son. "Bad timing! How will I give it to her?"
"What are you doing?" She asks.
"Well… I… Nothing important!" He says.
"I see. A gift for Nagi?" She asks him with a playfully voice.
Mukuro blushes. "No. If I buy a gift for her, her husband will bite me to death." He smiles and look to his mother. "It's for you. Today is your birthday!"
Nosaru laughed after hearing Mukuro. "It's seems that I forgot my birthday like always!" Mukuro laughed at her reaction. "You don't laugh like this for a long time, Mukuro. Let's get out from here and have some fun."
"Well, I…"
"I won't listen to you." She holds his hand. "You will come."
…
Nagi leaves her house, she was going to work. Nagi sees that guy Nero and the two men behind him. "Who is that?"
"I really want to meet Nosaru!" Nero says.
"Eh?" Nagi heard him. "What does he want from Nosaru-san?"
"Who are you?" Nero stops and looks at Nagi.
"Eh? What?" She asks.
"I can feel something strange about you." Nero says.
"That's true!" The black haired man says. "You resemble Nosaru!"
"What are you talking about?" Nagi asks. "Who are you?"
Nero's body becomes black, his eyes are empty, and he attacks Nagi. His attack is blocked by a trident. "Ku fu fu fu. Maybe I will have some fun." Mukuro blocks the attack.
"Mukuro-sama!"
"Stay behind me." Mukuro says and gave her a warm smile making her blushing. "Who are you? What do you want from Nagi?"
"Nothing, I'm looking for Nosaru koketé."
"Why?"
"I want to have some fun with her. I want to have a fight with Nosaru!"
"I see." Mukuro prepare his trident. "I don't think so."
