Hello, it's me here. This is a new story, I will still be updating the crossover one, but probably not so soon
Disclaimer: I own neither of the story Phantom of the Opera or Keroro, also I don't own the characters from both.
Natsumi Hinata was walking to the stage of the opera when someone tapped her shoulder, she turned around and was face to face with her best friend, Koyuki.
"Natsumi," The girl grinned, "here to see the new managers as well?"
The pink-haired girl shrugged, "I hope they're not those little Keronian though."
Just then, a group of people walked by, Aki, who was still their managers, leading two tiny people behind her, she cleared her throat for all the people to listen.
"Oh~"Natsumi groaned, seeing the two creature following Aki, "Keronians, why are they everywhere?"
"You don't mind Dororo, though." Koyuki said, referring to their ballet tutor, the little blue Keronian.
"Dororo's different." Natsumi huffed, "he brought us here in the opera house, in a way, he's like my father. Unlike the others, especially Kururu, I don't even understand how he become the tenor. "
"Everyone has already heard rumors of my retirement," Aki announced, "I can now tell you that this was all true, and to my pleasure, I introduce you to the two people that own the Paris Opera House, monseiour Keroro and monseior Tamama."
The two Keronians chuckled and waved their tiny hands to the crowd.
A young girl with bright silver hair walked out with a yellow Keronian.
"Ku~Interesting," The Keronian remarked, "I wonder how the opera ghost will react to the change of ownership."
"Oh, quiet, Kururu." The silver hair girl huffed, "I do hope that there's no more accidents..."
"You must be Mois." The green Keronian, Keroro walked to the girl and kissed her hand, Mois smiled down and Keroro blushed.
"Ku." Kururu grumbled under his breath, "Flirting with the prima donna, what a manager."
Tamama cleared his throat, "I heard that there is a song in the act three of Hannibal, maybe mademoiselle Mois would like to perform it?"
Mois's eyes drifted to Tamama as she nodded, "Of course, I would love to."
The cantor of the opera house, Fuyuki stepped out to the piano, "Are you ready, Mois?"
Mois smiled, "yes, I am, you may begin."
As the first note hit the air, most people began covering their ears, for Mois's voice was actually too pitched for them, Natsumi yelped and whispered to Koyuki, "There's no emotions in her singing, that's what my teacher said."
"But the managers enjoyed her voice." Koyuki sighed.
"They're idiots." Natsumi huffed, "At least they didn't ask Kururu to sing."
All of a sudden, the huge background dropped onto the stage, hit Mois, forcing her to the ground, all the people gasp as they saw a figure disappearing from the above.
"He's there, the phantom of the opera." horrified cries could be heard among people.
Mois was calm and gazed to the two shock manger, "A-Are you alright?" Keroro asked, walking forward.
Mois huffed and turned away. "This things do happen..." Keroro said quietly, sweat dropping from his forehead.
"Ku~This things do happen?" Kururu said, glaring at Keroro, "She won't sing for you ever again till you stop it."
"K-Kururu..." Tamama yelped, "Not you too...We will have no cast without her."
Kururu shrugged, "You hurt her, and I won't allow it to happen ever again. So,...Ku Ku Ku, try to stop it or else you're going to lose your most precious diva." He helped Mois up as the two walked away.
"I-I believe she will be back..." Keroro said, swallowed hard.
"You think so?" A voice come out from the corner, as a blue Keronian walked forward.
"Monsieour Dororo?" Tamama asked.
"I have a message, sir, from the opera ghost." Dororo said, calmly.
"Oh, come on," Keroro whimpered, "You are all obsessed."
Dororo shrugged, "He merely welcome you to his opera house, and commands you to leave box five empty for his use, and remember, his salary is due."
Tamama laughed, "His salary?"
"Madame Aki paid 20,000 Francs a month, or perhaps you could afford more, with the Vicomte of Mutsumi as your patron." Dororo chuckled.
"Monsieour," Keroro glared at Dororo, "I ought to make that announcement by myself."
"Will Vicomte be at the performance this evening?"
"In our box, who is the understudy of the role?" Tamama glanced around the crowd.
"There is no understudy, monseour, the production is new!" Fuyuki replied.
"Full house, and we have to cancel!" Keroro whined.
"Natsumi Hinata could sing it, sir." Koyuki smiled, brought Natsumi up.
"A chorus girl?" Tamama huffed, watching Natsumi up and down.
"Let her sing for you, she has been well-taught." Dororo said.
Natsumi yelped and backed a bit, "I-I am not sure..."
"You can do this, Natsumi, your teacher will be with you." Koyuki grabbed her hands, "Don't worry."
Natsumi whimpered and stepped forward, opened her mouth as the first note hit the air, "Think of me~Think of me fondly when we've said goodbye..."
At first, she was trembling, but eventually she was lost in the music as her mind and soul combined into one and she began acting like she was Elisa in the show.
"Bravo, Bravo!" Keroro applauded, "You will be the leading diva tonight!" He grinned.
Tamama nodded, "Maybe we won't lose any tickets, and the Vicomte will surely be impressed!"
At night, Koyuki helped Natsumi prepared all the costume and combed her hair, "you will be doing great." Koyuki grinned.
"I-I am still nervous..." Natsumi yelped.
"Don't be, Natsumi, I know your strength, you'll be doing just fine." Koyuki tapped her shoulder before leaving.
Dororo traveled alone down the dark tunnels, he sighed as he rowed the boat across the lake underneath the opera house, in front of him, was a lovely little house on the shore. He jumped down and knocked on the door.
A gruff voice came out, "Who is it?"
"Giroro..." Dororo sighed, "It's me."
A figure came opened the door, he was a red Keronian, with a white mask on his right side of his face, he was wearing fine suit, with a cloak on his back.
"Are you going to watch the show in Box 5 today?" Dororo asked, eyeing him.
"No, not today...with the Vicomte here, and all the people, I don't think they'll leave it..." He shrugged.
"Natsumi will surely be gorgeous," Dororo said, smiling, "with your teachings."
Giroro got out a light chuckle, "I have always had faith in her."
As Natsumi finished her last note, everyone stood up and cheered. But the one that was the most excited, was the Vicomte.
"Can it be, Can it be Natsumi?" He sang, "Long ago, it seems so long ago, how young and innocent we were, she may not remember me, but I remember her."
"Vicomte," Keroro and Tamama came up beside him, "so how is the opera? Do you like it? Maybe consider putting more money in here..."
"Of course I will." Mutsumi replied, "the opera is lovely, especially the leading lady."
Tamama grinned, looking to Keroro," I think we must have discovered miss Hinata."
Keroro cackled as they led the Vicomte to Natsumi's dressing room, "here it is."
"If you don't mind, I shall make the visit unaccompanied." Mutsumi said, bowing to the two managers.
Keroro and Tamama nodded and turned away, "They must have met before." They laughed before leaving to the gala.
By the way, let me clear out who is who unless someone is confused
Giroro- The Phantom (Erik)
Natsumi- Christine Daae
Saburo Mutusmi- Raoul Vicomte De Chagny
Dororo-Madame Giry
Koyuki-Meg Giry
Fuyuki- Monsiour Reyer (The cantor)
Keroro & Tamama- The managers
Kururu- Piange

In case someone doesn't know that, Carlotta and Piange are already couples at the very beginning of Phantom of the Opera, same goes for Kururu and Mois in this case.
