Hey, guys. I'm back with an all new story. To start off this fanfic, I'm gonna have it be an emotional opening, even for a comedy like "Sgt. Frog." I own nothing. All rights go to original owners. No copyright intended. Please comment. Enjoy.

It was late at night, when Fuyuki heard the familiar sound of a space policewoman spinning around in circles through her teleportation portal. Fuyuki's friends were having a sleepover tonight, so they could all greet their space froggy friends, The A.R.M.P.I.T. platoon, home from their mission to another world. Fuyuki woke up his sister Natsumi, Momoka, Saburo, Koyuki, the alien girl Angol Mois, and Keroro's wife, Pururu. The female keronian chose to not go on the mission because she wasn't feeling so hot.

"Officer Poyon! What're you doing here? Did the Sarge mess up something on his mission?" asked Fuyuki.

"If so, believe me, I'm gonna discipline him good when he gets here." Natsumi clenched her fists.

"It grieves me so much to report but, The A.R.M.P.I.T. platoon is dead." Officer Poyon said.

The whole group gasped. It was like the entire world around them shattered into a million pieces, much like their hearts.

"Dead?! What is this? Some kind of a sick joke?!" Natsumi shouted in anger and sadness. She always thought the frogs were annoying, but she did admitted to liking them a teensy bit.

"Their mission was to investigate a distress signal on a restricted system to anyone but Keronian authorities. A week later, we couldn't get any form of contact with them. The Garuru platoon went to investigate, but no trace of their ship was ever found, all except a capsule, containing this letter." said Officer Poyon.

Fuyuki quickly read the letter the officer had given them. It was written from Keroro. What was written had shaken Fuyuki to his core.

"Dear Fuyuki,"

"If this letter got to you, and you're reading it, then you probably know I'm not coming home this time. I've got little time to write this, so I just want to say, you're the best friend a guy like me could ever have. Sure, our invasion on Pekopon was gonna be a big flop from the start, but it was worth it. At least, I got to know you, Natsumi, Mom, and all our other good friends. I want you and Natsumi to take good care of my niece, Mois, and my dearest wife, Pururu. Tell her I'll always love her with all my heart. Thank you, all of you, for making me the frog I am now. I'll never forget you. Good-bye."

"Sgt. Keroro"

Nothing could stop the tears from pouring out of all the kids' eyes. The frogs that changed their lives for the better were gone forever, just like that.

"My condolences." Officer Poyon bowed, and teleported away.

"Fuyuki, I'm so sorry-" "Shut up, Natsumi!" Fuyuki snapped at his older sister. Natsumi was taken aback at her brother's attitude.

"Why should you even care? You never liked the Sarge, anyway!" Fuyuki snapped again.

"That's not true! Of course I did! I just had a hard time showing it, that's all!" said Natsumi.

"More like a lousy way of showing it." said Fuyuki.

"Hey, come on, man. That's not fair to your sister." said Saburo.

Fuyuki just turned and ran back into the house, and up to his room, locking the door behind him, leaving his sister with guilty thoughts. Pururu wasn't paying any attention to what happened. She was too busy clutching the last letter her beloved left her. She cried a waterfall of tears, and only Mois was there to comfort her auntie, having lost the Keronian that was her sweet uncle.

One week later...

Saburo was in his booth, hosting his radio show. "Hey, guys. This is DJ Mutsumi here." he spoke into the microphone. "Today I got no poems to read. Only gonna play a hit song for you guys. I lost some good friends the other week, and I like this song to go out as a tribute to them, and to those who've lost a good friend." Saburo turned the record player on. All of Tokyo was filled with the sweet sadness of the tune.

"I always needed time on my own,"

"I never thought I'd need you there when I cried."

Natsumi was on her bed, listening to Saburo's show. The song made her realize just how much she cared for that stupid fro- Keroro. But, the frog she missed the most was Giroro. He always said he was the toughest of the platoon, but deep down, she knew he was sweet. If only she had the chance to tell the both of them how much they meant to her.

"And the days feel like years when I'm alone."

"And the bed where you lie, is made up on your side."

Fuyuki kept to himself all week in his room. Sitting at his desk, in his hands, was the last Gundam model Keroro ever built before he left for his mission, before he left for good. Fuyuki rested his head in his arms on the desk, and cried for his best friend.

"When you walk away, I count the steps that you take."

"Do you see how much I need you right now?"

Aki Hinata was falling in a little depression. She felt bad because she couldn't think of a way to cheer up her kids, but now without Keroro, there was no little alien that brought joy to her career and her family. She always loved that little frog as her family, and he was the inspiration for her manga, "Captain Geroro". Without him, her life seemed more grey than before.

"When you're gone, the pieces of my heart are missing you."

"When you're gone, the face I came to know is missing, too."

"When you're gone, the words I need to hear to always get me through the day, and make it okay."

"I miss you."

Momoka was sitting in her room, door locked, because she didn't want Paul or any of her maids bothering her. She just kept crying over the small locket with the picture of her and Tamama together. It was because of him, she got closer to Fuyuki. Nothing in her large mansion of a home could fill the hole in her heart for the adorable late Private.

"I've never felt this way before."

"Everything that I do, reminds me of you."

Koyuki was silently sipping her tea. She stared at the empty cushion where Dororo sat. He was the reason she had friends like Natsumi, but above all, she loved the late ninja frog with all of her heart. Her tears fell into her tea.

"And the clothes you left, they lie on my floor."

"And they smell just like you."

"I love the things that you do."

Saburo sat on his favorite spot on the Nishizawa tower, staring at the sunset. He took out his reality pen, the only gadget he had to remember his chum, Kululu, and drew sparkles on a piece of paper, before folding it into a paper airplane, and threw it across the sky, transforming the paper into a shower of twinkles that mingled with the beautiful, and sorrowful sunset atmosphere.

"Bros forever, Kululu. I hope you saw that, wherever you are." Saburo said, with a sad smile.

"When you walk away, I count the steps that you take."

"Do you see how much I need you right now?"

Angol Mois was on her way back home. She decided not to destroy Pekopon. Her uncle would've wanted that. She cried in her energy bubble all the way home. Her uncle was always there for her, but now that he was gone, who was gonna be there for her when she needed somebody to love her the most besides her own family?

"When you're gone, the pieces of my heart are missing you."

"When you're gone, the face I came to know is missing, too."

"When you're gone, the words I need to hear to always get me through the day, and make it okay."

"I miss you."

Garuru's platoon tried everything to get their leader to come out of his quarters, so they could cheer him up, but Garuru insisted on being alone. In his hand, was a picture from when he and his little brother were kids. Giroro had always looked up to his big brother, and Garuru was happy to let him tag along in endeavors to joining the Keron military. Garuru couldn't hold his emotions in any longer, and cried over the brother that always saw him as more than a big brother.

"We were made for each other, out here forever."

"I know we were, yeah, yeah."

"All I ever wanted was for you to know."

"Everything I do, I give my heart and soul."

"I can't breathe, I need to feel you here with me, yeah."

Keroro's father, The Demon Sergeant, was comforting his dear wife. Even for his reputation of being the most feared soldier in the Keron army, he mourned alongside the mother of his boy. The only son he had that was never coming home again.

"When you're gone, the pieces of my heart are missing you."

"When you're gone, the face I came to know is missing, too."

"When you're gone, the words I need to hear will always get me through the day, and make it okay."

Pururu had rejoined the Garuru platoon, not long after Angol Mois left to go home. She was in her room, holding a small stick in her hand. It was a pregnancy test, and it was positive. Pururu sobbed uncontrollably, not only for her beloved husband, but for the fact her child would never see the real face of their lovable father.

"I miss you."

"Keroro," Pururu sobbed. "Please don't leave us. Please come home. I love you."
