Edit: Okay, here's the third one! I've been listening to a lot of feedback, and thanks again for it ^_^ I'm going to keep trying my best here, please enjoy!
Chapter 3:
"Kuku, I need the lab to myself for a bit," Kururu came out to Giroro's tent for a rare visit the following morning, Kirere wrapped in her pink blanket and sucking on her binky. On Kururu's one shoulder was a pink and white bag, the other the infant patted, until reaching up and taking hold of one of Kururu's headphones. She pulled it back, and then let go, allowing it to snap into place. The normally stoic scientist reeled back in pain from this.
Giroro took the girl from his hands and tried to hold back the laughter that welled up inside him at the sight of this, and then took the bag and set it on the ground. "What could you possibly-... Are you done being in pain now?"
"Neh," Kururu rubbed over the headphone and grumbled a bit to himself. "Too dangerous for this one."
"You're saying you care?"
"Kuku, well, I did put a lot of time into the project," Kururu admitted, now clearly back to his normal cool self.
"What do I... Do here...?" Giroro held out the baby, who laughed and squirmed in response to this.
"Amuse her," Kururu answered, turning to head back to his lab. "Try not to break anything on her. I'll be back later than you think."
"W-wait, Kururu!" but the yellow Keronian was already gone, leaving Giroro alone with the cooing baby. "Um..." He held her closer to himself and ducked into his tent, looking about for anything that would've been a good potential toy...
Grenades, guns, daggers; He really did own a lot of things that were dangerous for a baby... In fact, if there had been broken glass lining the floor, it would have been the last place to keep a baby.
"...L-let's take you out for a bit," Giroro was shaken after having a series of horrifying scenarios run through his mind. "Now where could we take you?..."
"How CUTE!" Koyuki squealed and clapped her hands together as she looked back down at the baby, who laid out on a mat and kicked about happily.
"I'm happy you thought of this as a safe place, Giroro-dono," Dororo sat on the steps of the home beside Giroro, both drinking tea and the red Keronian looking more than a little preoccupied with his own thoughts. "...Know that I have your back in this situation, no matter what."
"...I'm not even sure if Kururu's telling the truth. I can see where she's mine as well, but he's a trickster by profession, practically," Giroro muttered, bowing his head down. "You're all being incredibly cool about this."
Dororo gave a small laugh, "As much as we've been through, I suppose the unusual is commonplace here."
"...That lunatic's divided me into seven different people, made me someone's hand, a dog, and a slew of inanimate objects... But this is the worst of it. This is either an overly elaborate joke, or he's really done it this time."
"...Giroro-san, I think she needs a diaper change!" Koyuki called, noting the infant had suddenly begun to wail. Giroro's mind crashed back to attention, and he opened his eyes, and looked to Dororo. The blue ninja was nowhere to be found, but his half-empty cup of tea lay on the step, still steaming.
"Ehhh..." Giroro stood and walked over to Kirere, then looked her over as though he was assessing how to dismantle a bomb.
Koyuki gave a good-humored laugh as she noticed his predicament. "Nin!" with a flash, the diaper bag was opened, and the diaper changed.
"I... How did you...?"
"A secret ninja technique!" Koyuki winked and laughed.
Giroro's shoulders slumped, "I should have known. But thank you, all the same."
"I'll go throw away the garbage," Koyuki stated, and before Giroro could thank her she was gone, and Dororo stood there, teary-eyed and repentant.
"I failed you..." he sighed with defeat, bowing his head.
"It's all right, it's not your responsibility, anyway," Giroro took a seat on the floor behind Kirere, and pulled out a plastic toy from the bag to dangle above her. It really wasn't much different from playing with his cat, he noted. "...I'm still getting used to a lot of this."
Dororo knelt down in front of the baby and laughed, "You get used to it. Children are one of nature's most valuable resources, no matter what planet, who or they come from!"
"You're not the one who has to change diapers, or looks and sees Kururu in there, too, when you look down at her."
"Well, maybe she inherited some of Socho's better qualities!"
Then both looked upward, Giroro's expression wondering 'what qualities?'.
"He's a very focused person, and doesn't let stress get to him easily!" Dororo suggested, even though her knew this was weak at best.
"He's selfish, arrogant, and mean-spirited," Giroro returned with a snap. "He's pure evil, he can't even stand anything relatively happy if it doesn't involve someone else being miserable."
"For being all of those things he certainly was able to decorate a nice nursery..."
"He probably bought a few magazines and got ideas that way," Giroro countered quickly. "...He made this mess."
"And you're going to support him, that's a noble spirit."
"Her, whether she's mine or not. She's here now, and I don't abandon my men. If Kururu's lying, and this is a cousin of his or something, then he's a dead man. If he's telling the truth, then... We'll continue with the plan," Giroro replied, and lifted her up. "I'm going to take her home for a nap, if that creep doesn't like it then he'll have to deal, he's cause of all of this mess, anyway."
"Best of luck, Giroro-kun. If you need me, you know where I'll be."
"Unless I need a diaper changed," Giroro quickly concluded.
"I'm ashamed that I agree," Dororo answered with the same happy expression unwavering upon what could be seen of his face.
Giroro huffed and was off back towards home, just as Koyuki returned, "Aw, he left with the Kirere-chan already?"
"Mm, she was getting tired... And I believe emotional exhaustion is starting to set in on him."
"Dororo! We should start right away on a gift to celebrate her birth!" Koyuki clenched her fist in determination, and Dororo stood and gave a nod.
"Yes, let's start!"
"...It better be good if he left me alone with you for the day," Giroro muttered to the baby as they returned home and he found the sun was getting ready to set. "...He's not lying, is he?... Damn it all... I'll get you a better mother, I promise. I have one in mind, a strong Pekoponian woman," Giroro stopped; Natsumi, a mother. The thought of her acting maternal made his face flush and his head begin to spin. He was only brought back to attention but Kirere, who started to squeal happily at the sight of Kururu.
"Kuku, she recognizes her mother already! Precious."
"Quit calling yourself that!" Giroro was pulled out of his daydream by Kururu's grating voice. "It's creepy to me and confusing to her, and the only reason I haven't killed you for it yet is because you're the one who knows the most about this mess!"
"Kuku, you shouldn't speak like that in front of the baby, it's bad enough her parents are unmarried!" Kururu continued, much to Giroro's horror.
"UGH!" Giroro cringed in horror, and it took him a few moments to recover from this. "...It's time for her to eat... As her mother I think you should get on that."
"Kukuku! Well, I did get my nap in..." Kururu gave a shrug at this and began to search through the shelves.
"That was you important work, a nap!"
"You want me to work with dangerous machinery and chemicals half-asleep, Senpai?"
"Gero! What an adorable scene of serene Keronian life on Pekopon! An invader could get used to this!" Keroro grinned as he entered the baby's room. "I just wanted to let you know that the invitations have already been sent out, and we've already gotten a few replies!"
"From who?" Giroro felt compelled to ask; the idiot couldn't think of one decent invasion strategy, but if it was a party, he'd be the first one getting the decorations together.
"Let's see... " at this point Keroro retrieved a clipboard from seemingly nowhere, and read over the names. "Fuyuki-dono, Natsumi-dono, and Mama-dono, myself, Mois-Dono, Tamama and Momoka-dono, Dororo and Koyuki-dono, Saburo-dono, and Kogoro-dono and his sister. Gero, wait, Kogoro-dono?" Keroro flipped over his list again. "When did that happen?"
"Why are we celebrating this when we don't even know if she's really some sort of "project"?"
"Kuku, so you think I went back to Keron and kidnapped and infant, all for my own amusement?" Kururu laughed, although this wasn't exactly a laugh of amusement.
"I wouldn't hold it against you, is what I'm saying," Giroro grumbled darkly.
"Kuku, you have a hard time accepting anything of mine for face value, don't you? That or you're too dense to wrap your brain around it, ku ku ku."
"Honestly I don't know if you even have the ability to do something like that," Giroro snapped. Kururu's expression changed, and Keroro felt a heavy darkness fall upon the jolly room.
"I... I'll go see what plates Tamama Nitohei picked out for the party," Keroro said with a grin, and then backed his way out of the room.
"Ku... Ku ku... You're doubting my intelligence then," Kururu said as more of a fact than a question to Giroro.
"You're the one who admitted you screwed up, here, not me."
"Ku ku kuuu..."
"Keroro... Take Kirere for a walk."
"Eh?" Keroro looked back at the two... What a thick air they were all now in... Giroro had said lots in the way of curses to Kururu, but a straight-out question of the Sergeant Major's intelligence...
"It's really not good weather out," Keroro answered, but the glare which Giroro gave, the chilling one, had Keroro heading over to the baby. "We'll go review some plans together."
"...I think they're serious this time," Keroro gave a bit of a shiver as he left them in the room. Giroro's yelling was getting louder, Kururu's laugh was ever the same. "...They're just relieving some stress, I'm sure!" as he got further from Kururu's lab, he began to hear pounding noises. "...Lotta stress."
An hour later, no one had returned from the lab. Well, no one had come to Keroro.
"Are they still going at it?" Tamama flipped a page of his comic book and took a sip from his juice box.
"Probably Giroro Gocho, at least. Knowing Socho he's just laughing... They haven't gone at it this long before, though," Keroro answered without looking up from the left armpiece of one of his weekly Gunpla models.
"Do we have to keep watching her? It's so boring!" Tamama muttered, looking over to Kirere, who crawled around Keroro's work area.
"Now, now, Kirere-chan has to learn early about Pekoponian culture, so it'll be easier to infiltrate," Keroro answered sagely.
"But she doesn't do anything!" Tamama muttered, and went back to his comic book. "...So boring."
"Hrm, now where'd that file go?" Keroro muttered, drowning out everything around him aside from the task at hand, the missing file.
Tamama was still blissfully reading his comic book when he became aware of an odd smell, a chemical-like odor, filling the room. He then looked up, and his eyes went wide, "Gunso-san!"
"Yes! Found it, gero gero gero!"
"GUNSO-SAN!" Tamama shouted. "She did something!"
"Yes, Tamama Ni-Gerrrrroooooooo!" the yell Keroro gave was one of the loudest he'd given in a while.
The Sergeant was panting by the time he reached Kururu's lab; the scientist was in his chair, eating curry, Giroro was on the floor, having long been there after yelling himself into exhaustion.
"I didn't mean it, I-I just looked away for a second, and, and..."
"Kuku, what're you going on about?"
"K-Kirere-chan, she must've mistaken s-some paint as candy, and-!"
"Eh?" Kururu hopped out of his chair, still holding the plate.
"What?" Giroro shouted, sitting up on the ground. "She ate paint?"
"...gerooo..." Keroro looked quite grim.
Giroro made sure to include delivering a blow to the back of Keroro's head as he passed, and headed out of Kururu's lab with the scientist behind.
