Hyperdimension Neptunia belongs to Compile Heart, Idea Factory, Sega and whomever else worked on it.

"Hey, Neptune..." Nepgear spoke up as she came across her sister. She sighed as she saw Neptune's almost listless look. "Come on, it'll be okay. You'll see Peashy again some day. I'm sure that she'll be back." The fact that Peashy and Neptune had a fight before they had to rush out and save Compa and IF from this world's version of Arfoire, only to come back and find Peashy was no longer there only hurt Neptune.

'On the other hand, IF is practically hero-worshiping Neptune right now.' It was kind of cute, especially when the little girl had gotten so terrified of Plutia in HDD that she had wet herself. 'Not that I blame her.' Nepgear's expression soured somewhat, both at the thought of what she had gone through and the fact that Neptune hadn't even tried to stop it.

Of course, Nepgear was conveniently ignoring how Neptune had to keep Noire and Blanc in check when it came to Vert, since they were eager to rub the busty CPU's nose in her defeat and dealing with them and Iris Heart was too much for her.

Neptune looked at Nepgear and sighed again as she slowly stood up and made her way to the door. "Nep Jr., I need to be alone for a little bit, okay?" Nepgear stared at her sister in dismay. The look of sadness, the utter defeat in her voice just made Nepgear's heart ache. "I just need to go for a walk, okay? I just want to clear my head is all."

"...Okay." Nepgear said softly as she watched Neptune walk off. She shivered, a cold chill rushing through her at that moment. "Neptune!" She called out, causing her sister to stop at the door and turn to look at her. "Please be careful."

"Don't worry about me, I'm the protagonist." Neptune gave her a small smile before leaving.

IF watched the whole thing with a look of worry on her face. "Nep-ko..." She whispered to herself and nodded. As soon as Nepgear had turned away from the door, IF ran off after Neptune. She knew it hurt to have Peashy missing, the blonde was like a sister to her and Compa.

As much as it sucked that she had peed her shorts when Iris Heart had tormented that big meanie that had kidnapped her and Compa, at least Neptune had shown her a really cool and awesome side.

It only took the young girl a few minutes to find Neptune at the park that she had taken IF, Peashy and Compa to multiple times over the years to play on the swing sets, sandboxes and monkey bars. "Nep-ko!" IF yelled as she got close to the depressed looking CPU, who was sitting on a swing.

Neptune jerked in surprise and looked up to see IF running towards her. "Iffy? What are..?" Her eyes widened as IF suddenly launched herself at Neptune and drove her head into the CPU's stomach, causing her to cry out in pain and fall off the swing and onto her back as IF landed on her. "OOOF! What the nep?!" Neptune groaned and looked at IF, who was rubbing her head and pouting.

"No being sad!" IF gave her as stern of a look as a five year old could. "Compa's sad! I'm sad! We're kids! You're a CPU! You can't be sad! Because..." IF started sniffling and tearing up. "If you're sad then all I can be is sad and then Compa gets sad and then your sister gets sad and then everyone else gets sad and..."

Neptune blinked several times before smiling at her and sitting up and hugging IF. "Thank you." She whispered to the little girl. "I needed to hear that." After letting go of the hug, she stood up and grinned at IF. "You're right! If I'm sad, then everyone will be sad. P-ko's gone, but she's not forgotten, right?" IF nodded and smiled. "We'll see her again. I'm sure that she's okay."

IF smiled brightly. "Yeah!"

Neptune smiled back just as happily. She wasn't sure if they'd ever see Peashy again, but at least this gave them both hope.

'Besides, what kind of main character can I be if I'm down in the dumps?' Neptune asked herself as she and IF left the playground for the Basilicom. There was still stuff to do after all.

For IF, it was nice to see Neptune back to normal, even if she was hurting. After all, Neptune was more than just a hero to IF.

The CPU was the closest thing IF had to an actual mother. She couldn't stand the thought of her mother being sad.

They would eventually meet Peashy again, but it would take a long time.

But that's a story for another time.

Happens after Peashy is taken by the Seven Sages but before she becomes Yellow Heart.

Sorry this is super short.
