This has to be it.

Pirro looked up at the seemingly hollow building with a determined expression. The front wall was covered in graffiti that depicted what looked like a distorted beast, maybe a badger, with glowing eyes and sharp fang.

Genkaku, the Nen Beast.

Pulling out his bokken, Pirro silently went inside.

"Hello?" Pirro called, his voice echoing in the deserted building. "Genkaku, come out quietly and this won't get dangerous!" Though Pirro knew deep down it wouldn't be that easy.

"Coming alone?"

Stifling a flinch, Pirro turned around to see a slender-looking man with tousled black hair leaning against the far wall. "That isn't smart, little boy. Go play somewhere else."

"You know why I'm here." Pirro retorted. "I am here in the name of the Hunter Association to take you down!"

"Such self-confidence. I applaud you for that. Kinda reminds me of myself when I was about your age." Genkaku stood up, smirking. "Let's see what you've got, then."

He leapt forward, an advance that Pirro easily dodged. This happened again and again, faster and faster until to a normal person it looked like two blurs bouncing off the walls.

Pirro did his best to keep a close eye on Genkaku, waiting for him to make his move. But he just kept leaping at him, following him with a sickening smirk. Pirro gripped his bokken tighter. He's toying with me!

As soon as that thought passed, Genkaku suddenly vanished from sight. Crud, I had to say something!

Before Pirro could use Gyo to find him, Genkaku appeared right in front of him, giving him a crushing blow to the stomach.

"Ack!" Pirro doubled over, plummeting to the ground in a cloud of dust.

Genkaku landed next to him, but Pirro couldn't seem to open his eyes. He gripped his stomach tightly, trying to get his breath, but the blow seemed to have driven all the air from his lungs.

When he finally got a grip, he immediately began to struggle on to his hands and knees, still panting. But Genkaku was too fast for him. He leapt into the air, landing his foot down hard on Pirro's left arm. Pirro cried out as searing pain seized it.

Pirro's breath staggered as he reached over to clutch his arm, which he could tell already was broken. As he touched it, he stifled another cry.

Quick as a flash, Genkaku brought his foot down hard onto Pirro's head, pinning it to the floor. "What a pity. You aren't very bright, are you? Oh, well…" He smirked. "Goodnight."

Suddenly, the crushing weight on Pirro's head was doubled, and he instantly blacked out.

….

Kuondo looked down at his phone, reading the text Pirro had sent him 3 days ago for the third time today.

….

Sorry Kuondo, I've got a mission, but I'll be back in a few days! I'll meet you on Monday at the D-Road park! Bring Pietro and Illuko, too! :)

….

As he headed to the park, he couldn't shake the feeling that something wasn't right. Why didn't Pirro at least text him yesterday to tell him how the mission went? Especially when he faced an opponent with that ability…

"Hey, Kuondo!"

Kuondo was broken out of his thoughts as he looked up to see Pietro waving at him. Kuondo saw him glance past him, his smile changing to a frown. He hurried over to Kuondo, confused. "Where's Pirro?"

Kuondo's heart skipped a beat. He isn't here?

"You won't find him here."

Kuondo nearly jumped. I know that voice… He turned to see a familiar man leaning against a nearby tree. "Yo."

"Ah! G-Grandpa?"

"Huh?!" Pietro and Illuko both exclaimed, looking at Kuondo in disbelief.

"Grandpa, what're you doing here? I haven't seen you in over a year!"

"Yeah, it's been a while. You've gotten pretty tall since I last saw you. You're the spitting image of Gon, I'll tell you that."

"That guy's your grandfather?" Illuko asked.

"And he hasn't cared to visit you in over a year?" Pietro added.

"Yup, that's… kinda the norm for him, actually." Kuondo turned to his grandfather, Ging. "What do you mean we won't find Pirro here? Where is he?"

Ging shrugged. "No idea. All I know is that the Committee was saying he left for a mission and never came back. They say he's been missing for two days now."

Kuondo froze. He went alone? He never came back? Could he be-? He quickly pushed the thought away and turned to his friends. "We've gotta find him! Illuko, go to the Information Center and find out where Genkaku's hideout is! Pietro, go get my fishing pole from my house! And whatever you do, don't tell anyone where we're going! If they ask, we're going to Pirro's house or something. Meet me back here!"

"Right!" Illuko and Pietro bolted, each in a different direction.

As Kuondo watched them disappear, he heard Ging's voice behind him. "You sure you wanna go through with this? You'd be risking you and your friends's lives."

Kuondo whipped around, fire in his eyes. "You think I care?! My best friend might already be dead! Nevertheless, I can't abandon him!"

Ging smirked. "You're a Freecs kid if I ever saw one. I won't stop you, then. Just don't get reckless."

Kuondo nodded. Don't worry, Pirro. I'm coming!

..

Kuondo: It's Kuondo's… *awkward silence* Uh…. Hunterpedia! Today we- um, I introduce Ging! Ging is my grandfather, and the reason my dad became a Hunter in the first place! Sure, he's hardly ever around, but I really respect him! He's a great guy once you get to know him! Ah, Pirro, where are you? Just because you disappear in the story doesn't mean the chibi you disappears, right?

?: It's G2 logic, Kuondo!

Kuondo: Wah, who said that?!

?: Now I'm a ghost!

Kuondo: But you're not dea-

?: Shh! They don't know that!

Kuondo: -_-

Kuondo: Next on HxH G2, A X Horrific X Ability! Poor Pirro! He said himself that Genkaku's ability does something worse than death! I hope he'll be okay!
