Oof I should try to post new chapters more consistently... But don't worry, no matter how long it takes I won't discontinue this fic :)

Patiently waiting to watch Kacchan's match, I sat in the stands with both Wing-san and Zushi beside me. I had no doubt in his abilities, so I was extremely confident in him, just as I'm sure he was in himself.

The commentator announced their arrivals:
"The next match for today will be Katsuki vs Ruusen! Katsuki only newly entered the 200s, however all his previous matches on the floor below had been dealt with in one blow! And his opponent, Ruusen has a respectable streak of 2-0!"
"2-0, same as Madhu... They must be working together. They've probably been targeting the newcomers for their wins, so they've only got 2 wins... Ruusen's hair is weird, it almost looks like it's floating. Could it be related to his hatsu?"

Zushi nudged me and bought me to my senses.

The announcer declared their beginning, and immediately Kacchan threw an explosion at Ruusen, who didn't seem to dodge.
As the smoke cleared from the arena, Ruusen was revealed to be... unscathed? His locks of golden hair had grown even longer and thrown themselves between Kacchan and himself, likely acting as a shield.
"There it is, Ruusen's special hair! It can act as a good shield, but also good for attacking, so well rounded in combat! Katsuki's nen must be explosions! Seems fitting for his short temper."

I didn't have to see his face to know a vein flared in his face, as he lunged forward yet again, palms crackling. Instead of using his hair as a shield, however, this time Ruusen let his thick locks of hair whip around him. This didn't deter Kacchan, who launched fist first towards the flashing ropes of hair.
"Clean hit and knock down!"
The referee was announcing for Bakugo, who's exploding fist seemed to punch through Ruusen's defence. Through the smoke, I could make out a large silhouette with no arms and long hair being knocked back.

"Feh! Is that it? All you got?"

The lion like man stood up, using his hair for what one would usually use hands for, and sent a long whip of hair at Kacchan. His hair had seemed to braid together tightly, forming a long, thick rope. Kacchan easily dodged, of course, but when the braid of hair hit the ground, the floor cracked.

"It's that strong? Of course it must've been enough to block Kacchan's initial attack, but then when his hair was lashing about, how did Kacchan get past them? Maybe they're weaker when they're apart?"

"Ruusen's hair whip! Lucky for Katsuki, he was able to dodge that!"

"So then the hair must be stronger when its braided together..."
"Izuku, can you stop mumbling? Everyone is staring at us..." Zushi said.
"A-ah! Sorry..."

Ruusen launched his hair-whip at Kacchan yet again, but instead of dodging, he held out his palm, crackling intensely and caught the lock of hair.

"Clean hit for both!"

Kacchan set off another large explosion, but before smoke filled the arena, both figures were knocked back. Once the smoke and dust cleared, I could see Ruusen's hair had begun to unravel. Kacchan didn't plan on giving him time to rebraid it, and he used an explosion to propel forward, sending a kick at his opponents stomach - he couldn't guard it with his hands afterall.
"Critical hit and knockdown!"

'Only four points left and he'll win...'

Kacchan continued darting around, landing more hits, eventually ending up 10-2, as Ruusen managed to sneak in a clean hit. The fight was over in 10 minutes - half my time.

Having won one match each, we said goodbye to Wing-san and Zushi, and left the arena to the disappointment of the audience. We caught the night train to Yorknew.

"Have you heard of that auction for a diamond, where a kid is arm wrestling but has yet to lose?"
"Yeah? I heard he's already beaten 150 people!"

"It's like we're following their ghosts, Kacchan. The kid is probably Gon or Killua."
"Of course. Those bastards. I'd love to win that diamond."

We fought our way through the crowd to, sure enough, find Gon arm wrestling with a girl who looked strangely familiar, Killua holding a diamond, and Leorio acting as a referee.

"Glasses, a golden chain with a cross at the end, short black hair... Where have I seen her before?"
"Shut up nerd. You recognise her?"
"I-I'm sure I do... I must've seen her somewhere..."
"Hah, grass-head is struggling."
"He is... the girl must be strong then... Come one, where have I - ah!"
"Hmm?"
"She's from the Ph-Phantom Troupe."
"If she is, why is she arm wrestling for that diamond, they're thieves they steal..." He'd dropped his voice to a low whisper.

Fortunately, Gon had won, so the diamond was safe. 'Or rather not, as it means she's likely to outright steal it...'

But she simply stood up and left, much to my delight.

"Gon, Killua, Leorio!"
"Izuku, Katsuki! You came!"

The other three had decided to wrap it up for the evening, so we were finally in privacy, in a hotel room.

"What were you doing?" I asked Killua and Gon.
"Earning money. I need it to buy a game which will help me find my dad," Gon replied.
"A game?"
"Greed Island. It has a starting bid of 8.9 billion jenny."
"8.9 b-billion?" I repeated.
"What kind of game costs 8.9 billion jenny?" Kacchan said.
"Greed Island, we said-" answered Gon, clueless to Kacchan's tone.
"Ok well, anyway. You know who that girl you arm wrestled was, don't you?" Kacchan asked.
"Her? No, but she was very strong... Maybe she's the world champion arm wrestler or something..."
"She's a member of the Phantom Troupe," I said.

There was a pause.

"Wait what?" Leorio broke the silence.
"How do you know?" asked Killua.
"Of course he knows, he's a nerd," said Kacchan.
"The Phantom Troupe... they're the ones Kurapika's after..." commented Gon.
"Actually, have you seen Kurapika?" I asked.
"No. He should turn up soon though, the day's almost over," said Leorio.
"Ah! How did you two find us?" Gon asked.
"We followed the rumours," I answered
"Yes! It's working!" Leorio cheered.
"What is?"
"The stories are spreading nicely."
"Stories?"
"The arm wrestling was just meant as bait, to lure out the moles," grinned Leorio.

Leorio finished his explanation of what he meant. So I decided to begin to explain my situation.

"Have you learnt nen Leorio?" I asked.
"Of course!"
"Ok, good. So... uh... Well - see Kacchan already knew how to use nen, he just hadn't developed a hatsu-"
"Hatsu?" Leorio asked.
"He barely knows nen. He only understands ten, so you'll have to explain everything else, too," sighed Killua.
Reluctantly, I had to make a quick explanation on the four principles of nen. Then I could get into the details.
"Ok, so, Kacchan has developed a hatsu already - he's a transmuter, he transmutes his nen into nitroglycerine to make explosions."
"Ooh, cool! Can I see?" said Gon.
"Not now." Kacchan growled, catching the other three off guard with his aggression. I could tell he still felt guilty, even after I had reassured him. He beckoned for me to continue.
"So...W-well... I mean, we grew up together, so I learnt nen too..."
"Then why didn't you use it at the exam?"
"Ah. W-well Kacchan only recently figured out his Hatsu, but see - I'm a specialist - and something happened to I developed a hatsu quickly. It was a healing hatsu. But then... I-it was stolen."
"Stolen? How do you steal Hatsu?" Gon asked curiously.
I bowed my head. "Do you know the Phantom Troupe Leader's hatsu? He's also a specialist, and he can steal other's hatsu."
"Wait... don't tell me your nen was stolen by the leader of the Phantom Troupe?" said Killua.

Kacchan's head was bowed in shame. The other three had their eyes wide in disbelief. I closed my eyes, taking a deep breath, and continued.

"Yes. My hatsu was stolen by Chrollo Lucilfer."

Sorry for the short chapter. Thanks for reading, favouriting, following and reviewing! Thank you all for the support! :D Reviews brighten up my day, so if you want leave a review, then go ahead, doesn't matter how long or short :)

Also, I'm gonna pull a Togashi and go on hiatus. Yes, I know I've essentially been doing that anyway... but I've got exams coming up so I need to prepare so this time it's an official hiatus. I don't know necessarily how long it'll take, and even with this, I will still try working on the fic during my free time, so who knows, maybe the next chapter could be out soon? (Unlikely). The next chapter will definitely be up before August, which is a long time away granted, but that's more of a worst case scenario. Thank you for being patient!

Guest: Thank you!

D3lph0xL0v3r: THANK YOUUU! Yes, I sincerely hope he does too (yes, I am writing the fic and yes, I do know do what will happen lol).
And yeah, Hisashi Midoriya as Ging... Haha, that'd be pretty intriguing. Izuku could have a positive effect on Gon, and maybe he wouldn't be as selfish or hypocritical as he is canonically, and Izuku could save Kurapika, I mean we all saw what he did in the sports festival to Todoroki (and now in this fic with Killua :D).
Yes! I thought it was only fitting to have the saint Izuku himself to have a healing hatsu, something that would be pretty enviable to others. As for the exact abilities, yes he can heal himself - I was thinking his specialist ability was something akin to 'sharing nen' and his nen has healing capabilities, like how an enhancer has enhanced healing abilities, but his specialist ability also accentuates this so it's more effective. Bakugo's nen was actually based off his quirk,but his quirk is based off his personality (or maybe the other way round) so his ability, I would say, is based on his personality. But his nen type according to Hisoka's test isn't, if it was he'd be an emitter seeing as he's very short-tempered.

Guest (30/3): Yes... I'm sorry it's taking so long... Thanks for reading though!
