Kuramastumi merely smirks at the Chunin. A verbal response, in his view, isn't due yet. Now, he had gotten a step closer to figuring out Keizo Murano. Well, one step out of countless, so it seems; but hey, a step is still a step! Kuramatsumi was definitely surprised to see Murano whip out two water serpents out of his gourd. As surprised as he was, however; he wouldn't sit by and let this attack decimate him. Whether successful or not, in his view - he must retaliate. 

Hoping for the best, he weaves a number of hand-seals. His chakra once more interacts with the air outside, melting into it as if it were one with it. In an instant, a spiky dome of ice is constructed around him, hoping to shield him from the two watery creations.

The water serpents would prove to be useless against the ice dome, simply splattering against them as they made contact. That was a very smart move. It gave Murano a few thoughts about thinking up some counters to ice-users in the future. Seeing as how a dome now separated them, Murano would have no choice but to launch an explosive tag at the front of it in hopes of destroying the structure. Coincidentally, the sight of the falling ice would be used as the trigger for his custom genjutsu, Creeping Death. It wouldn't take effect just yet, so Murano simply stood by and waited for Kuramastumi to make his move.

Kuramatsumi is somewhat relieved to see that the serpents have merely collided against the dome, splashing into downpouring currents of water upon impact. It reaffirmed the notion in his mind that ice was somewhat superior to water as well. Of course, he had always heard of it, and it always made sense to him; but seeing that in action is something else entirely, for the self-proclaimed *Scientist*. 

Nevertheless, he can't say, especially in hindsight, that he was prepared for what was coming next. The explosive tag was a simple enough thing to negate; all he had to do is touch his ice dome and pour a little chakra to protrude his spikes a little more, to allow them to absorb the impact. But we all know that explosive tags only rarely seal the deal on their own.

Indeed, it is the danger they bring along with them that is infernal.

Kuramatsumi had no choice but to eye the falling ice, and thus, falling prey to Murano's Genjutsu.

Kuramatsumi would suddenly have the intense feeling as if he was about to come under attack. Not from Murano however, who was simply standing by where he had been previously, but instead from unseen enemies all around him. Shadowy figures closed in on him in his peripherals, some crawling across the training ground's floor. Were those blades they held? They were going to attack any second, he was surrounded. There was no escape. They were coming. This was the end. 

Murano played into his illusion a bit as he called out to Kuramatsumi, "I'll call them off, if you want. Just surrender." There was of course nobody to call off, but it wasn't like the genin would know that at the time.

Just like that, it turned into the most intense situation Kuramatsumi had ever found himself entrapped in. Dread filled his consciousness; as if he was subjected to an approaching attack. This attack, however, like no other, reeked of malicious intent. It had gotten applicable enough for his brain to instruct his adrenal gland to start pumping out adrenaline and flood his blood system. The amygdala of his brain has been thrust into full motion and the danger of an actual threat was imposed upon him.

He started chuckling nervously, coming to his system as soon as he could. He eyed the shadowy figures crawling under the dome of ice, holding blades. The sound of the Chunin served as somewhat of an anchor to whatever happened outside the dome. 

'*Think, Kuramatsumi, think!*' his own psyche begged. He had always considered himself somewhat of a genius. And this time, his cognition was truly backed into a corner. As if reprimanded to work in full capacity, the cogwheels of his mind started working. '*No, this can't be real. He's not going to kill me. Not out here, not in plain sight*' he continues to think to himself, with the shadowy figures creeping ever closer. And then, it dawns on him. "**It's a Genjustu! Now it makes sense!**" He chuckles maniacally, twitching nervously in place. It makes a lot of sense to the icy-eyed Fukumoto. Training his Chakra control, however, can be done in such a way.

'*What a prickly bastard you are, Keizo Murano!*' he thinks to himself, grinning at nothing in particular.

Seeing as how Kuramatsumi realized it was a Genjutsu, Murano would drop it immediately to prevent any further discomfort. It'd been awhile since a genin saw through his genjutsu so quickly, it made him realize he still had a ways to go with his techniques. "Well done! I think that might be enough for today, you don't want to overdo it, after all." 

Assuming that Kura had dropped the ice dome, Murano would stroll over to his position to offer him a handshake. "If you ever need a training partner again, don't be afraid to ask. I'm always down." 

He would train more, but he'd promised a friend that he would go to lunch with them in a bit, so that'd be it for now. Gathering his stuff, he gave Kuramatsmi a final wave before leaving the training grounds. "Seeya around!"
