What would you do when you have a friend who trusts you with every fiber of his being?

Of course she would never betray him, that was the only thing she could do in return for the trust he always gives her, not like his secrets are that exclusive. Yes, he is the container of the Kyuubi no Yoko.

So what?

It's not like he is the Kyuubi and the Kyuubi is certainly not a bad creature. She had entered his mindscape once (compliments of the fox himself), and the fox did nothing but talk freely to her since she befriended his vessel. She knew very well that other than his container... she was the only human being that Kyuubi could trust, aside from Naruto.

What would you do when you have a mentally insane friend who's been suffering a mental illness since he was a child?

She? Nothing, just be there every time she could be with him. It's not like Naruto was totally insane: Kyuubi is always preventing it from almost happening.

Keyword would be almost, meaning not instantly or completely.

Naruto's mind became very fragile when he was badly beaten as a child. The villagers made sure that they smashed his head totally, just to make sure that the so-called 'demon child' would not even think of destroying the village again. Kyuubi was able to heal the physical damage to his head, but the mental scarring manifested as a defensive lapse in his mind.

Kyuubi tried to block this lapse to prevent Naruto from going insane, but only succeeded in preventing it from fully taking over. Panic attacks were found to be the only thing the demon is unable to stop; they are either caused by being beaten or mainly strong emotions that Naruto doesn't know how to deal with.

To her, it was his defense mechanism of dealing with things.

Naruto was known as the loud, goofy and annoying blonde who craves attention. But since she was his trusted friend and pillar of strength, they have been underestimating him due to her being there to keep him stable and out of everyone's way.

Thankfully, the panic attacks aren't strong enough for him to fully release this mental 'defensive' lapse. But every time it activates he would go under what she would call "Insane/Manic Mode". It was like, Naruto had a split personality of his own but he's still very aware of everything when the lapse dies down. He names himself 'Kojirou' when the lapse activates. Besides, the Kyuubi said it was the blonde's real name, not Naruto as everyone had come to know him.

He acts like the the same idiot, but the difference is that he doesn't hide his talents and obviously his feelings. The lapse seems to also go by mood disorders. The mood disorders flows in a freaking and frightening intensity. Naruto or 'Kojirou' would be laughing so cheerfully a minute ago then the moment he saw something that pissed him off he would go for lust mode that would give a jounin a run for his money.

How fun is that?

And how fun would it be when, other than her, 'Kojirou' likes to hang out with the scariest man in the village (who happened to be the Head of Interrogation Department) Morino Ibiki? And things only got worse when one Mitarashi Anko seemed to like this "Manic Mode" of the blonde. And just because of this that shinobi of Konoha have developed a fear of him becoming Ko.

She just hopes that the next panic attack he get wouldn't totally release the mental lapse. If so, he would be 'Kojirou' for a long, long, long time... or maybe forever. And she doesn't know if others could handle him. Sure she can but what about his team and fellow rookies?

What does she feel when he becomes Kojirou and into "Manic Mode"?

She always feels kind of excited and nervous at the same time: excited because he has always been very good at fighting and refuses to hold back with her during their spars; excitement because 'Kojirou' makes everything interesting. And nervous because, you would not want to piss him off: at any given moment he's very friendly... then another blink of the eye and he's your worst nightmare.

She's very thankful that they are on the same side.

Yes, Naruto was insane as 'Kojirou'. He does not hold back his emotions. If he's happy, he would openly laugh loudly thus making you doubt his sanity. If he's sad, he'll just chuckle while tears pour out. If he's mad, he'll destroy things he feels like destroying. If he's scared, he'll just stay still like an obedient dog. If he trusts you, he will openly say it. If he doesn't like you, he'll ignore you as long as he can just for him to not beat you into the ground. Now, who will say he's not insane?

For her, it is certainly fun.

Only her, the Hokage, and certain people in the shinobi corps knew about this; even his own sensei is unaware about it because Kakashi has been busy in his job as ANBU with mission after mission to even know that his sensei's son had become particularly screwy in the head.

How can you differentiate his "Normal State" from his dubbed "Insane/Manic Mode"?

Well, simple. Very simple.

Naruto would always be grinning as he tried to conceal whatever he feels and tries to act as an idiot. And he would call others by their normal names and her by her real name, "Ten-chan". While 'Kojirou', he'll let you taste his emotions freely, and would call others by insults (or by real name if he deems you worth it) and dubs her as "Kit-chan" because he claims her as his family.

For instance, when he was still seven years old and had gone to "Manic Mode": 'Kojirou' had openly dubbed Iruka as "Scar-head" which only made the chuunin blink and laugh. Not that he's not against it, it just makes Iruka annoyed. Of course, his sensei from the Academy knew this. Why wouldn't he? Iruka panicked at first, unsure of what to do. But the Hokage reassured him that this 'Kojirou' character was not harmful to anyone as long as you don't harm him or pissed him off. And this "Manic Mode" would listen to the people he trusts. Over the years, Naruto learned to trust Iruka and so did the chuunin.

What would Team Seven's reaction be when they found out about this 'Kojirou' lapse? If you were to ask Tenten herself, she would love Naruto to stay that way. They would mostly know him a fraction without his idiotic facade. But others might start to get scared of him and even avoid him. Not that 'Ko' would give shit about it, 'Ko' having become their nickname for him.

But, why did she have this terrible feeling that something is about to happen and is only getting worse? And in the back of her mind something tells her that it involves 'Ko' greatly. She shuddered a bit with that thought in mind as she continued to help her teammates in catching Tora-chan for their daily D-rank mission.

Back in Wave, the Kyuubi's chakra leaked out of Naruto. Naruto felt so much anger after Haku 'killed' Sasuke. He was so close to almost killing the boy, but then... he recognized him as the boy he saw in the woods. Suddenly, many strong emotions washed over him like a flood. He felt betrayed, sadness, anger, disbelief and misunderstanding all at once. The emotions were so strong that Kyuubi had the hardest time ever stopping the lapse. Naruto's emotions just grew more and depression came soaring in as he listened to Haku's story.

To be betrayed for something you have no control over...

To be hated for something you didn't ask for...

To be shunned like some useless trash for just being you...

It hurt. It really hurt.

The Kyuubi suddenly felt the lapse grow stronger as he finally let go. Kyuubi had never been worried in his whole life. What would 'Ko' do? He started digging ideas in his ten-thousand year old brain of his for the possibilites. The brat had finally broke down as the lapse took over and he couldn't stop it this time.

What would happen? The world was in for doom that even Kyuubi became worried. Since Naruto - or rather 'Kojirou' - doesn't hold back, 'Ko's knowledge was large enough that he learned how to control the surroundings in his mindscape thinking of many ways how to torture him, the feared Kyuubi no Yoko. It's okay if that's the only thing, but the knowledge of being summoned in a kit's body was the most humiliating thing a demon could think of.

As Haku came for Zabuza, Naruto stayed standing still there.

Quiet.

The Kyuubi became more worried the way Naruto or now 'Ko' stayed still. It's just too quiet. He never knew what happened next as the last thing they heard were villagers cheering for something. Kyuubi suddenly remembered something from 'Ko' that the kid had wanted for a very long time if it weren't for the fox stopping him. Now, he would grant this to 'Ko' as long as he stayed quiet and followed his sensei's orders. Fair trade is what 'Ko' likes best after all.

He just wished that it was enough for 'Ko', for the brat, not to send his teammates terrified or crying because of his spectacular moods and colorful string of words that would put an experienced sailor to shame. Hell, even he, the Kyuubi didn't know where 'Ko' learned such vulgar words. He inwardly shivered. 'Ko' needed to get back to the village fast to let the human girl, Tenten, to stick up with him to stop 'Ko' from raining doom.

Kakashi was a little terrified that he killed Zabuza's 'tool', especially with the brutality of the method. He couldn't help but sigh as he thought Sasuke just died but it seemed Sasuke had this "Fangirl Sense" in use which caused him to immediately wake up upon sensing Sakura. Now, as he walked over to Naruto he could see the boy was just standing there with his head bowed and his face in shadows.

He slowly approached to make sure his student was alright but then Naruto held his head as if he has a terrible headache; he watched pensively until the blonde arched his back and wrenched his head back with a silent scream before proceeding to pass out, hitting the ground like a lifeless doll.

Kakashi immediately rushed to his side with all the strength he had got left and observed that Naruto must have passed out from exhaustion. He sighed in relief as his team made it, his team survived; they completed their mission and none of them died.

What adventures are about to rain on Team Seven? Kakashi suddenly felt shivers and he didn't know why. But he had this feeling that the moment they stepped inside the village, it will be the first day of doom.

Or was it just paranoia?

Author's Notes:

I just want to write a story where Naruto would practically a fun person, where his definition of Fun is somehow related to Doom itself. I also want to make a little fuss about the characters when this new shift of personality suddenly gives their lives a little twist they will never forget.

And in this fic, Kyuubi is definitely a good bijuu. :) Please wait for the next chapters, Team 7 is in for a surprise when they get to the village!

Thanks!

I have Djinn Crimsora to thank for fixing this chapter for me. Enjoy.
