**The SMT wiki says "In the True Ending, Minazuki disappears and Sho inherits Tsukiyomi from the plume."

Being alone sucked.

Well, everything sucked...but being alone sucked the hardest.

Sho used to prefer being alone. He had no need for people and their friendship and their bonds and all that happy horseshit. Watching Narukami and his teamsters cavorting around for a year like they truly enjoyed being stuck together made him want to puke. He didn't need pussified punks, or pint-sized private dicks, or cyuuuuute bimbos or bears. He didn't need anyone.

Except for him.

And now he was gone.

Minazuki, his better half. The only semi-decent thing his "father" had given him. He understood how Sho had felt, listened to him when he seethed and raged. Hell, he even insisted on teaching Sho to read when he'd finally gotten tired of the boy constantly demanding to know what all the charts around him said. When they'd failed the final test, when they were no longer of any use to Ikutsuki and his lab coats and were just shelved away like a toy they'd lost interest in, he stuck around. Engaged the boy. Listened to his desires and whims born out of pain and suffering and reassured him that yes, their time would come. Minazuki was the only one who truly cared for him. And then the bastard went and sacrificed himself! Now Sho was truly alone!

...wasn't that what he'd wanted, though?

What did he want? When he first awoke, the only thing on his mind was revenge against his tormentors and Dear Old Dad. When he found out the old man was dead, murdered by Kirijo, the goalposts shifted. "Kirijo" was the name he'd gotten sick of seeing everywhere. They owned the lab, the hospital...they apparently owned half the universe. Now Kirijo had taken away the one person Sho had any kind of connection with – which meant they would pay.

The problem was, he had no idea how to find them because when he finally set foot outside the hospital...the world was crazy. Again, Minazuki was the one who helped him cope. He understood how buying things with money worked – as evidenced by the earful he gave Sho after the latter swiped some food and clothes he found outside someone's house. Ikutsuki had a crappy shack he wasn't using anymore since he was dead, so Sho and Minazuki began holing up in there, trying to figure out their next move. This meant they were staying in Inaba – wherever the hell THAT was – and it sucked. This place was an armpit! Nobody did anything except live their pathetic little lives. There was no one to fight, and this was bad news, because Sho lived for fighting. His Plume of Dusk was constantly whining and if he kept swinging his swords at the walls, he'd end up with no place to hide away from the world he never even tried to understand.

And then, two things happened.

The first was this weird blue door that popped up when they were tramping around downtown, looking for something to do. When they walked by, the Plume started freaking out. Minazuki wanted in, and threatened to take control if Sho didn't comply. There was some awful singing and a chick in a blue dress who smiled at him the same way Ikutsuki did when he destroyed something fast enough. She said something about a "journey" and that he was going to be their "guest". What is this, a kidnapping? Then she said he had "a great task to accomplish", and Minazuki got him out of there in a hurry. Sho bitched about it later, but secretly, he was glad. He didn't want anything to do with more adults with an agenda. They wanted to use him, just like all the scientists wanted to use him, and when they were done with him, they'd probably toss him into the garbage like the scientists did, too. The hell with that!

The other thing that happened was the Midnight Channel. Sho didn't really care about neighborhood gossip, but it was the most interesting thing to happen in a while, so he checked it out. When some lady ended up dead, hanging from a TV antenna, his interest was piqued. Finally, some entertainment! Minazuki agreed; Tsukiyomi was just begging to be let out to play. Did this have something to do with Ikutsuki's "Shadows"?

There were kids his age here. The last time he'd saw kids his age, they were in hospital gowns, and they disappeared one by one. These kids were aggravating his Plume. What did that mean? Did they have power? Were they...like him? Minazuki singled out one: the bowl-cut. He was the leader, and he intrigued Sho like no one else. Competition. Someone to fight.

There was only one problem.

They all stuck together like a wad of chewed gum.

Sho watched as they pranced around town playing cops and robbers with a real cop, and it fascinated him how annoyingly cloying they were. They trusted each other. They all put their faith in Bowl-Cut. "Partner". "Big Bro". GAG ME!

Do you think they'd accept you? Minazuki had taunted. Do you want to be a part of their little band of best friends?

No. 'Course not. Shut up!

All that power, and what were they doing with it? Being boring? Now the guy who was hanging up bodies, he knew what the deal was! Power was meant to be used. Of course, he was defeated by the power of wuuuuuuv! What a letdown. People were useless.

The voice that came to him that following spring, however, would be very useful. Very useful indeed.

Kagutsuchi had robbed him.

The demon had promised Sho would get revenge on the world for kicking him around, and Minazuki said it was a good plan. Sho was ambivalent until he heard who was involved: Mitsuru Kirijo. Kirijo had to pay. Ikutsuki had left detailed notes and puns about what went down before he died – the end of everything, huh? Good one, Daddy-O! – and now Sho knew what he had to do. He'd get Kirijo, Narukami, and the entire world all in one fell swoop.

Now to figure out this TV World bullshit. The "Investigation Team" wasn't going to help him out. The world was all bubblegum and sprinkles to them. What about that Adachi guy? Surely he didn't care for this world!

…..

Adachi was an asshole. "Games?" "Rules?" Fuck that shit! This world gave you the shaft, asswipe! Why are you protecting it? Fine, fine, whatever! Forget Adachi! They were already so close to ending it all. None of these goodie-goodies were smart enough to figure out that fighting the Shadow clones was taking a chunk of their Personas. Kagutsuchi nearly had everything he wanted, which meant Sho was going to get everything he wanted, which meant...well, that had to be something good!

No, it wasn't. IT WASN'T AT ALL.

Kagutsuchi managed to outwit Minazuki and a battle of the bastards took place with Sho's own body! WHAT IS EVEN HAPPENING RIGHT NOW?!

There wasn't anything Sho could do or even think clearly as Minazuki assumed control and took the brunt of the god's anger. He ended up blacking out, and when he woke up, Minazuki was gone. Just like that.

But he left Tsukiyomi.

The Persona was still in the back of Sho's head, just waiting to be summoned. He could feel a presence humming to him whenever he thought about bonds or Scrap or Saint Narukami...even Kirijo. He had this power available to him now, and he didn't need to argue with another personality in order to access it. There was only one problem: he couldn't figure out how the hell to do it! Why the hell couldn't the strength of heart that enabled you to kick ass come with instructions?

He tried. He talked to the thing, ordered it, begged it, threatened it, pleaded with it. He would pace around his half-house thinking of bashing in Narukami's smug face and willing the power to do so to come to him. All it did was give him a headache. This SUCKED!

Then Sho remembered something else. Ikutsuki had left the names of a few people who had been involved in the experiments that were supposed to keep an eye on him while he was a vegetable. One of them was even in the hospital where he'd woken up; a guy named Tsukuda. If he'd been there during the Plume-shoving, maybe he would have some answers as to how this shit worked. And if not...well, Sho could still carve people up without magical powers.

…..

He never should have trusted another adult.

Tsukuda took his sweet time "researching" how to get Tsukiyomi to work. All he really did was make Sho's head hurt so badly that he puked. He claimed he needed to work it out with other warm bodies and if Sho wanted help, he was going to have to get them. Fine, whatever! Sho didn't even care about himself most of the time – why should he care about other people? The only problem was that people didn't exactly flock to him. He tried talking to some brats playing in the dirt, and they ran for an adult. He'd have to sneak up on them in order to throw a sack over them.

This was the part Tsukuda did help him with: Shadows. He said that kids could understand Shadows and the Shadows knew what kids really wanted. While they were sleeping, the Shadows would lure them out of their homes, leaving them vulnerable to kidnapping...while they were napping kids! Ha! That was a damn good one. He should start writing these down.

But the bastard didn't keep up his end of the bargain. He threw a few drugs Sho's way, took the kiddies, and vamoosed. Then Narukami and his friends started sticking their noses into everything. That machine hurt like hell, something he'd almost forgotten about. His brain felt like it was about to bust out of his skull. Why did Minazuki leave him to suffer like this?

When Sho came to, he found himself on the outskirts of the city, so he just kept going. He had to find that mad doctor and beat the information out of him, and he'd prefer to do it in a place where Kirijo couldn't drill into his psyche. He'd made it pretty far before Lover Boy caught up to him. What was that guy on? He sure was scared shitless when everything turned green. So this was that "Dark Hour". Corny. It was like some fake haunted house: OoOooOOh, coffiiiinnnnssss...sOOOo scawwwy! Once Sho had been dragged back to Inaba, however, even he had the decency to be properly scared. The Shadows knew who had been jerking them around. They came to collect his ass.

And then Kirijo healed him and took his place.

He didn't stick around after that.

She was stupid. She gave up her own life for someone else, someone who hated her. She jumped into a pile of Shadows for dumb shit like "friendship", "justice", "love"...and she saved his life. The kid who would have shoved her into the path of a moving car without a second thought. He hated Kirijo, and she hated him back...but she let him live. No, she MADE him live. Nobody asked him if he wanted to die or not. Now he was alive, and Kirijo wasn't, and everyone who loved her was gonna hate him even MORE for the rest of his life.

Time to take off again.

Tokyo was still insane. How did Narukami live here and not end up hating humanity as well? He wished he'd found out where the asshole lived so he could threaten his parents for information...but as far as he could tell, the good guys didn't know where Tsukuda was, either. Dammit, hurry up! I thought you were all smarter than this! Ugh, this made his head hurt!

Hunger forced him to interact with others. Most of the food there sucked, but there was this one goofy-looking pizza place that intrigued him, so he went inside. The people pissed him off, but the swords they had on display were intriguing. He coveted that big one. It took almost all the money he had, but he coerced the owner into sending him a sword that DWARFED Narukami's little butter knife. Ha! Now to go find Mr. Good Boy and slice him in half!

…..

But Tsukiyomi wouldn't let him. His head hurt too damn much to think of anything besides Kirijo and the look on her face as she died, so he went home and just sulked in the dark. Tsukuda wouldn't answer his calls. Where the hell WAS he? The meds were starting to run out, and going to Junes meant he risked being recognized. Psh, nosy brats!

Finally, skulking around the hospital conjured up results. Sho was eavesdropping by a window when a receptionist took a phone call. "Inaba Municipal...oh, my, the illustrious Tsukuda has remembered us mere mortals! Having fun, wherever you are? Supplies? First you disappear without any thought for your patients, and then you expect us to just ship you SUPPLIES?" She began scribbling something down on a notepad. "Oh, I'm sending you something, all right – I'm sending you a piece of my mind! Just who do you think you are, you overblown-" The other end must have gone dead. "UGH!" the receptionist groaned as she slammed down the phone. She stomped off towards the water cooler, and Sho wasted no time hopping through the window and snatching that pad. So Tsukuda wanted to hide somewhere, did he? Well, Sho had the perfect place in mind!

It was a great plan, until it wasn't.

Adachi still had a working Persona. Adachi knew how to use the TV World to dispose of his problems. Step 1: Have Adachi toss Tsukuda into the TV until he agreed to help Sho. Step 2: get Tsukiyomi back. Step 3: Murder Tsukuda and Adachi.

Adachi bitched all the way down, but he went ahead and got the place "ready" for the mad doctor. He would wait inside the TV World and keep the Midnight Expressway open for Sho to send Tsukuda on a one-way trip to Hell. Now all Sho had to do was deliver...which was easier said than done. He'd canvassed Inaba looking for the bastard, while fighting off skull-cracking migraines, before finally scoring that address. But it was in Okina City! Sho was not about to ride a bus filled with people he couldn't kill while in pain. This meant hoofing it.

By the time he'd finally dragged his ass out there, it was too late. The other Persona-users had gotten there first, and the place was on fire. DAMMIT, why were they always getting in his way?! He needed that asshole more than Kirijo did...HE was the one who was going to kill him!

Sho followed the trail of destruction until he came to a basement filled with broken machines that looked painfully familiar. He's making more puppets. He was going to double-cross me! Anger had him seeing red. NO ONE DOUBLE-CROSSES ME!

A gasp in the corner of the room told him he wasn't alone. Well, would you look at that? Here was Tsukuda with a crater where his heart should have been. Somehow, he was still twitching. He might have even recognized Sho as the boy bent down to sneer in his face.

"Oh, no. You aren't going to die...until I kill you."

- ppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppp -

TLDR: Two guys sharing a soul leaves that soul unstable when one takes off. Sho goes to Tsukuda for help. Tsukuda agrees on one condition; Sho kidnaps some kids for him to experiment on. Surprise, surprise, Tsukuda's a liar, and he somehow yoinks Tsukiyomi. Sho seeks out Adachi to help him throw Tsukuda into the TV World until he agrees to make everything right again – only he finds Tsukuda near death, and the TV World turns his deepest desires into a chaotic place. Sho's been hiding out until whatever's going on with the Shadow Operatives resolves itself and they come back to Inaba.

The thing about our other Persona users that sets them apart from Sho, even the weaker ones, is that they train. SEES had professional advice, and among the IT, I'm pretty sure Yu and Naoto would put their heads together and strategize about skill levels, specialization, balancing offensive, defensive, and healing spells. Sho is just all fight, no mercy. Who taught him to summon? He doesn't have an Evoker. He's just "GRR! ARGH!" like Takaya. It's not surprising that he'd burn himself out quickly. Minazuki was the brains of the operation, the impulse control, and now he's gone.
