I began my explanation. "Last night, the killer went to the room Maizono was in. in other words, my room. From what we can tell, Maizono invited that person there intending to kill them. She attacked them with the knife she'd taken from the kitchen earlier, but then they grabbed the fake sword I'd put in my room, and fought back. During the struggle, a strike from the sword broke Maizono's right wrist, and that's when she lost her grip on the kitchen knife. Finding herself cornered, Maizono panicked and ran into the bathroom. The killer went after her, but couldn't get the bathroom door open. What they didn't know was that my bathroom door got stuck easily, and there was a trick to opening it. Maizono knew about that because I'd told her, but if course the killer had no way of knowing. So instead, the killer forced the door open, took the kitchen knife, and stabbed Maizono. But with what strength she had remaining, she left a dying message. To keep the killer from noticing, she wrote it on the wall behind her. And with that, all her strength was gone. With Maizono dead, the killer began destroying the evidence. First, they took of their shirt, which was covered in the victim's blood. Then they took the lint roller in my room and cleaned up the entire area. They wanted to make sure they got rid of any trace they'd ever been there. Afterwards, the killer headed to the trash room to destroy their bloody shirt. They tried to burn the shirt using the incinerator there. But the trash room was blocked off by an especially sturdy gate, preventing access to the incinerator. So they came up with a plan to use Hagakure's crystal ball, which he'd left in the laundry room. The killer managed to throw the ball through the gap in the gate and hit the incinerator's switch. For any normal person, that'd be an impossible throw, but the killer had the confidence to take a shot. And that's because the killer…"

I then pointed at Leon. "Was the Ultimate Baseball Star!"

"Whoa, hey!" He exclaimed.

"Let him talk, asshole!" Exclaimed Mondo.

"The crystal ball, thrown with absolute precision, hit the switch on the incinerator, which then quickly roared to life." I continued. "The killer then made his shirt into a ball and tossed it into the incinerator. Having destroyed the final piece of evidence, they left the area with, I imagine, a sigh of relief. But there was one thing they missed; part of the shirt they'd thrown into the fire burnt away and fell out of the incinerator. The killer didn't notice this, and so left behind a piece of indisputable evidence. Isn't that right… Leon!?"

"Wha-? I ju-? Huh?!" He stammered.

"It would appear that Hagakure simply forgot his crystal ball in the laundry room." I continued. "You went there to try and wash the blood out of your shirt, and that's where you saw it, right? Seeing the ball, you thought of a way to take care of everything…"

"So, Leon…" Began Kirigiri. "Do you object to anything that's been said?"

"Do I object…?" He asked before getting enraged. "Hell yes, I object! Of course, I do! I object, I object, I object! I mean, all of this is just a bunch of stupid theories! You need evidence! Where's the evidence!? Without evidence, it's all bullshit! It's bullshit and I refuse to acknowledge it!"

"Well then, I guess this is as good a time as any to present the evidence that proves you did it." She replied before turning to me. "Naegi, I believe you're in possession of that evidence?"

"I… Have the evidence?" I asked. Kirigiri nodded

"That's right." She said. "When the killer removed the screws from the doorknob, they didn't use anything from your room to do it. Instead, they must have used something that belonged to them."

They used something of their own to remove the screws…? What could that be…?

Leon shouting suddenly snapped me out of my train of thought. "I refuse to acknowledge any of this bullshit!" He exclaimed. "That's stupid, you're stupid! Stupid stupid stupid! It wasn't even me; you're making all this up! How can all of you be this much of tools?"

Tools?

Tools! That's it!

"That's enough, Leon!" I exclaimed. "The screws on the bathroom door were removed. So the killer had use a tool to do so."

"Oh, yeah." Agreed Hagakure. "I'm pretty sure the toolkits we each got had a screwdriver inside."

"Then that must be what he used!" Gasped Yamada. "There aren't any other tools anywhere."

"But the toolkit in my room had clearly never been used…" I suggested.

"That's because the culprit didn't know it was your room!" Ishimaru pointed out. "They thought they were in Maizono's room!"

"Only the boys got toolkits, so the killer naturally assumed there wouldn't be one in there…" Assumed Chihiro.

"Okay, then whose toolkit did the killer use?" I asked while glaring at Leon.

"H-Hey!" He stammered nervously. "Why are you-?"

"It had to be their very own toolkit!" I exclaimed. "Now, Leon, would you mind showing us your toolkit? If I'm right about this, then the screw driver will show some evidence of being used!"

"You've gotta be…" He began. Togami interrupted him.

"And if you say you used it for something else, you'll have to explain exactly when, where, and why." He said.

"And let me say this right now…" Began Kirigiri. ""I lost it" isn't an excuse at this point."

Leon was absolutely silent. I could only imagine the thoughts racing through his head. 'What should I do?', 'If I grab Naegi's toolkit, they'll know it's not mine.', and the obvious one:

'Crap.'

After a while, Togami spoke up. "So, you have no rebuttal?"

"Then it would seem we are finished here." Said Celeste.

"Upupupupu!" Laughed Monokuma. "Looks like you've reached your verdict! Then are we ready to cast our votes? You all have a lever in front of you. Use it to make your selection! Oh, just to remind you all: Make triple sure you vote for someone! You wouldn't want to be punished for something so minor, right?"

"I believe we're all ready." Said Kirigiri as we all reached for the lever in front of us.

After we've all pulled it (With Leon hesitating a bit), Monokuma laughed evilly.

"Okay! Then let's get excited!" He proclaimed. "Who will be chosen as the blackened? Will you make the right choice, or the dreadfully wrong one? What's it gonna be? What's it gonna beeee!?"

A large monitor over Monokuma's chair showed what looked like a slot machine with our faces on it. The pictures of us slowed down, and eventually stopped on… Leon.

We were right.
