As soon as Togami left Ogami's dorm room, he headed for the nurse's office on the other side of the first floor. The three girls in that room had been knocked unconscious, so a medical office was the logical place to start looking. He knew that Celeste had found the drugs she'd used on him in there, and he was sure that the mastermind would have provided enough for multiple uses.

As he reached the office, he heard the scurry of overeager footsteps behind him, and he turned to see Genocide Jill approach. He grimaced. "Why are you following me?"

"I'm here to help you search, baby," Jill said, tongue curling across her lips as she eyed him. "I've got plenty you can investigate!"

"It doesn't look like it to me." He was about to order her to go look somewhere else – but then he paused. "Is there anything you know about what happened in that room?"

"Ooh, are you gonna interrogate me?" Jill grinned. "Will you bring out the whips and chains if I swear I'll never tell?"

"Just answer the question," Togami snapped.

"Okay, we can save the fun for later." Jill shrugged. "Sorry, darling, but I don't know anything about what Gloomy had going on. She and I don't share memories, only emotions. That means you and I can uncover the truth together!" She beamed at him.

Togami scowled. The Fukawa personality was the one with the answers that he needed – but he knew that even if he could convince Jill to change back, Fukawa would be unlikely to tell him anything useful. And while Jill seemed moderately willing to be cooperative, she didn't seem to know –

Wait.

"What do you mean, you share emotions?" Togami asked, frowning. "How does that work?"

"I don't know how, just that it does," Jill said. "If one of us is feeling something, then we're both feeling it. That's why you can get a two for one deal, baby!"

"Fukawa might disagree," Togami said. "She's been displaying a great deal of animosity for me lately."

"Probably because she's too boring to know how to act on what she feels," Jill said, rolling her eyes. "As for me, I'm one hundred and ten percent proactive – no repression here!"

"So you're saying that if Fukawa felt strongly enough to want to kill someone, you would know about it?" Togami asked.

"Aw, are you jealous?" Jill laughed. "Don't worry, darling, I'd never cheat on you that way! You're still the only one I want to kill."

That wasn't exactly reassuring – but at least Jill didn't seem inclined to take action on that statement at the moment. Of course, she'd pointed out when they'd met her for the first time that killing anyone in her signature method would be stupid – but she didn't necessarily seem like that would stop her if the whim hit her.

Well, as long as she didn't seem like she was going to attack him right then, Togami decided to ignore her for the moment. There would only be a limited amount of time until the class trial began, and he had a lot that he would need to do.

He headed into the nurse's office and headed for the cabinet where he recalled the drugs being kept. However, as soon as he opened it, he could see that the only thing missing was the single dose of chloroform Celeste had used on him. There were several items that could have easily knocked out the girls, but when he checked, all the containers were full and unopened.

He frowned, circling the room and opening all the other drawers and cabinets as well. He didn't think they'd have anything relevant, but he didn't want to risk missing anything. After all, it didn't make sense that the medical supplies here would be untouched. His first thought on seeing the bodies was that it looked like the killer must have knocked everyone else unconscious somehow, and then delivered the killing blow to Hagakure after he'd collapsed – but that theory relied on the killer having a drug of some kind to use on the other three students.

But when he'd finished his search, the only thing he'd found that seemed to be disturbed was a drawer containing large sponges. Two were missing, and when he checked the trash can, they hadn't been thrown away. That did seem potentially interesting – but on the other hand, one look at the blood splattered across Ogami's room showed that no one had used any sponges there.

Togami frowned, considering what his next move should be. So it appeared no one had taken any drugs from the nurse's office. That meant that either his original theory was incorrect, or that the culprit had found another method of knocking everyone unconscious. If his suspicions about Ogami were correct, then she would easily have been able to subdue the other students – but just hitting someone wouldn't leave them temporarily unconscious. To achieve the precision that had characterized this case without causing brain damage, some other method would have been necessary.

And if that was the case, he could only think of two other places the culprit could have found such a method. Since he was already on the first floor, he headed for the storage room first.

Of course, the problem with a place as packed with items as the storage room was that it would be almost impossible to tell if anything had been disturbed. Togami scanned the shelves, trying to see if anything looked out of place, but without some idea what he was looking for, he could spend hours here and not find anything – hours he knew he didn't have.

But on the other hand, this seemed like it might be exactly the opportunity he'd been looking for. He turned to Genocide Jill, who was still standing in the doorway with her red eyes fixed firmly on him. "Search this room for anything that the killer might have moved."

"Huh?" Jill tilted her head. "Ooh, is that an order from my Master? That gives a girl all the right kind of shivers! Say it again for me, baby?"

Togami glared at her. "Just do it. Now."

"Now that's what I'm talking about!" Jill laughed. "All you gotta do is ask, White Knight!"

He doubted that – but hopefully it would at least buy him enough time to lose her. As Jill began darting among the shelves, Togami ducked out of the storage room and headed for the stairs. There was really only one option left.

And of course, when he reached the chemistry lab, it looked like he was the only one who had thought of it. He didn't see a trace of either Asahina or Ogami around, even though they were supposed to be investigating too. Though it wasn't as though he expected much out of either of them. With both Naegi and Kirigiri looking for clues in Ogami's room, he knew that the heavy lifting of the part of the investigation in the rest of the school would be on him.

Not wanting to waste time, Togami headed straight for the huge cabinet of materials on the back wall. He'd already noted the division of its contents – supplements on the left, reagents in the middle, and poisons on the right – but he wasn't sure where a chemical to knock someone unconscious might belong. To be on the safe side, he supposed he would need to check all the sections.

The left section with the supplements looked more or less intact, from what he could tell. Even when he checked the labels on the supplements, nothing suggested that it could be used to knock someone out. The only thing he could see missing was a lot of that disgusting protein rubbish that Asahina and Ogami seemed fond of. He wondered briefly whether that might have been used as a vehicle to get the victims to consume a drug – but no, that would only have worked on Asahina and Ogami.

On searching the middle section, Togami paid a little more attention than he had to the vitamins and supplements. While he hadn't had a chance to examine every reagent in the cabinet, he knew there was a possibility that some of them might have the effects the killer needed. The bottles in the glass top of the cabinet were easy enough to sort through, but there were quite a few more in the metal bottom of the cabinet. He began pulling the different containers out for a closer examination, and then setting them on the ground beside him once he'd determined they were unopened.

And if he hadn't been so methodical, he might not have noticed the discrepancy.

The containers in the bottom shelves of the cabinet had been lined up in tidy rows, squeezed into the space to fill it from top to bottom. Looking from the front, it was impossible to see all the way to the back of the shelf – but when Togami pulled out what should have been the second-to-last container, he found only empty space behind it.

A slow smile crept over Togami's face. It was possible that the cabinet had never actually been entirely full – but he didn't believe that. No, someone had taken a reagent from the middle cabinet, and they'd rearranged all the other bottles to hide their theft. It had been a clever move – but not quite clever enough.

Of course, with the way the culprit had covered their tracks, there wasn't really a good way to know exactly which reagent they'd taken. Technically, the bottles were in alphabetical order – but the number of bottles of each type of reagent wasn't consistent. If the culprit had rearranged the containers to make sure the empty space would be at the very back of the cabinet, they could have taken a bottle from anywhere.

Still, at least he knew they'd taken something, which was evidence in support of his theory. Whatever they'd taken, it was almost certainly something that could be used to knock someone unconscious. Possibly Naegi would even find traces of it in Ogami's room somewhere.

Togami considered abandoning the chemistry lab and leaving to investigate some other location – but no, it was better to be thorough. So he turned and opened the third cabinet – and it was a very good thing he did.

A gaping empty space stared out at him, where three bottles of poison should have been.
