Author's Notes

Fun fact there's a Jurassic Park marathon on right now and I'm watching it as we speak.
Also, regarding Monday's episode, we need to stick together to get through all this despair.
Naegiri is going to start picking up in this chapter so hopefully that'll heal some of the pain c':
Also my favorite dinosaur is in this chapter so that's fuN
OH important note!
I started online college classes last week, so since I'm more busy now with that, updates may be a little slower! (hence why this chapter took a while to come out!)

Some useful(?) stuff:
Since the word is used a couple times and I'm not sure if everyone knows what it means:
Theropod - A carnivorous dinosaur that is bipedal.

Also, if you want to get a better idea of what the dinosaur featured in this chapter is supposed to be like, here's a video of it in Jurassic Park 3:

"What? Are you just going to stare at me?" Togami asked the dinosaur. "Your breath smells like fish and your presence is an annoyance to me… please leave."

The dinosaur growled fiercely. It roared angrily, swiftly bringing its crocodile-like head down with mouth wide open.

"B-Byakuya-sama!" Fukawa screeched, then tackled him, pushing both of them out of the way of the massive dinosaur's snout. The dino's snout hit the ground; it lifted up its massive head, roaring angrily. Its sight quickly locked onto Togami again.

"Tch! You're still not done?!" Togami stood, then suddenly bolted away.

"W-wait!" Fukawa sprang up and followed.

Without much hesitation, the dinosaur roared angrily again and fully emerged from the cover of the trees. In full view its body was quite similar to the Suchomimus and Baryonyx, only it was larger. Its main feature though was a 6 foot curved sail emerging from its back, that displayed several bright shades of blue. It definitely stood out from the rest of the dinosaur's brownish body. Not much longer after revealing its whole form, the dinosaur began running after Togami. Togami ran past Kirigiri and Naegi, soon followed by Fukawa.

"H-hey!" Naegi shouted at Togami, then turned his head back to the approaching carnivore. He tensed up, his joints locked. He was too scared to move. The large teeth and jaws of the animal… the rage in its eyes… it was truly terrifying.

"Naegi-kun." Her voice pulled him out of it. Kirigiri was gently tugging at Naegi's sleeve. Naegi looked at her, and automatically realized she was trying to tell him, "Let's get the fuck out of here," - though she would've put it in more proper language.

Naegi nodded quickly and the two began running as fast as they could, trying to keep up with Togami and Fukawa. Where Kirigiri and Naegi were just standing moments before, the foot of the sailed-dinosaur came down heavily, creating a strong vibration that shook the land and a deep, three-toed footprint in the ground was formed.

Thank god we got out of there! Naegi thought to himself.

"Look, the river!" Kirigiri said, pointing in front of them. Naegi looked and saw they were fast approaching the water. What a relief… Though this part of the river seemed more like a creek - it wasn't as wide. Naegi wasn't sure if this was even the correct river. After all, the island had multiple rivers - this might not be the one they came in on.

Togami was surprisingly a good distance ahead, farther than he initially was. He had already reached the river, and found a fallen over log that went over the river. He darted across it carefully with Fukawa scampering after him. After they got across, they continued running.

Kirigiri and Naegi reached the log a few moments later. Kirigiri wasted no time jumping on it and heading across, though she had to move at a slower pace. Her high heels were providing her a challenge to stay on the slippery log. You could tell she was rushing though. Naegi looked behind him to see where the dinosaur was. All he could see was its large head, mere feet away from them.

"K-KIRIGIRI-SAN!" Naegi shrieked before jumping on the log and practically pushing her across to the other side, where they both fell on the ground next to each other.

"Sorry..." Kirigiri apologized for taking too long on the log. Before Naegi could respond, Kirigiri was up and running again. Naegi quickly followed. The dinosaur behind them paused for a moment and looked at the river. Then, put one massive foot on the log, crushing it as if it were a mere stick. It let its clawed-foot plunge into the water, and placed its other foot on the other side of the river, crossing it with ease.

As they ran, they spotted Togami and Fukawa stopped next to a tree.

"Why are you stopped?! It's coming!" Naegi said as he and Kirigiri stopped too.

"You led that monster here?!" Togami growled, and soon enough the theropod came into view, giving off a roar as it saw them. "Tch!" Togami took off in one direction, paralleling the river.

"W-wait, Togami-kun!" Naegi ran after, trying to keep up.

As the dinosaur neared, Kirigiri took off in a different direction than the boys did.

"W-where are you going?! What about B-Byakuya-sama?!" Fukawa asked. She let out a small scream as the dinosaur got closer. She panicked for a moment, wondering if she should follow Togami, who she most likely wouldn't be able to catch up with, or Kirigiri. She decided quickly when she heard the roar of the dinosaur again, and she took off after Kirigiri.

Kirigiri looked behind her as they ran. The dinosaur stopped for a moment where everyone was just standing. It sniffed the ground a bit and looked down the river, growling. Then took off in the direction Togami went. "Interesting…" Kirigiri mumbled, before stopping. Fukawa stopped as well.

"W-what do you mean interesting?! T-that monster just went after B-Byakuya-sama!" Fukawa hissed.

"We would've been much easier to catch since we waited few seconds before running, but it went after Togami-kun and Naegi-kun instead…"

"S-so?!"

"Togami must've really pissed it off…" Kirigiri murmured, before turning in the direction Togami and Naegi went.


"T-Togami-kun! It's coming after us!" Naegi shouted.

"This is your fault! You led it to us!" Togami argued.

"N-no it would've still followed! You angered it!"

The two escaped the trees of the jungle and made it out into a clearing of grass with jungle on each side of it, except in the direction they were going. Naegi noticed the water seemed to pick up its speed, and when he looked ahead he saw a waterfall and the edge of a cliff.

"W-wait it's a cliff!" Naegi shouted.

Togami gritted his teeth slightly, reaching the edge of the cliff and coming to a halt. Naegi did the same. They both looked down the side of the cliff. They guessed it to be at least 40 to 60 feet down. The waterfall fell down into a pool at the bottom, but there were no continuing lines of river flowing from it. Naegi guessed that this must be a different river, if it just suddenly ended here… though he wasn't even sure if the river they came in on had an end to it or if it just fed off into the ocean. In the distance to their right, there was a much gentler slope that lead down to the same pool of water, but they didn't have the time to run over there.

A roar and the sound of crashing came from behind them, and they turned around at the same time. The large dinosaur had some difficulty getting through the thick jungle, but didn't give up until it burst through the trees, making a mad dash towards Togami and Naegi. The dinosaur was completely enraged.

"W-we have to jump!" Naegi exclaimed, looking down the cliff.

"No, you act as a distraction so I can get away!" Togami said. The predator was fast approaching, its head was lowering and its mouth was widening, preparing to snatch up the two boys.

There was no time to think. Instinctively, Naegi charged into Togami, pushing him and himself off the cliff; just in time to escape the grasping crocodile-like jaws. The dinosaur reached its head over the cliff in an attempt to grab them. It just missed.

They plummeted into the water and landed with a huge splash. Back up on the cliff, the angry carnivore huffed and lifted its head. It stopped to look around, seeing two humans fleeing down the gentle slope. With a mighty roar, it charged towards the two.

"L-long nose is coming after us!" Fukawa said.

"Just stick to the trees. They'll slow it down." Kirigiri said calmly. The amount of trees around them lessened due to them being next to a clearing, but there would be enough to cause the dinosaur some trouble.

The predator rammed into the trees right behind the two girls. It slid slightly as it slowed down, then quickly swung itself in the direction of its prey, charging forward. Kirigiri and Fukawa picked up their pace, reaching the end of the slope and were now running along the pool of water.

"I-is Byakuya-sama in there?!" Fukawa asked.

"I assume so… as long as they're both alri-" Kirigiri was cut off by the loud roar of the dinosaur. It was getting quite annoyed with all the trees in the way, and another was coming up right in its path. With another enraged roar and a powerful burst of speed it rammed itself into the tree, knocking it over.

"Move!" Kirigiri ordered, and the two girls split part, avoiding the falling tree. The dinosaur immediately regretted its decision, and stumbled back a bit. Dizzily, it shook its head and let out cries of uncomfort. Seeing this as the perfect opportunity, Kirigiri rushed over to the end of the pool of water and looked in. Fukawa soon joined her.

"BYAKUYA-SAMA!" Fukawa cried out. Togami's head conveniently popped out of the water as she said that.

"Is that damned lizard gone?! We can't keep hiding underwater!" Togami said.

"It's not gone but if you hurry out we might be able to get away." Kirigiri called.

Naegi's head poked out of the water next to Togami. "Let's go!" The two boys quickly swam towards Kirigiri and Fukawa, reaching them without much of a hassle despite their aching muscles. Luckily the dinosaur was still occupied with recovering from charging straight into a tree.

After struggling out of the water and standing, the boys were still a bit uneasy and stumbling after taking that plunge. All the running, jumping off a cliff, and then having to swim took a pretty harsh toll on them. On top of that they were soaked to the bone, and their clothes were dirty; Togami was very annoyed by this fact.

Unintentionally, Naegi leaned against Kirigiri slightly for support. Kirigiri didn't say anything, just gave him a quick glance then looked away.

Realizing what he was doing, Naegi quickly pulled himself away and stood on his own, his knees shaking. "S-sorry!"

"It's alright, after all you're a cold shivering mess right now. I won't blame you if you need someone to help you warm up." Kirigiri lightly teased, the faintest hint of a smirk on her face.

"W-what?!" Naegi's face flushed red. I-is she flirting with me?!

Whatever could be considered as a smirk on her face quickly vanished as an angry huff came from behind them, and the vibrations of footfalls picked up again. Kirigiri looked behind them, seeing the huge theropod trying to sneak its way over to them.

"S-Shoot!" Naegi exclaimed, then he grabbed Kirigiri's wrist and started running past the water to the other side of the jungle. Seeing the humans flee, the dinosaur picked up the pace and started running.

"Dammit Naegi! First my clothes and now this!" Togami growled, before taking off into the jungle next to him, followed by Fukawa. The dino, however, still wasn't done with Togami. It roared in the direction of Naegi, then pushed through the trees after Togami and Fukawa.

Naegi kept running through the jungle, dragging Kirigiri behind him. She was somewhat struggling to keep up, mainly because at the pace he was pulling her, she couldn't place her feet properly on the ground, and she began stumbling quite a bit.

"N-Naegi-kun." Kirigiri said. Naegi promptly stopped, realizing that he'd ran far enough and that he was just dragging Kirigiri through the woods. The sudden stop caused Kirigiri to harshly bump into Naegi, almost knocking them both over. Kirigiri quickly regained her balance though, and backed up a bit.

"S-sorry… I guess I got carried away…" Naegi refused to keep eye contact.

"It's okay. After all, you might've saved me in the end anyways." Kirigiri said. Naegi doubted she meant that though, and only said it to make him feel better; he knew very well she was fully capable of taking care of herself.

Kirigiri looked around. "Unfortunately we appear to be lost from the river again… though we weren't sure if that was the right river..."

Naegi mentally slapped himself in the face. He shouldn't have kept running after the dinosaur stopped pursuing them. On top of that they had lost Togami and Fukawa, and now they were in danger of that beast.

"I suggest we get moving again. We can't stay around the same area for too long, something might find us." Kirigiri said.

"B-but what about Togami-kun and Fukawa-san…?"

"We can't do much about it if we don't know where they are… we can only hope the dinosaur didn't catch them."

"Y-yeah… Kirigiri-san, do you know what kind of dinosaur that was?" Naegi asked.

Kirigiri looked off to the side. "Rikka did mention what carnivorous dinosaurs were on the island… she didn't give us a description of them though. Though if we use process of elimination… it can't be any of the smaller carnivores, and it wasn't the T. Rex or the two that chased us earlier… not with that sail, at least."

"Then that leaves… was it… Spinosaurus?" Naegi asked.

Kirigiri nodded. "She mentioned that he was a juvenile and was therefore a bit smaller than the T. Rex. He's definitely got a much worse attitude though."

"You can say that again… he's holding a grudge against Togami! For stepping on his tail!"

"I can't blame anyone for holding a grudge against Togami though." Kirigiri joked, though it was hard to tell since she didn't break her iron mask. "Anyways… let's head out. Maybe we'll run into them, away from the dinosaur."

"O-okay..!" Naegi agreed, nodding. The two teens headed in one direction; specifically North, but they weren't able to tell without some form of navigation device. However the farther North you go, the further you get from the park…


"That tree looks familiar! Are you sure we're not going in circles?!"

"Hagakure-kun, all the trees look similar. Though I can't guarantee we're not going in circles." Rikka smiled.

"W-what?!"

"Relax, I'll get you out of here, remember?" Rikka smiled comfortingly, almost like a big sister or a mother.

"O-okay…" Hagakure sighed.

"Does anyone have any food on them? I'm starving…" Asahina said, rubbing her grumbling stomach.

"Unfortunately I don't think any of us were prepared for this situation so… I'd say no…" Rika said. Asahina let out an irritated and exhausted sigh. After Rikka had explained the dinosaurs to them and Asahina calmed down, they started exploring the jungle again. They'd been walking for quite some time now, and they were unsure if they were even going the right way. The scenery looked pretty similar everywhere they walked, so it wasn't easy to tell if they had been in that area before or not.

A hiss of static came from Rikka's belt.

"U-uh do you have a snake or something on you?!" Hagakure asked.

"Hm? Oh no, that's my radio… my radio?!" Rikka instantly grabbed her radio from her belt and looked at it. The sound of a voice was trying to come through, but the static was overriding it. After a few moments though, the static cleared, and a voice spoke.

"Hello? Can anyone hear me?"

""K-Kenchi!" Rikka cried happily into her radio.

"R-Rikka?! Is that you?! You're here?" the apparent Kenchi answered. His voice wasn't completely clear through the radio, but they could still understand him with ease.

"Y-yeah! You're okay? Where are you? I thought radio waves and signals were blocked off…"

"I-I'm still on the island, back up in the control room… I'm assuming you're on the island too…? Something weird's going on with all the systems, I can barely get any back online… it took me all morning to fix the radio signals! Though, the signals are only running through the island… I can't get a signal from off the island…"

"Yeah I'm still on the island too… glad to hear you're up in the control room doin' your thing though!" Rikka laughed. "Anyways, are you aware of what's going on?"

"Eh… only a little… I just know everyone's missing and a bunch of systems are offline… and I can't get them back on…" Kenchi said.

"Well sir, let me tell you a thing. I wake up, I wake up the kids I'm taking care of for the weekend. We get down to the lobby, and there's absolutely NO ONE. We find a note saying to go to the river, and there's a boat there. We get on it, and this weird lookin' BEAR appears on the TV screen, tells us he's taken over, and now we gotta survive on the island for the next 48 hours! The dinosaurs are loose! We've already lost at least one… and we've all been separated into groups thanks to Sucho and Bary…" Rikka explained to Kenchi. "The bear said if we survive for 48 hours a helicopter's gonna come and pick us all up. It seems suspicious to me though… he's just gonna let us go like that…?"

"Maybe he has something planned… anyways… what's important now is getting you and all the kids to safety. Did you give each of the students a mini-tracker?" Kenchi questioned.

"Shit! I forgot to!" Rikka face-palmed.

"Mini… tracker…?" Asahina asked, tilting her head slightly.

"Ah, for big groups we typically give each member a tracking device that they can clip onto their attire. It's meant to be used by security to find everyone in your group if you are to get separated… but of course I forgot…" Rikka sighed.

Kenchi's voice emerged from the radio again. "Alright then… don't worry. I can still pick up your location here, since the radios have tracking devices in them… just let me pull up that screen…" his voice trailed off and clicking could be heard through the radio.

"That'll help us out a bit… we're still going to have to find the others though, but at least we'll know where we are." Rikka smiled at the three students with her. "I think we should start with heading to the park though and see if anyone's there."

"Sheesh Rikka, you're way out there!" Kenchi exclaimed.

"Oh god, where are we?"

"Nah, I'm kidding. You're not too far from the park. You're just past the start of the restricted zone. If you head south you'll reach River A in no time, and then following that downstream will get you to the River-Adventure queue line and I think you know the rest from there."

"Oh, good! You'll have to tell us if we're heading in the right direction before we disconnect though… if I keep my radio on too long it's battery's gonna die and I can't charge it out here." Rikka said.

"Will do!" Kenchi happily exclaimed.

"Ah, Kenchi, one more thing?" Rikka asked.

"Hm…?"

"The dinosaurs have trackers, yeah? Mind giving me the locations of the carnivores?" Rikka requested.

"Oh sure!" Kenchi agreed. A few more clicks were heard through the radio as Kenchi switched from tracking Rikka to tracking the dinosaurs. "Okay… Suchomimus and Baryonyx are down at River A next to their enclosure. The Spinosaurus is heading West of the end pool of River B… at a fast rate… huh…"

Rikka gulped.

Kenchi continued. "All the Pterosaurs appear to still be in their dome, or at least around it. Shamusaur's obviously in her tank… all the smaller carnivores - Compys, Dilos, and Raptors - they're all moving North… if they don't change course and keep going straight you shouldn't run into any of them. Just be careful about the Raptors…"

"Boy, where is my T. Rex?" Rikka interrupted.

"Oh right, Rexy! Eh… she's roaming around the outskirts of the park." Kenchi explained.

"Okay, so we'll have to be careful of her." Rikka said.

"It'll be no problem for you Rikka! After all you're the former Ultimate Dinosaur Expert!" Kenchi said cheerfully.

"Oi, oi, oi… don't bring that up, I don't know everything about dinosaurs!" Rikka said.

"Well you got that title from Hope's Peak for a reason! Anyways, just keep your radio on for the next few minutes as you walk. I'll chime in when I know what direction you're going and can tell you if you need to change or not. See ya!" Kenchi said.

"Thanks, Kenchi." Rikka said, smiling. She placed the radio back onto her belt. "Well, let's get walking, shall we?"

"Hold up, hold up! YOU'RE the Ultimate Dinosaur Expert?! You were a student at Hope's Peak?!" Asahina asked, surprised.

"Hmmm? Oh yeah! I was." Rikka rubbed the back of her head a little.

"Why didn't you tell us earlier? That's so cool!" Hagakure exclaimed.

Rikka shrugged. "Slipped my mind I guess!"

"How does that slip your mind?! What class were you a part of?" Asahina asked.

"You're the 78th class right? It's your first year at Hope's Peak then… my class graduated last year…. So this year class 75 are seniors... so that'd mean… 74th?" Rikka answered.

"You only graduated last year?! What?! How old are you even? Are you telling the truth?! I thought you said you've been working at the island for a long time! Before it opened!" Asahina was stunned.

"Ask no questions and you'll get no lies." Rikka simply said, smiling.

"Aren't those song lyrics?"

Rikka coughed. "Maybe… anyways, I'll answer your questions a hundred-percent honestly! I'm 18 years old, so I'm pretty much new at being an adult. The reason I've been coming to this island so long is because I started coming over and helping out at the end of middle school. I got invited to Hope's Peak under the title of 'Ultimate Dinosaur Expert' because of some breakthrough theories I came up with, among other things like being able to identify a dinosaur just by seeing a small bone fragment, etc. I accepted, and during that time I was only visiting the island during breaks and such. When I started at Hope's Peak I was there full-time for my Freshman and Sophomore years. During my Junior year though, Hope's Peak offered to give me credit for working at the island, so I obviously accepted that. I did come back to the school a few times, very rarely though. Since I rarely attended school the last two years of it, I was never really thinking much about it or of my title. Hearing you guys were from Hope's Peak reminded me again, though I didn't want to say anything."

"Sheesh you must really know your dinosaurs then if they asked you to come over to the island when you were still in middle school!" Asahina said.

Rikka shrugged. "I guess. I'm not always sure how much of a 'talent' my title is though, I mean, if you do enough studying and research, you could know as much as me. I'm pretty much just a sponge that soaks up information about dinosaurs. I don't think it's something that can be considered an actual talent, I'm not born with that skill." She seemed upset.

Asahina smiled. "Think of it this way Rikka! We all had to work up to be the best at what we are! So you had to work up to get that good at knowing dinosaurs. Plus, you get to work with them in the flesh and blood. I think what also counts is how good you are with handling them. I bet you're super good at it too! That it just comes naturally!"

"And you can speak dinosaur! I don't know anyone who can do that!" Hagakure interrupted.

"I don't speak dinosaur, Hagakure…" Rikka laughed a little. "Thanks though, Asahina… I get what you mean… now then, let's get going, shall we?" Rikka asked. The three students nodded and Rikka smiled warmly. "Okay then, follow me." She walked a few steps in a direction she thought was South, and the group followed.

The radio clicked. "You're headed the right way, just keep going straight till you hit River A. I'll be on standby if you need anything, so just turn on your radio and call me if you do!" Kenchi said.

Rikka picked up her radio and spoke back into it. "Over and out! Thanks a bunch, Kenchi…" she flicked off the radio.
