The ending of Massacre differs from the anime to the manga –I don't know about the games. This is the manga version, wherein time briefly freezes while the bullet is headed towards Keiichi, and they all have their conversation about him being out and them having to run away within that time-bubble, before the bullet hits him. The rest of them are then grabbed and killed execution-style in the road, minus Rika, rather than making sacrifices of themselves one by one so the others can get away.

"Hanyuu. You're still resigned to my fate as usual, aren't you?" Rika asked as she and her friends charged through the grass and the woods, towards the Wild Dogs' van.

Hanyuu, drifting along beside her as she ran, was grave and silent, her face trouble.

"Heh. Are you watching?" Rika scoffed, looking ahead as she plowed forward with the others. "I'm going to tear down my destiny. And I'm going to do it right where you can see!"

She'd never felt so alive as she charged through the forest with her friends, feeling like she could run forever, could outrun anything, could do anything, just as long as they were at her side. Destiny? Fate? Laughable! They'd already overturned her fate of dying tonight, and they had a plan, a brilliant plan, a solid, workable plan, and there was nothing but more of those thugs that they'd already beaten between them and victory!

And then suddenly, everything changed.

Mid-stride, mid-step, Rika froze. The sound around her froze. The world froze, colors going just a little strange in ways she couldn't describe, like she viewed them through a glass warped in ways she couldn't understand, or through an oily film she couldn't quite see. And she wasn't the only one –everyone else in the club had stopped, Satoko running beside her with determination and frozen mid-grin, Keiichi just ahead of her and on her other side, Mion and Shion in the lead and Rena bridging the gap between them and Keiichi.

"Rika." Hanyuu said softly, appearing before Satoko and pointing outwards, across Rika's body. "The time has come."

Eh?

Rika blinked at her outstretched finger, and followed it, looking, and at first she couldn't see anything. It was dark, and the moonlight didn't seem quite right, didn't seem like it had been these past few minutes, before all the world froze. So it took her a moment or two to search, but when she saw what Hanyuu was pointing to, her blood froze.

"K…Keiichi…that thing floating in front of your chest…what is it?" she croaked, cold sweat pouring down her face.

Keiichi blinked, glancing aside to her, apparently unperturbed by the sudden freeze in time, the way that he couldn't really move aside from his eyes and a little bit of his head.

"Huh? What's what?" he asked, and then looked down.

Everyone looked.

Everyone saw.

"Huh?" Keiichi gulped. "What…is that?"

But he knew. They all knew. They'd all seen the cartoons, the comics, the TV shows. They all knew what a bullet looked like, even though this one was hanging in midair, still smoking, but with the smoke frozen like a fountain of air inside ice. The bullet was still, but it was there, and it was so, so close.

"Why is that bullet floating…?" Shion managed, her face ashen.

"Has time stopped?" Mion asked, her eyes flicking busily around them even when she could only move her head a little, so very little. "Is that why?"

"No…" Rena whispered. "But that's…"

"So when time starts moving again, Keiichi-san will…" Satoko gulped, realizing the same thing that Rena had. "Keiichi-san will die!"

"B-but who shot it?!" Keiichi asked, staring down at the bullet less than a foot from his chest.

"Those guys are behind us." Rena agreed. "So why…?"

"Look over there!" Satoko gasped. "It came from the van!"

"It was Takano-san!" Rena cried, seeing the caped figure standing there with a pistol outstretched. "She shot Keiichi-kun!"

"K-Kei-chan!" Shion stammered. "Can you twist around somehow and dodge the bullet?!"

"Don't be stupid!" Keiichi shouted at her, displaying a rare flash of temper as more sweat stood out on his face. "How am I supposed to move when everything's stopped!?"

"So if you can twist your chest to the right when time starts again…" Satoko tried, licking her lips and trying to apply every scrap of knowledge she had.

"Its like six inches away." Keiichi said, a flatness coming over his voice now, an acceptance. "There's no way."

"Th-there has to be a way!" Mion blurted.

"Don't give up, Kei-chan!" Her sister agreed.

"Keiichi…" Rika said.

I don't know what to do. How can we save Keiichi from certain death?

The silence and the knowledge of that loomed over all their heads, until Keiichi broke it with a shaky laugh.

"It's over." he said. "There's nothing I can do now. When time starts moving again, I'm going to die. So guys…just give up on me. Takano-san's right there. Take her down, and take the car. Don't think about anything else."

Rika's ears rang. He couldn't possibly be speaking such lies, such blasphemy. This was Keiichi, the liveliest of them all, the passion of their club, the man who could light a fire within all of them. This was her perfect world, a place where no matter what she had to struggle through, there was always a way for the dice to come up sixes again. There had to be a way to save him!

She couldn't think of one. None of them could.

"No. We can't let you die, Keiichi!" she burst out anyways. "I don't want a world like that!"

"She's right!" Mion choked. "You can't just die on us! I don't believe it!"

Rena gritted her teeth.

"Stop it, Mi-chan. We have to focus on beating the enemy in front of us." she ground out. "We have to go! That's what Keiichi-kun wants!"

"Yeah, that's right, Rena." Keiichi breathed, a smile drifting across his face for a moment. "Guys, take care of Rika-chan for me. Then get out of here and call Coach Irie. They've probably already killed Oishi-san. That's why he never showed up."

Rika shook, unable to deny this, unable to fix this, everyone staring with grief and with horror at the path ahead, the path that would take them onto the future and leave Keiichi behind, as he took a deep breath and shouted out one last bit of inspiration, one last push for his friends.

"I may be about to die, but I want you all to keep living! No matter what!"

"Hanyuu!" Rika hissed to the one that only she could see, holding her tears back as frustration rose in their place, frustration and desperation and all the things that she had ever felt trapped in this maze, condensed into one moment of utter despair. "Is this destiny?! Is this my unavoidable fate!?"

"It's all right, Rika." Hanyuu murmured, sounding as mournful as she ever had as Rika grit her teeth. "You can forget. You can forget all about this."

"Rika-chan." Keiichi glanced towards her, and the acceptance in his eyes was more terrible even than despair. "Sorry to do this to you at the last second. After all my big talk about overturning destiny…I'm the first one out."

"KEIICHI!" she screamed, the tears spilling over, the despair spilling over, and off in the distance, Takano chuckled.

"I see you've finally finished watching your life flash before your eyes." she sneered, her smile curling her face up like a demon's mask as the sound of a gunshot, belatedly, reached them all.

Keiichi lurched back.

The rest of them kept running forward.

And they still didn't make it.
