I don't own Akame ga Kill! or Kamen Rider and they belong to their respected owners.

Darkroachi were everywhere, the capital was completely overrun with them. It seems like it was the end of humanity as we know it. But there are some individuals who kept on fighting hoping to stop this apocalypse.

"Tatsumi, you don't have to do this!" Akame exclaimed.

"I have to, it's my responsibility as Blade," Tatsumi said.

"Akame is right, you don't have to Tatsumi," Najenda said with what was left of Night Raid nodding.

"Wave is out there and he needs my help. He didn't ask to be the Joker Undead, and with all fifty-two Undead sealed, he is the winner of the Battle Fight," Tatsumi said.

"Are you going to seal him?" a female voice said.

Night Raid turns around to Kurome and Run. The Assassins were on their guard thinking this was their way of using the chaos to kill them.

"Hey, hey, we're not here to fight," Run said. "We heard about Wave and we want to know if you're going to seal him in a Rouze Card."

"I-I don't know…" Tatsumi said, looking unsure himself.

"You are going to save him, right?" Kurome looks at him.

"…" Tatsumi showed a sad frown. "I don't know." Next thing he knew, Kurome at her Teigu, Yatsufusa at his neck.

"Kurome!" Run and Akame called out, while the rest of Night Raid ready their Teigu to attack. Akame was about to pull her Teigu, Murasame, but she heard sniffles coming from her little sister.

"P-Please… y-you have… to s-save him," Kurome pleaded as she lowered her blade.

Tatsumi grabs both her shoulders and looks at her straight in her eyes with a determined look.

"Don't worry I will save him and you'll have Wave back," Tatsumi told her as she walked out their base which feels like it would be the last time. As he made it outside he heard footsteps behind him. He saw Akame and Mine behind him. "You can't follow me, I have to do this alone," Tatsumi told them.

Akame only answered by giving him a small peck on the lips then hugging him, "Don't die."

Tatsumi and Mine were surprised by what she did, making the latter pull Akame away from the Rider.

"I don't know why you had to kiss my boyfriend! A peck on the cheek would've been fine!" Mine exclaimed as she grabbed hold of Tatsumi's collar and pulled him into a hard kiss. "But she's right don't die, please."

"I won't die, I promise," Tatsumi smiled as he pulled in Mine and gave both her and Akame a hug.

They were having their moment till they heard Leon breaking the mood, "If we're giving affection to Tatsumi I want to give him a big smooch as well."

Mine gets out of the hug and blocks Leon's path because she knows that with Leon teasing she could give Tatsumi a kiss he won't ever forget.

"No, you won't!" Mine shouted.

"Aww, come' on Mine," Leon whined.

Tatsumi could only laugh at his friends no, his family interaction.

"Stay safe everyone," Tatsumi said as he walked away from that, took him in, and treated him like family.

Esdeath for the first time felt weak. No matter how many she kills, these Darkroachi keep coming in larger numbers. She has to end by the source and that would be Wave the last Undead, the Joker.

"Wave, your death will be by my hands!" Esdeath shouted as she ran towards the green monster.

She then uses her Teigu technique: Weiss Schnabel on Wave and the Darkroachi in front of him. As she released many icicles destroying all the Darkroachi and some the icicles struck Wave making him leak green blood.

The ice shards pop out of his body and with his wounds quickly healing themselves. Esdeath growled and tried to give out another attack but more Darkroachi appeared and started attacking her. They just keep coming and Esdeath feels like she will finally be overrun. A Darkroachi was going to strike her from behind but it was sliced in half by Tatsumi.

"Tatsumi?" Esdeath looked surprised to see him.

"Leave," Tatsumi said.

"Excuse me?" She wonders if she heard him right.

"Leave the capital and never come back," Tatsumi says.

"You have guts to say that to me," Esdeath smiled.

"I'm going to face Wave and whoever wins we're going to kill you," Tatsumi said. "My King Form is more powerful than your Teigu and if Wave wins the roaches would soon overrun everything and all humans will die. So I'm giving you a choice to leave or die by one of our hands."

"Tch," Esdeath sneered. "Do you really think you can kill me?"

"Yes, no more innocents will suffer the pain you put them through," Tatsumi says. "I will protect the weak."

"You're a fool!" Esdeath growled.

"No, I am a Kamen Rider, the guardian of the innocent which you are not. Now get out of here before I let Darkroachi tear you apart," Tatsumi says as he walks towards Wave's location.

Esdeath could only look at him for a few seconds before walking in the other direction.

As Tatsumi made his way to Wave he saw the Joker back in his human form.

"Tatsumi?" Wave looks at him.

"I'm here to stop this, Wave," Tatsumi said.

"So you're here to seal me right?" Wave said.

"No! I'm here to help you, to bring you back to Kurome," Tatsumi said.

"You know I can't! The only way to save them is for you to seal me, please Tatsumi," Wave pleaded.

"I-I can't…" Tatsumi's face filled with regret.

"Then you have no choice," Wave said, as he brought out his Mantis Rouze Card.

Tatsumi brought out his Blay Buckle and inserted his Change Beetle into his Driver. He then places the Buckle on his waist and creates a belt over his waist.

Tatsumi and Wave look at each other and in their minds and hearts, they want nothing but to save the people they care about.

"Henshin!" They both shouted.

TURN UP!

CHANGE!

The two charged each other and activated their Drivers transforming them into their armors. The Riders charged at each other with their respected weapons out and started slashing each other releasing sparks from their chest.

Kamen Rider Blade. Kamen Rider Chalice. Two Riders who fated to face each other in the final battle. This is not the only world where they're fated to meet each other but in many Worlds of Blade.
