I don't own My Hero Academia or Kamen Rider and they belong to their respected owners.

The Pro-Heroes in Musutafu were outside the light barrier created by Kamen Rider Calibur. They tried to go in but couldn't. Only the wielder of the Seikens, holy swords wielded by chosen individuals and to use Wonder Ride Books, small devices that have the power of God Beast, Animals, and Stories. The hero community didn't really understood it till they were probably explained by Todoroki Shouto and Todoroki Fuyumi, the son and daughter of the #2 Hero Endeavor.

Shouto Todoroki was raised to be a hero but gave up on that dream to be a writer, much to the disappointment of his father but still became a hero by becoming Kamen Rider Saber. Fuyumi became an editor to help her brother fulfill his dream. The Hero Public Safety Commission didn't have a choice but to let the swordsmen handle Calibur and the Megid.

"Are sure there isn't anything we can do?" Fatgum asked.

"No, we all tried to enter and break the light barrier but to no anvil." Best Jeanist replied.

"What did swordsmen say if they fell?" Hawks asked.

"That our world will connect to another world and the villains will try to gain more power." Gang Orca explained.

"Damn, this is way out of pay grade." Mr. Brave commented.

"You're right this is beyond the typical criminals like the League of Villains. But I'm sure those swordsmen can stop this, they haven't failed before." Best Jeanist agreed before turning to Endeavor. "Don't you think so as well, Endeavor?!"

Endeavor ignored Best Jeanist and stared at the light barrier knowing there's nothing he can do about it. Fuyumi tried to reassure him and to trust Shouto but Endeavor still had doubts. He was furious when Shouto gave up on being a hero so can be a writer. It frustrated him. Now look at Shoto becoming a vigilante, even with the Hero Public Safety Commission, Shoto and his allies are still breaking the law, but as before there's nothing he can do about it.

Suddenly a figure in white and gold rushed past the heroes and straight to the barrier. The Heroes saw it was Espada, they were told he was injured and was resting, then what was he doing here.

"I thought that kid was on medical leave?!" Fatgum exclaimed.

"I guess he's better." Hawks commented.

"Then I hope with him they added more strength." Best Jeanist said.

"Now, all will be complete," Daichi says as he draws power into his sword with dark purple energy.

"Noooo!" Shouto shouted as he charged towards Calibur.

Shouto tried to cut down Calibur but was blocked and was slashed back by the latter.

"Novelist!" Ryo cried out.

Then a Goblin Megid caught their attention when charged forward to attack the wounded Blades.

Jaou Hittasu!

Calibur then sends a purple slash at Blades. As the Megid was about to hit Blades, Epada appeared to block the Goblin and use it as a shield for Calibur's attack slash but the slash destroyed through the Goblin Megid with Espada trying to block the attack but it was no use Espada was still hit by the attack.

"Kento!" Rintaro shouted.

"Kento!" Shouto cried out.

"Kento!" Shouted Ryo.

"Kento-kun!" Ren shouted as well.

Espada de-henshin as he fell down to his knees.

"Kento!" Souto and the others ran to his side.

While the Riders were at their friend's side, Calibur was gathering energy from his sword and Ride Book then the energy created a purple pillar of energy.

~/~

"Great another one." Hawks said sarcastically.

The heroes saw the pillar of energy rise from inside the barrier. Before they could discuss anymore the Kamen Riders were thrown out of the pillar as Blades de-henshin.

"Hey, what happened in there?!" Death Arms shouted.

They ignored him as Rintaro spoke up.

"Kento, why did you do that?!" The Mizu no Kenshi questioned him.

"Because we're family. It's only natural." Kento answered. "More importantly…"

"We know! We'll carry out our mission!" Rintaro shouted as he bowed his head. "And we will definitely save you."

"Sounds like you're letting personal feelings bias you," Kento says with a hint of a smile.

"Of course… after all, we're Homo-Sapiens!" Rintaro retorted back.

"Who calls themselves Homo-Sapiens? Can't he just say, humans?" Hawks whispered only to be elbowed by Fatgum.

Everybody heard a new person running towards them, it happens to be Fuyumi.

"There you are Kento! And I thought Natsuo was reckless!" Fuyumi exclaimed as she ran towards them.

"Fuyumi what are you doing here?" Endeavor questioned her.

"Kento escaped while I wasn't looking and knew he would be here." She told her father.

"Ahhh!" Screams were heard as heroes went flying by purple energy. They saw Calibur there looking up at the sky.

"Fuyumi-san!" Rintaro getting her attention. "Please take care of Kento!" As he and the others started to get up. "Endeavor-san, can you watch over them, please?"

Endeavor stayed silent before finally nodded as he watched Rintaro henshin back into Blades and he, his son, and the other charged forward Calibur.

"At last the door will open," Daichi says, he hears grunts as he turns around to the other swordsmen.

Calibur fought the Sword of Logos members, easily handling them with their 4v1 advantage. Soon a large white book floated above everyone.

"That's the door to the truth!" Shoto gasps before being kicked by Calibur.

The three other swordsmen charged at him but not before Calibur span with purple energy slash.

"You're in the way!" Daichi shouted as he made everyone except Shouto de-henshin.

Saber looks around to see his friend beaten.

"I will…" Saber enters his Seiken into his Driver.

Hittasu!

He charges forward as pulls out his sword from his driver.

Rekka Battou!

Saber tried to strike Calibur down with a fiery slash but the latter dodged his strike and started his finisher.

Kurayami Iai! Shutoku Issen!

Calibur slashed at Saber sending him far back.

"You can't protect anything with the little power you possess," Daichi told him.

"Shouto!" Fuyumi cried out knowing Kento had little time.

Shouto couldn't fail Kento, not like he failed Luna.

"No!" Shouto grunted as reached for his sword. "I won't fail to protect this time!"

"Shouto can do it…" Kento struggled to say. "I believe in him."

"I want to save this city and Kento!" Shouto stands back up.

Rekka Battou and the Brave Dragon Wonder Ride Book started to glow. Suddenly, a small portion of the sky changed showing the Aurora.

"What the hell is going on?" Hawks asked out loud.

"The boy's strength is rising up." Endeavor simply says.

An orange light floated to Shouto as he looked on to it.

"That is…" Daichi is surprised at what's happening.

"That book from that time…" Shouto commented.

"Shouto, you have the power." Said a young girl.

"Luna... Luna!" Kento was surprised to hear her voice.

"Luna?" Shouto smiles before reaching out to grab the new Wonder Ride Book.

He looks at it to see the title Dragonic Knight. Everyone can see this book was a bit bulkier than others they'd seen.

DRAGONIC KNIGHT!

Shouto then opens the book.

Dodekai Ryu O Dohade Ni Norikonasu Dokyuu No Kishi No Dramatic Battle...

He placed the Ride Book into the right slot before drawing out Kaenken from his Swordriver.

Rekka Battou!

A large version of Dragonic Knight as Kaenken's blade was engulfed in flames and Brave Dragon was flying around him.

"Henshin!" Shouto shouted.

Don't miss it! (The Knight Appears. When you side,) DO-METALLIC ARMOR!

Flying metal armor flew around Shouto as he performed two slashes in the form of an 'X' before sending it forward. The metal armor attached itself to Shouto creating his new form.

(You Have No Grief And The Flame Is Bright) DO-HADENIKKU BOOSTER!

The slashes returned forming the visor, completing the transformation as flames danced around him.

(Ride on Dragon, Fight.) DO-HAKURYOKU RIDER! (Dragonic Knight.) DRAGONIC KNIGHT! Sunawachi do Tsuyoi!

With the black bodysuit, he wore a silver breastplate with shoulder guards that had red outlines. He had silver arm guards with a red gauntlet with a dragon similar to Brave Dragon on his left arm. He had silver poleyns and greaves on his legs and silver sabaton on his feet. There was a silver skirt with red markings that was attached to his waist. He had a silver knight-like helmet with a large red X visor and spikes on the side of his helmet. This is Kamen Rider Saber Dragonic Knight!

"Woah…" Mikuro muttered in awe.

The female reporter and her cameraman were also in awe but the reporter gained her composer back.

"Focus! Keep rolling!" She told her cameraman.

Cameran stopped his awing and pointed the camera at Saber.

"So you obtained new power?" Daichi huffed. "It matter not!" Calibur slashes a purple slash at Saber.

The energy slash could have made contact but the flames caught it and sent it back to Calibur.

"Nani?!" Daichi exclaimed as he blocked the counterattack.

"You said comrades are not needed," Shouto says.

Both dragon Riders walk towards each other, Calibur makes the first move, slashing at Saber's chest. The slashes sent out sparks but Saber did not flinch; he kept moving forward making Calibur walk back.

Saber then blocked the attack before pushing Calibur back and sending flames in front of him sending the latter stumbling back.

"But I can fight because I have comrades who believe in me!" Shouto exclaimed.

"Gooo, Novelist!" Ryo cheered.

"Go!" "Gooo!" "Goo!" Ren, Rintaro, and Fuyumi started cheering as well.

~/~

Elsewhere in a psych ward, a white hair middle-aged woman was watching the news on Saber fighting off the Dark Rider with his new powers. Shouto's mother, Rei.

"Go, Shouto. I know you can do this." Rei muttered praying for her son's victory.

~/~

In the headquarters of the League of Villains, the villains were watching the sword-wielding hero fight off Calibur.

"As much as I hate heroes, I hope this Saber beat this purple dragon guy," Tomura says. "The least I want is to live in some fairy tale land."

"Oooh, do you think they have princesses and fairies in there?!" Twice commented.

The scared villain Dabi just watched Saber and only let out a 'tch'.

~/~

Hearing his friend's encouragement, Saber's right hand begins to glow.

Dragonic Booster!

Saber holds a tight grip onto the gauntlet's Booster Grip.

SPICY!

Saber delivers a fire-enhanced punch that blocks Calibur's attacks.

"You said you gave up everything, but…" Saber opens his gauntlet's mouth.

Dragonic Booster!

"…having something to protect makes you want to make you stronger!" Saber scans the Brave Dragon Wonder Ride Book in the Dragonic Booster's jaw.

One Reading! Brave Dragon!

Saber readies himself until he pressed the Booster Trigger.

FLAME SPICY!

Saber then blasts a concentrated stream of fire from the Dragonic Booster at Calibur. Calibur struggled to block the attack but was overwhelmed and was thrown back.

Dragonic Booster!

As Saber stood tall, nobody noticed the hooded man by the tree watching Saber.

"The strength of our feelings becomes our power!" Shouto says.

Calibur started to get back up. "It's too late. Very soon I will enter the almighty truth." He says as he turns into a ball of purple energy.

"He's trying to escape!" Miruko shouted.

"No, he won't!" Saber taps on his Ride book three times.

The large version Dragonic Ride Book appeared behind Saber as a fiery red dragon came out of it.

The Knight Appears. When You Side, You Have No Grief And The Flame Is Bright. Ride On Dragon, Fight. Dragonic Knight~.

Saber jumped up and landed on top of Brave Dragon as they followed Calibur as the Heroes looked at him in awe and Fuyumi and other Riders grinned at him.

Brave Dragon flew, getting Saber close to the ball of purple energy, and struck it. He got a distance away as Brave Dragon fired a fireball at the Calibur.

"You will see someday…" Calibur returned back to his physical form. "To obtain something, you have to make sacrifices."

Saber didn't retort back and started striking Calibur, making the latter take numeral damages. Now both dragon Riders were a few feet away they both started their finishers.

Jaou Hissatsu Dokuha!

"I will decide how this story ends!" Shouto declared.

Dragonic Hissatsu Dokuha! Rekka Battou!

Both Riders charged at each other as both of them were enveloped with their respective energy as they clashed swords.

Jaou Hissatsu Geki!

Dragonic Hissatsu Giri!

"Rekka Ryuuhazan!" Shouto announced as he was able to give a supercharged, fire-enhanced slash through Calibur.

"Gahhhh!" Daichi screamed as he exploded with Ankokuken Kurayami falling to the ground.

Saber then had Brave Dragon fire a fireball at a large blank Wonder Ride Book covered with energy hoping to stop it from doing anything else. At least for now.

~/~

Shouto ran to where everyone was as he saw everyone surrounded Kento as he released dark energy from his body.

"Kento!" Shouto ran to his side. "Kento…"

"Shouto…" Kento whispered. "It's alright."

"Kento. Luna is alive!" Shotuo exclaimed.

"Yes. I heard her too." Kento weakly nodded.

"You said the three of us will always be together!" Shouto whimpered. "I failed to save another…"

"No… you saved me, Shouto," Kento reassures his childhood friend. "Not just you… but everyone… saved me… saved my soul."

As Kento weakly talks with friends surrounded by him, the Pro-Heroes can only watch this goodbye. They learn the darkness from Fuyumi was hit by the darkness that will soon consume him. They can tell Shouto tried so hard to save the city and his friend even with gaining a new form it wasn't enough.

"Kento!" Shouto cried.

"I wish… I could continue to fight with you all." Tears fell from Kento. "Thank you for everything. For doing this for someone like me." Kento looks at Shouto. "Please… protect this world… protect this world we live in." Shouto grabbed his hand. "…with everyone."

"I promise you," Shouto reassures him even the tears coming out of his eyes.

"Leave it to me!" Ryo shouted.

Ren could only cry while Tetsuo held back his tears and nodded to Kento.

"Of course!" Rintaro exclaimed.

"I promise you too," Fuyumi said as well.

"We all will." Join in Endeavor and get nods from the other Pros.

Kento could only smile as the darkness engulfed leaving him in pain. Everyone went to his side calling his name.

Shouto held him in his arms calling out his name.

"Shouto! Shouto!" Kento cries out as his eyes open with his eyes turning red.

"Kento!" Shouto called out to him one more time before Kento fully disappeared into a dark miasma leaving nothing but the broken hearts of everyone around him.

AN: Here you go guys, I thought of this the other day and wrote. I wanted to upload a Fairy Tail/Oma Zi-O one-shot but I'm still struggling with that one. You might be surprised with me making Shouto the Protagonist instead of Izuku. I thought Shouto was more suited for it and with giving his origins a bit of change I made Shouto into Saber and made him upgrade into Dragonic Knight. I let the other Saber Riders stay the same because it felt right.
