Seito University Hospital, Operating Room
17:00
"We will now begin the surgery for resection of atrial extension giant cell carcinoma."
"""Please take care."""
"Vitals, blood pressure 105 over 68, heart rate 65. Commence extracorporeal circulation."
"Okay, scalpel."
After hearing the anesthesiologist's words and confirming that extracorporeal circulation had been started, Hiiro asked the nurse for a scalpel and started the surgery.
4 hours later, 21:00
Seito University Hospital, Basement
This is where the headquarters of the CR, a.k.a. the Cyber Rescue Center, is located, which is not open to the public. Hiiro, who had just finished the surgery and was transforming into Kamen Rider Brave, CR's best fighter, entered the secret facility.
"Ooh, Hiiro! Good job on the surgery!"
Asuna Karino, the DoReMiFa Beat Bugster, Poppy Pipopapo, came out of her living space, the DoReMiFa Beat game console, and greeted Hiiro after his surgery.
"Yeah, by the way, Poppy Pipopapo, have you heard anything about a Bugster appearing while I was gone?"
"There are no reports of Bugsters at the moment, nor are there any reports of game diseases!"
"I see, that's good to hear."
Then he took out a cake from the refrigerator and ate it, cutting it with a knife and fork as usual.
"Hiiro, don't eat too many sweets or you'll get sick."
"Sugar helps the brain to recover from fatigue, and you need to consume sugar after a surgery or any other brain-intensive work."
Then Hiiro started eating the cake again.
Beep, beep, beep
The stethoscope rang.
"Good grief, no time to rest?" He sighed, putting down the knife and fork and answering the call.
"This is the Cyber Rescue Center."
"Help me! My friend! My friend!"
"Calm down, tell me the place… okay, I'll be there, Poppy Pipopapo, there's an emergency at the nearby park, you can have this cake."
"Eh, wait!"
Hiiro told her abruptly and walked out of CR.
Park near the Seito University Hospital
"Where is the patient?"
As reported, Hiiro came to the park, but he couldn't find any game disease patients, so he looked around.
Then…
"You've been swindled, Prodigy."
There was an unfamiliar voice. Hiiro looked in the director of the voice and saw a man wearing a red jacket over a Hawaiian shirt.
"Who are you!?"
"I'm Kiriya Kujo, a medical examiner at Seito University Hospital, and I'm the one who called you earlier."
"Okay, so where's the patient?" Hiiro said, a little irritated.
"My bad, it's all a lie, there's actually no game disease patient."
"What the hell!? What are you doing!? Are you pranking me!?" Hiiro grabbed Kiriya by the chest and yelled.
"No, no, no, the game disease is a lie, but I do need your help, Prodigy."
"What do you mean?"
At Hiiro's question, Kiriya showed him something.
"That's Gamer Driver… and Bakusou Bike Gashat."
The thing that Kiriya was holding was the Gamer Driver, and two days ago, Masamune Zaizen, the president of the Genm Corporation, showed Hiiro one of his Rider Gashats, which is the Bakusou Bike.
"Actually, a stray devil has appeared in the neighboring Kuoh, and I would really like your help to cure it."
"What?"
When Hiiro heard what Kiriya had said, he let go of him for a moment.
"Surgery, huh… I don't mind, but did you get that Bakusou Bike from President Zaizen?"
"Yeah, he just gave it to me two days ago."
"This Gashat has the ability to separate the Evil Pieces, why ask me to do that when you can do it yourself?"
"You see, the thing is because my transformation."
With that, Kiriya buckled the Gamer Driver around his waist and activated the Gashat.
BAKUSOU BIKE!
"Henshin."
As soon as he inserted the Gashat, many panels appeared and he kicked one of them away.
Gashat! Let's game! Metcha game! Mutcha game! What's your name? I'm a Kamen Rider!
He then transformed into Kamen Rider Lazer Level 1, which had a different design than the Brave that Hiiro transformed into, but looked chunky.
And then…
"Second Gear."
Lazer pulled the Gamer Driver's lever.
Gachan! Level Up! Bakusou dokusou gekisou bousou! Bakusou Bike!
Lazer transformed into Kamen Rider Lazer Level 2, and at the same time, Hiiro understood why he was called.
"I see, so that's the problem."
To his surprise, Lazer was not humanoid, but in the form of a motorcycle.
"Get it now, Prodigy? So, why don't you ride with me to the race?"
"…Fine, I'll help you for the sake of the operation."
And with that, Hiiro put on a helmet and rode on Lazer's back to Kuoh.
Kuoh
It was just a coincidence that on this day, one of Rias Gremory's peerage members, who was in charge of Kuoh, was taking a walk outside because she was having trouble sleeping.
Then…
'What's that smell…'
She smelled a stray devil from an abandoned building she was passing. She immediately tried to contact her master, Rias, but just then…
"KYAAAAAAAAAAAA!"
Koneko acted before she could think, and went into the abandoned building alone without contacting Rias.
Inside the abandoned building
"Kekekekeke! Human! Food!"
"N-NOOOOOOOO! HEEEEEELP!"
In an abandoned building, a stray devil with thorns growing out of its body was trying to eat a woman it had lured with magic.
"DIE!"
The devil shot the thorns from its body at the woman being attacked.
"Watch out!"
Koneko pushed the woman out of the way just in time.
"T-thank you…"
"Please run away, quick…"
"R-right!"
With that, the woman left the scene.
"You bitch… you're interfering my meal…!"
The stray devil fired its thorns viciously at Koneko.
"…How troublesome."
She managed to avoid the attack, but since Koneko is a reincarnated Rook, attacks from a distance like this are not a good match. She pulled out a pillar of a nearby building.
"Blow away…"
Just when it thought it was over, she slammed the pillar into the stray devil.
"Not yet!"
The stray devil fired the longest, thinnest thorn from its body, and it pierces the pillar that Koneko threw at it.
"Uh oh… gah!" The thorn pierced Koneko's left side.
"HAHAHAHAHAHAHA! That's not nice, you know!"
The devil held the injured Koneko as if it was picking peanuts.
"Since you're interfering with my meal time, I'll eat you instead."
And then, when the stray devil was about to eat Koneko…
CRASH!
"What!?"
What a surprise, a motorcycle, Kamen Rider Lazer, came crashing through the window.
"Right, moving through, moving through, get out of the way!"
Then Lazer hit the stray devil and let go of Koneko with the impact.
"An injured… this is terrible."
Hiiro took off his helmet and rushed to the injured Koneko's side to check on her injuries.
"Examiner, call our hospital right now, tell them to send a helicopter, and get her to safety and give her first aid, I'll handle the operation." He said, throwing the first aid kit at the untransformed Kiriya.
"All right, well, take care of it, Prodigy."
With the first aid kit in hand, Kiriya carried Koneko on his back and hid in a safe place, while Hiiro pointed his stethoscope at the stray devil.
"Stage 2… made it just in time."
"Human… just in time, I'm going to eat you!"
"Well I don't want to get eaten… so I'm going for surgery."
TADDLE QUEST!
"Skill Level 1, henshin."
Gashat! Let's game! Metcha game! Mutcha game! What's your name? I'm a Kamen Rider!
"HAH!"
Hiiro transformed into Brave Level 1, and he held up his Gashacon Sword to fight the stray devil.
"Do you think you can defeat me with that bullshit!" The stray devil then fired many thorns at the oncoming Brave.
But…
"Sorry, but I don't see the point in that."
He then took out a coin and threw it right above him.
Steeling!
And Brave's body became as hard as steel, repelling all of the stray devil's attacks.
"What the hell!?"
The coin Brave had thrown was one of the energy items Masamune had sent him yesterday. Normally, energy items are randomly placed as soon as the level is started, but since that would not allow him to perform the surgery as he wish, Masamune used his management privileges to miniaturize some of the energy items and gave them to Hiiro so that he could use them whenever he wanted.
"All right, I'll speed up the surgery."
Speed Up!
He then used the speed-up energy item to attack the stray devil at an unbelievable speed.
"What the hell! I can't see him!"
The stray devil fired spikes at him, but all of them were dodged because they appeared to be stationary to the fast-moving Brave. And as a result of being slashed to pieces with the Gashacon Sword over and over again.
"GAAAAAAAAAAAAAAAHHHH!"
With an explosion, the former devil that was the base of the stray devil and the monster that fused with the Evil Piece and magic power separated.
"KSHAAAAAAAAA!"
"Okay, I'll finish it at once."
With that, Brave took the Gashat out of its holder and activated it.
DRAGO KNIGHT HUNTER! Z!
It was the new Gashat that Masamune had given him two days ago, the Drago Knight Hunter Z Gashat.
"Skill Level 5."
Gachan! Level Up! Taddle Quest~! A Gacha! Do-Do-Drago! Na-Na-Na-Kni~ght! Dra-! Dra-! Drago Knight Hunter! Z!
He then transformed into the Kamen Rider Brave Hunter Quest Gamer, a dragon-themed Brave with a sword-shaped weapon on his right arm, Drago Knight Blade, and the Drago Knight Gun on his left arm.
But then…
"Guh, shit!"
The Drago Knight Hunter Z is a Gashat that can go berserk if one mistake is made, and Brave was about to go out of control.
But…
"You… are a surgical tool… listen to me!"
At his shout, the signs of the berserk stopped. Hiiro's strong will as a doctor silenced it.
"Alright, let's go!"
With that, Hiiro charged towards the monster.
"KSHAAAAAAAAA!"
The monster then shot a large number of thorns at Brave, but he fired flames from the Drago Knight Fang, the "mouth" of the helmet, and burned all the thorns fired. He then quickly sniped the monster with the Drago Knight Gun on his left arm to suppress it, and when it was frightened, he jumped into the monster's opening and slashed it to death with the Drago Knight Blade on his right arm.
"Finisher."
Brave inserted the Drago Knight Hunter Gashat in the Kimewaza Slot Holder and pressed the button.
Gashat! Kimewaza! DRAGO KNIGHT CRITICAL STRIKE!
With a lot of energy gathered on the Drago Knight Blade…
"Haaaaaaaaah! HYAAAH!"
"GYAAAAAAAAAAAAAAAAAAAAA!"
He sent an energy slash at the monster, causing it to explode.
Kaishin no Ippatsu!
"Operation complete."
Then Hiiro pulled out the Gashat and untransformed.
"Prodigy, the helicopter is here!"
"All right! Examiner, get on the helicopter first."
Hiiro told Kiriya, who came to tell him of the helicopter, and got on the heli with the former devil he had just separated on his back.
"What about the emergency surgery!?"
"I've already contacted them to prepare." The paramedic on the helicopter said.
"All right, you've done the first aid… but it's bleeding badly… adrenaline shot."
"Yes."
Hiiro told them to inject Koneko with adrenaline.
"I…" The still faintly conscious Koneko muttered weakly.
"Don't worry, I'll save you." Hiiro said.
Seito University Hospital
"Let's get her on the stretcher, Examiner, give me a hand."
"Righto."
"Let's go, 1, 2, 3!"
As soon as he said that, they got together, put Koneko on the stretcher, and went straight to the operating room.
"That's terrible…"
"What the hell…"
The surgeons on duty were called in for an emergency operation, and when they got to the operating room, they found a girl with a hole in her stomach, puzzled as to what had happened.
"If you have time to be confused, get into position! This is a time-sensitive situation! We will now perform emergency repair surgery on the damaged organs, scalpel."
"Yes!"
"Loop."
"Excuse me."
Hiiro asked the nurse to lower the loop, grabbed the scalpel and started the surgery on Koneko.
Two days later
"Where is this…"
When Koneko woke up, the first thing she saw was an unfamiliar ceiling.
"Yo! You're finally awake…"
When Koneko looked in the direction of the voice, she saw Kiriya sitting in a chair.
