Around the time Fourze was fighting Salty and the others.

Seito University Hospital, CR Headquarters

"We've confirmed the spread of the Bugster Virus throughout Seito! A large number of game disease patients are appearing everywhere!"

"Director! We need more ambulances!"

"Calm down! We need ambulances from other hospitals as well! Even if we don't get ambulances, we can use trucks or anything! We need to get the patients to this hospital as soon as possible so they don't get caught up in the fighting!"

"Yes, sir!"

The CR was currently in turmoil as the game disease patients, Bugsters, and mysterious monsters had popped up one after another in various places.

"What a mess… if this keeps up, a lot of people are going to vanish! It's the Zero Day all over again!" Haima was screaming his head off at the sheer amount of damage.

"Perhaps the enemy's aim is to split our attention by creating disturbances throughout Seito…" Takatora analyzed the situation and saw that the enemy wanted to disperse their attention and then destroy them individually.

"But that doesn't mean we can't just ignore the infected, brother."

"You're right… it's unavoidable, we'll fall for the enemy's schemes… but human life comes first! Me and Ryoma are going to take down that Revol Bugster! Mitsuzane, you go for Salty! Minato and Sid will take on Motors! And Kiriya-sensei and other CR Riders… can I ask you for fighting Graphite?" Takatora said.

"Hmph, alright! I'll take care of Graphite!"

"As you wish! I will the one who will take care of Graphite."

"Well, if President Takatora gives the order, I'll just follow it."

"I agree."

"Heh, of course, Takatora, if I don't go with you, who will cover your back?"

"Okay, but be careful, brother."

Kiriya, Nico, Minato, Sid, Ryoma and Mitsuzane replied.

"Thank you, everyone… move out!"

Somewhere in Seito

"Commence the operation! Advance!"

"GUSHAAAAAAAAAAAA!"

A large number of Ant Lords created by Revol from Agito Gashat were currently making a mess here.

""Henshin!""

Melon Energy! Lock On! Soda! Melon Energy Arms!

Lemon Energy! Lock On! Soda! Lemon Energy Arms! Fight! Power! Fight! Power! Fight! Fight! Fight! Fight! Fi-Fi-Fi-Fi-Fight!

Takatora and Ryoma quickly used their Genesis Drivers to transform into Zangetsu Shin and Duke.

"Let's go! Ryoma!"

"Yeah, got it, Takatora!"

The two brandished their Sonic Arrows and charged into the hordes of Ant Lords and Revol.

In another place

"HAHHAAAAAAA! Let's get this show on the road! YEEE-HAAAW!"

"GUGYAAAAAA!"

"KSHAAAAAAA!"

Currently, this place was occupied by Motors as well as a swarm of Rat Fangires and a Spider Fangire spawned from the Kiva Gashat.

"Oh my… they've done a spectacular job…"

"Hah! I don't care what they do… henshin."

Cherry Energy! Lock On! Soda! Cherry Energy Arms!

"Let's get to work…"

"That's right, henshin!"

Peach Energy! Lock On! Soda! Peach Energy Arms!

"Here I come!"

"Yeah!"

Sigurd and Marika took their Sonic Arrows and charged into Motors and the others.

"You want to play with me!? Good! Let the race begin!"

Amanogawa High School, Gymnasium

"Are you alright!?"

"Calm down, you will be fine!"

"Ah, you just need to rest."

Currently, this place housed the Rider Club and a large number of game disease patients who were brought in along with other helpers.

"Miu! I've brought you some ice and energy drinks!"

"Thanks, Jun! Put some ice on his head."

"All right!"

Miu left the patient to Jun Shigeno, a member of the cheerleading squad, and went to check another person.

"Miu-senpai…"

"Yuki, how are you doing over there?"

"We managed, somehow… but there's no end to it."

"Right… but we're the Kamen Rider Club. That's why we have to do what we can." Miu murmured.

And then…

"W-what!? What happened here?"

"What, what? What is this noise!?"

"Sonoda-sensei, Ohsugi-sensei!"

Sarina Sonoda, the female teacher of Gentaro and co.'s class, and Chuta Ohsugi, a tall but bad-looking male teacher, heard the commotion and came to the gym.

"Sonoda-sensei, just in time! I'll explain but please help us!"

"Jojima-san? I don't understand what's going on, but… what should I do?"

"Yes, first…"

Yuki pulled Sonoda's arm and took her to a patient.

"H-hey! What's going on?"

"Ohsugi-sensei, you help us to!"

"Huh? WAAAAAH!"

Miu pushed him from the back and took him to the same patient.

Meanwhile

Electric!

Electric On!

"HYA! ORYAA!"

"Gah! Why you!"

"GUAAH!"

Kisaragi, who had transformed into Fourze Elek States, is fighting against Salty and Uva, while Power Dizer used by Shun is destroying many Waste Yummies. However, Fourze was struggling against the leveled-up Salty and Uva, although his powers were reduced to some extent.

"Two against one is tough, after all… but everyone's life is at stake! I can't afford to lose!"

"You little! Don't think you can beat me now that I've leveled up!"

"RAAAARGH!"

Salty and Uva shouted as they headed towards Fourze.

"Henshin!"

Budou! Lock On! Hai! Budou Arms! Ryu! Hou! Ha-Ha-Ha!

"HAAH!"

"WAAAGH!"

Ryugen fired at Salty and Uva before kicked them away.

"Y-you…" Fourze asked Ryugen who had suddenly appeared.

"I'll explain later, but for now, let's get him!"

"R-right! I don't know who are you, but thanks for the save!"

"Grrr! No matter how many people are here, I'll salt you all!" Salty yelled, and together with Uva, he began to attack.

Yet another place

Kiriya and Nico had come to the commercial area near Seito where Graphite was located.

"There you are, Riders!" Graphite, who didn't run or hide, said.

"Graphite! Prepare yourself!"

"That's right! We'll take you down and end all of this bullshit!"

"Heh, all right, come on, Kamen Riders! Let's settle this today!"

DRAGO KNIGHT HUNTER! Z!

"Cultivate."

With that, Graphite activated the Proto Gashat and transformed into Dark Graphite.

"Bring it on!"

BANG BANG SHOOTING! JET COMBAT!

"Tactics Level 3! Henshin!"

Gashat! Gachan! Level Up! Ba-Ba-Bang! Bang-Ba-Bang! Yow! Bang Bang Shooting! A Gacha! Jet! Jet! In the sky! Jet! Jet! Jet Comba~t!

"Mission start!"

"Me too! Let's get started!"

BAKUSOU BIKE! GIRI GIRI CHAMBARA!

"Gear blast, henshin!"

Gashat! Gachan! Level Up! A Gacha! Giri-Giri-Bari-Bari Chambara!

Following Nico's transformation into Snipe Combat Gamer, Kiriya transformed into Lazer Turbo Proto Bike Chambara Gamer.

"Interesting… come!"

"HEAAAAAAAAAAAA!"

"ORYAAAAAAAAAA!"
