『A local human disaster alert has been issued!　The team in charge of the area should rush to the site immediately!』

In Jimbocho, where reconstruction was in progress, the rebuilding of the Hero Headquarters building had been proceeding at a rapid pace and the new building was scheduled to be completed in April. The men received an urgent message just as they were making a preliminary inspection of the new building.

「Roger that, Location?」

『Currently moving towards Ginza while turning Kasumigaseki into ashes! The area around Tokyo Station has not been evacuated yet, so don’t go near it!』

「……I’m trying. Tokyo people don’t know how to relax.」

「They must have eaten too much spicy soup to make ‘em so salty.」

They are the “Prodigal Sentai Dotsuitaranger” which is the name of the Osaka branch of the National Public Safety Commission’s Special Task Force for Local Human Disasters. Normally, they are based in Shinsaibashi, Osaka, but they were temporarily transferred to the Tokyo Headquarters to fill the personnel vacancy caused by the repeated devastation of the Kanto Hero Headquarters.

The five warriors boarded a special vehicle, which would normally be stored at the bottom of the Dotonbori River, and headed for Ginza on their way. When they arrived at the scene, they didn’t even have to look for the mysterious being before they saw a huge pillar of fire rising in front of us. A female-like figure in the center notices the existence of the Dotsuita Rangers.

「…………」

「Ooh, yer’ doing things with such flair. ‘Tis the time to score some points.」

「We’ve gotta show ‘em that we are on a different level than Tokyo people.」

「Don’t let yer’ guard down! Tsukkomi Change!」

The man in the leadership position held his right hand up like a sword, and the other four followed suit. Then the five formed a circle and slammed the back of their right hand against each other’s shoulder.

「「「「「Nandeyanen (Why the heck)!」」」」」

The bodies of the five glowed in five different colors and transformed into hero suits. The absolute guardian gods of Osaka, symbols of awe for the Kansai mysterious beings, descended upon the land of Tokyo.

「Takopin One-Shot! Takoyaki Red！」

「“Utsushimoyu”」

「「「「「Guwaaaaaaaaah!!!!」」」」」

The jet-black flames and shockwave sent the Prodigal Sentai Dotsuitaranger flying off in a parabolic arc like a golf ball. They flew through the Ginza sky, passed the former site of the Tsukiji market, and fell chap into the Sumida River accompanied by ‘chyapopopopo’ sound, about a kilometer away.

…………

The man who was monitoring the situation at the hero’s temporary headquarters in Asagaya roared to the sky.

「Uwooooooooooooooooh!! What a flame! My identity!! My characteristics are getting weaker again!!!」

His name is Kurenai Retto, a hot-blooded man who has just returned to work as the leader of Victory Sentai Victoranger. He was wearing short sleeves at the end of February, when the cold weather was finally starting to ease up. In fact, his brown skin peeking through the bandages wrapped around his body was slightly sweaty.

「Asaka-san, please! Please let me be dispatched!」

「I cannot approve it. Because Kurenai-san is the only Victoranger currently.」

Yes, it was good that he had returned, but Retto was the only one in Victoranger currently.

Green, who died in the line of duty without being seen.

Black, who turned into a mysterious being and disappeared.

Blue, who was recovered from the scrapyard but was still being repaired.

Yellow, who has gained so much muscle that he could no longer get out of bed.

Pink, who had been on leave since last week, saying she had an important memorial service to attend.

By the way, Will and Lamar, who were additional members, resigned from their jobs and joined a comedy training school in Kansai.

The only ones left were Red, Retto, who was rescued last week in the tsunami of swords weighing hundreds of thousands of tons.

「Kurenai-san, who had been forced to fast for more than a week, is also in no condition to go to the front line.」

「It’d be fine if it’s me. I am already very excited!」

「It’s a mystery why you can be so excited……」

Over the past week, hero teams in the Kanto region have been attacked and destroyed one after another. Retto’s frsutation had reached its peak as the damage continued to mount. Even Commander Asaka was frustrated because there was nothing she could do, the Hero Headquarters has not yet been able to capture even a glimpse of the elusive mysterious being.

「The enemy is very skilled. There is no guarantee that Kurenai-san will be able to handle them.」

「Asaka-san, I can see it. Their movements are clearly different from before… don’t you think they are in a hurry?」

「Is that intuition?」

「It’s intuition!!」

At that moment, the image on the monitor showing the situation in Ginza was disturbed. The operator’s voice echoed from a radio attached to the monitor.

『Drone succeeded in taking close-up photos of the mysterious being!　Footage from the scene is sent!』

The image of a serial hero attacker, and a black flame mysterious being that instantly slaughtered a team on loan from Kansai, was shown on the monitor.

As soon as Retto and Asaka saw her, they involuntarily looked at each other. The woman with long flaxen hair, a healthy physique, and wearing small pajamas that looked as if they were about to be ripped off was….

「This is…… Asaka-san……? She seems strangely familiar……」

「……Saya……?」

Asaka unintentionally mentioned the name of her sister, who awakened as a mysterious being three years ago and left her.

…………

「Well then, let me explain.」

After instructing the zako fighters to clean up the burnt-out venue and plug the gaping hole to the ground, Rintaro and his group moved to the Dark Assembly Hall.

Rintaro was accompanied by Kirika and Minato as his deputies.

The others were Leader Dragius III, who had been treated for his wounds, and General Tagaraak, who had pulled a nine-year-old version of Kurara out of storage and had grown a little younger.

Also present were the executives with their respective deputies, General Bearion and General Zazoma.

Not only that. Outside the Assembly hall, the entire Ark Dominion army was already assembled, fully armed.

「Gahahahahaha!　You’re alive after all, Tagaraak!　Just as I thought!」

「O ye who go by the way in the mist, and hear the voice of the stars! The gods who stand by and watch, do they point towards glory? Or is it destruction? It is not God’s will that your footsteps set forth. Let your hearts follow the compass, and lay your hands on the veil of truth. Then the way will be shown to you.」

「Zazoma-sama said, “Oya Oya, who was ther person that was crying at the vigil? Is the bear’s funeral next?”.」

「I was not crying!　I just had a little too much to drink!」

Bearion was baring his fangs in anger, and Zazoma was acting at his own pace as usual, but when Dragius let out a cough, they immediately shut their mouth and looked serious. Dragius began to speak slowly in a voice that sounded like it was coming from the depths of the earth.

「This is an emergency situation, and I want everyone to listen with an open mind.」

Dragius swept his keen eyes over the faces of those in the Assembly Hall, then took a breath and continued speaking.

「Hinosmera, the Purgatory Mysterious being, has returned. It was, too, through the medium of Samecchi’s body.」

At Dragius’ words, Tagaraak closed her eyes and crossed her arms with a grim look on her face. The others, however, did not seem to have quite grasped the situation.

「Hinosmera? What is that?」

「It is no wonder that you do not know about him. It has been 10 years since we sealed her up, so there are very few people in the Ark Dominion who knows about him.」

Ten years ago, it was surprisingly Rintaro, the newest member of the group, who reacted the most to those words.

Most mysterious being organizations were always targeted by heroes and were usually destroyed within about a year, which is an extremely fast cycle. However, Rintaro had knowledge of past mysterious being incidents that he had learned as a hero.

Rintaro exchanged a few words with Kirika, another Hero School graduate.

「……If it’s 10 years ago…… Mayuzumi, it’s that.」

「Black flame… No way. Damn it, I should have noticed sooner.」

「……Umu, as expected of Rintaro, did you already guess?」

In response to Dragius’ question, Rintaro nodded silently.

Just ten years ago, a mysterious being attack caused extensive damage to the entire Kanto region. Perhaps reminded by the exchange between Rintaro and his deputy, the other executives and deputies forgot about humiliating each other and became serious.

「I see, 10 years ago… damn, so that’s what you meant…!」

「Do not speak of love under the moon, for the arrows of jealousy will pierce even the bonds of Hiei Renri. I am the one who conquers the abyss in the depths. I am the hermit who picks up the divided wings and spins the raw silk.」

「Master Zazoma says, “It is the unforgettable calamity of Fuji”.」

Bearion clawed at the hard desk, and even Zazoma stopped to drink his tea.

All Japanese know the calamity of Fuji, which is probably deeply etched in their memories even if they are not mysterious beings.

A catastrophic local human disaster that turned the five lakes of Fuji into one lake. The mysterious being that was blamed for the disaster was Dragius III, who was standing right in front of Rintaro.

That was the prevailing theory, at least on record.

In response to those waiting for his words, Dragius folded his hands in front of his face and spoke mysteriously.

「Hinosmera, the Purgatory Mysterious being, was the central figure in the “Mt. Fuji Explosion Disaster” that occurred 10 years ago.」
