An emergency announcement via the mysterious blackboard declared that a raid battle would be taking place.

"W-What's a raid battle?"

Subaru tilted his head in confusion.

"Oh, right, you don't really play social games, do you? In online games, 'raid' is what they call events where multiple players team up to fight a common enemy or clear a dungeon."

The one who answered was Serina.

Seemingly, Subaru wasn't the only one unfamiliar with the term; many of the other girls looked as though they were just now getting it.

Judging by the reactions, the only ones who knew what a raid was me, Chiyu, Serina, and Runa.

It wasn't limited to games; there are plenty of terms specific to a field that outsiders wouldn't understand.

It was no surprise that some people didn't know the word "raid."

[Raid Battle: Monsters]

Duration -- Until the end of the eleventh day, or until the target monster is defeated or all participants leave.

Content -- Aim to defeat the target monsters placed throughout the island.

Rewards -- Upon successful defection, "Return Right," "Ability Awakening," "Survival Bonus," and "Points" will be granted to participating members based on their contribution level.

"So there are rewards besides 'Return Rights'..."

Since bonuses like the bonus area had existed without prior notice, it wasn't out of the question that other types of rewards would appear in this format.

The issue is that as the variety of rewards increases, it seems the difficulty of clearing the events has risen accordingly.

By the way.

"Return Rights" are the rights to return to Japan.

Using these supposedly allows you to revert to the timeline immediately prior to your transfer.

The "Survival Bonus" is a reward obtainable on a daily basis; for each grant, your lifespan extends by one day.

Since the possibility of death by accident or suicide remains even after receiving this, it appears to be a mechanism solely for extending the biological survival limit of the body.

"Points" are a mysterious numerical value that appears to be granted based on monster culls or judgments made by the Mysterious Blackboard.

Upon returning, a settlement process is conducted, and if this balance is positive, further benefits can be obtained; however, since I am unable to provide the specific figures, there is little room for analysis.

"If 'Ability Awakening' occurs, does that mean existing abilities are strengthened?"

"Probably, that’s how it works. But what happens to those who don’t have any?"

As Chi-iku and Shi-ne spoke, text appeared on the Mysterious Blackboard.

"Regarding 'Ability Awakening':

For individuals with abilities: Acquired abilities will be strengthened. I cannot answer questions regarding the specific details of each strengthening.

For individuals without abilities: Acquisition of an ability is possible. However, you cannot acquire abilities identical to those possessed by existing Abilites, nor abilities that exhibit significant similarity to them."

Everyone was shocked by this.

According to the current explanation, all of us are classified as Ability users, but this desert island is also home to many Nulls.

"So if 'same is bad' means that copying because Sakusuke's ability is convenient, like 'I want one too,' that's off-limits, right?"

"As for whether anyone could handle it as deftly as Master, that's another story. But without this restriction, every Null would undoubtedly choose the [Craft] Ability, so from an Observer's standpoint, I think the judgment is understandable."

Lora, the maid, responded to Runa's inquiry.

Indeed, if the Blackboard wanted to increase the number of Ability users, it was probably for some reason like wanting more interesting events to unfold, meaning there was no point in having multiple people with similar abilities.

That said, depending on how strong the monsters are, I felt it would be difficult for Nulls to shine in this event.

There might still be a chance if their Ability-using teammates cooperated to let them take the glory.

"I'm interested in the rewards too, but what piques my curiosity is the monsters strong enough to warrant such rewards."

I nodded at Shinhou's words.

The text regarding the duration was also terrifying: "Until the target monster is defeated, or until all participants withdraw."

All participants withdrawing meant there was a possibility they would receive the death penalty and return to Earth.

"I see. If it's just monsters like those currently deployed, we can handle them even in large numbers..."

Since our party includes Yurina, who possesses the [Barrier] Ability, we could crush enemies from a safe zone.

• Target Monster — Regarding the Behemoth

A giant monster resembling an elephant.

Herbivore. It devours all vegetation on the island in approximately twenty-four hours.

Monsters deployed within the island revere the Behemoth as their king and obey its commands.

During this event, Behemoth will prioritize targeting those who possess the 'Right of Return.'

Notes

Vegetation lost to the Behemoth requires four times longer than usual to regenerate.

Devouring the flora of a vast island in a single day and reducing its regeneration speed by seventy-five percent.

Considering the goal of survival on this island, it is the worst possible opponent.

Furthermore, having Treants and Archvarks under its command makes things extremely troublesome.

But, this content is simply too...

"Ah... um... I apologize if this is a misunderstanding on my part, but... the Mystery Blackboard thing seems to have been planned in response to us having formed our class."

Professor Luminous said with anxiety.

She seemed to have come to the same conclusion as me.

「Maybe that’s it. For the Mystery Blackboard, having all of us form a cooperative relationship amounts to nothing but 'stagnation.' Maybe they triggered an 'Emergency Event' just to stimulate things and get the observation results they wanted.»
"What a cheap trick!"

I agreed with Shouko's blunt reaction.

But I also felt that since the Mystery Blackboard was capable of such a move, there wasn't much point complaining.

Pushing back wouldn't yield any concessions from someone like this.

We should focus on figuring out how to take down Behemoth.

Besides, if we managed it well, there could be benefits to gain.

"Hey, do you think my ability can prevent Behemoth from invading?"

"Behemoth's attacks and trampling are capable of breaking through the barrier deployed by Yurina in the dream realm."

Yurina made a bitter expression.

It was certainly painful to think that such an expensive barrier would be destroyed.

Especially since our party, which included holders of the 'Right to Return,' was already being targeted with priority.

"If it's between appetite and a holder of the 'Right to Return,' which one would take precedence?"

Utsune placed her hand on her chin, her face contorted in thought as she asked.

『If a bearer of the "Right of Return" is sighted, track that target until they are lost from view.』

"What happens if we run into the sea?"

Chiga asks.

I see. Combining this with the answer Shion received earlier, luring them toward the water might actually limit the damage to the vegetation.

『Under current conditions, participants cannot move far from within the island's boundaries. The operational range of the participants and the Behemoth perfectly overlap.』

So escaping into the shallows is pointless against a Behemoth, and we might not even be able to reach open water in the first place.

It looks like exploiting the Behemoth's programmed instincts to make things easier is out of the question.

"How do we defeat it? Does its health bar turn red when it gets close to dying?"

Junna asks.

Unlike a game, it’s definitely frustrating not knowing when the opponent will fall.

At least if I could see it visibly weakening, that would be one thing... but...

"Behemoth is a monster that can be slayed."

The reply was simple.

Since it’s not an impossible clear, it just comes down to what you guys can do now.

...Even so, we thought we had organized our party classes, and they still go ahead with hosting a event like this.

It seems the Mysterious Blackboard isn't looking forward to us bringing peace to this desert island.

Although it goes against my will, Behemoth must be defeated no matter what.

An emergency announcement by the mystery blackboard announced that a raid battle would be held. "W-What's a raid battle?" The maids tilted their heads.

"Oh, you don't play a lot of mobile games, do you? In online games, it's an event where multiple players fight a common enemy or clear a dungeon," replied Serina.

There seemed to be many girls who didn't know about it, as they were nodding in understanding.

From their reactions, it seemed only I, Chiyu, Serina, and Minato knew about it.

There are many terms in any field that are not understood by those who are not familiar with it, not just in games.

It's not surprising that there are people who don't know what a raid is.

『・"Raid Battle - Monster"

Period - Until the target monster is defeated or all participants leave after the eleventh day

Content - Aim to defeat the target monster placed on the island

Rewards - Award "Return Rights," "Ability Awakenings," "Survival Bonuses," and "Points" to participants who contributed to the defeat of the monster』

"There are rewards other than 'Return Rights,' huh..."

Since there were bonus areas and other perks without prior notice, it wasn't strange for other rewards to be given in this form.

The issue is that as the types of rewards have increased, the difficulty of clearing the event has also risen, hasn't it? By the way.

The 'Return Right' is the right to return to Japan.

It seems that using this allows one to return to the timeline just before the transfer.

The 'Survival Bonus' is usually given every day, and each time it's given, one's lifespan increases by a day.

Even with this, the possibility of accidental death or suicide remains, so it seems to merely extend the physical survival limit.

'Points' are apparently mysterious values given for defeating monsters or based on the judgment of the mystery blackboard.

At the time of return, a settlement is made, and if this is positive, one can receive additional benefits, but since no specific numerical values are given, there's little room for speculation.

"Does 'Ability Awakening' strengthen the ability if you already have it?"

"Probably. But what about those who don't have it?"

When Chiyo and Shion speak, words appear on the mystery blackboard. '• About "Ability Awakening".

For those with abilities, the acquired ability will be strengthened. However, the specifics of the strengthening cannot be disclosed.

For those without abilities, it is possible to acquire an ability. However, the same ability as existing ability users, as well as abilities with significant similarity, cannot be obtained.' Everyone is surprised by this.

According to the explanation we've been given, we're all classified as ability users, but this desert island has plenty of non-ability users too.

"So, when they say 'no duplicates,' they mean we can't just copy Kousuke's ability, right?"

"Even if you can't handle it as well as my master, if there were no such restrictions, all the non-ability users might end up choosing the 'Craft Ability,' so I can understand the Observer's judgment."

The maid Roa answers Rinme's question.

Indeed, if the mysterious blackboard wants to increase the number of ability users, it probably wants more interesting things to happen, and having similar ability holders wouldn't really achieve that.

Still, depending on the strength of the monsters, it seems difficult for non-ability users to shine in this event.

If the ability users could work together to help them achieve something, there might still be a chance.

"I'm also curious about the reward, but the fact that there's a monster worth such a reward is also intriguing." I nod at Shinbo's words.

The phrase "until the target monster is defeated or all participants leave" is terrifying.

It means there's a possibility that everyone will be forced to leave, which would mean a death penalty and a return to Earth.

"That's true. With the monsters currently placed, we could handle a lot of them, but..."

Our party has Seirine, who has the 'Barrier Ability,' so we could even crush the enemies from a safe zone.

『・Target Monster--About the "Behemoth" A monster resembling an elephant, and huge.

Herbivorous. It can devour all the plants on the island in about twenty-four hours.

The monsters placed on the island worship the Behemoth as king and follow its orders.

During this event, the Behemoth will prioritize those who possess "Return Rights." Note

Plants lost to the Behemoth will take four times as long to respawn.

It can devour all the plants on the vast island in a day and slow their regeneration to one-fourth their normal speed.

Considering survival on this island, it's the worst possible opponent.

And having Trent and Arvanc under its command is extremely troublesome.

But this is too much...

"Um, if this is a misunderstanding on your part, I apologize, but... the mystery blackboard, or rather, whoever it is, seems to have planned this in response to us uniting the class..."』

Luminas-sensei says anxiously.

She seems to have thought the same thing as me.

「Yeah, maybe. For the mystery blackboard, all of us working together is just 'stagnation.' Maybe it triggered an 'emergency event' to give us the desired observation results by providing a stimulus.」
「What, that's not evil!？」

I agreed with Shouko's honest reaction.

But, since the mystery blackboard can do that, there's nothing we can do about it.

We won't get any concessions even if we argue.

We should focus on how to defeat Behemoth.

Besides, if we do it well, there are benefits.

「Hey, can my ability stop Behemoth's invasion?」

『Behemoth's attacks or trampling can destroy the barrier that Sei Rina is spreading.』 Sei Rina made a bitter face.

It's indeed painful to have the barrier destroyed.

Especially since our party, which includes someone with 'return rights,' is targeted first.

「If you have an appetite and 'return rights,' which would you prioritize?」

Shion put her hand under her chin and asked with a thoughtful look.

『If a "Return Right" holder is detected, I will continue to pursue the target until I lose sight of it』

"What if we escape to the sea?" Chiyu asks.

Indeed, if I combine it with the answer I got from Shion's question, it seems that by leading them to the sea, the damage to the plants can be minimized.

『Currently, the participants cannot leave the island significantly. The range of participants' activities and the Behemoth's range of activities completely overlap』

It makes sense that fleeing to shallow waters would be pointless for the Behemoth, and they might not even be able to go out to sea.

It seems that taking advantage of the Behemoth's habits to make things easier is not possible.

"How do we even defeat it? Does the health bar turn red when it's about to be defeated?" Juumu asks.

Indeed, unlike in a game, not knowing when the opponent will be defeated is tough.

At least it would be better if it was obvious that it was weakening...

『The Behemoth is a monster that can be defeated』 The answer is simple.

Since it's not impossible to clear, it's up to you guys now.

...Still, considering that we've managed to gather the classes, it's surprising that they would hold such an event.

It seems the mysterious blackboard doesn't want us to bring peace to the desert island.

Annoying as it is to follow its objective, we have to defeat the Behemoth. Book edition on sale! Added to the bonus information activity report,
