In a crossover anime, the only way to become stronger is by marrying a wife.

There was a third person in the living room at this time, namely Goto Ichiri.

She watched silently as Tsukikawa Shu flirted with her friend, and once she was sure there was nothing for her to do, she got up and prepared to slip away.

Let's run away now while no one notices us! Otherwise, we'll be dragged into the battle later.

However, just as Goto Ichiri stood up and hadn't even fully turned around, her hand was grabbed.

"Where are you going?" Tsukikawa Shu asked.

“Ah… I guess there’s nothing more for me to do here, right?” Goto Ichiri said.

"How could there not be one?"

Goto Ichiri looked at Tsukikawa Shuu, and the other girl in his arms whose clothes were half-exposed.

"I'd better not get involved," Goto Ichiri said.

"Do you think that's possible?" Tsukikawa Shu tilted her head.

"..."

Goto Ichiri fell silent.

It seems... there's probably no way to avoid it after all.

……

……

Meanwhile, on the other side, Yukinoshita Haruno had just woken up and immediately headed towards Tsukikawa Shuu as soon as she opened her eyes.

"Where are you going?" Yukino Yukinoshita, who was sitting in the living room, asked, seeing her older sister's excited expression.

"I have some good news to share with you lately," Yukinoshita Haruno said with a smile.

"What good could possibly come from my sister's affairs?" Yukino Yukinoshita didn't take it seriously and didn't believe Yukino Haruno's words at all.

"Heh heh, don't be too surprised then," Yukinoshita Haruno chuckled.

Yukino Yukinoshita ignored her older sister.

Yukinoshita Haruno excitedly drove straight to Tsukikawa Shuu's house.

Standing in front of the door, she dialed Tsukikawa Shu's number.

“Hello, are you home?” she asked.

After a moment, the call was answered.

"Yes, it's here. Just push the door open and come in; it's not locked."

"Okay. I'm coming in now."

Yukinoshita Haruno pushed open the door.

Then, we arrived at the living room.

"Um……"

Yukino Yukinoshita looked at the scene that was still not over and silently turned her head away.

After a while, when there was no more movement inside, she returned with a look of shame on her face.

"You let me in just to see this?" she said angrily.

"Didn't you come to me on your own initiative?" Tsukikawa Shuu retorted.

"..."

That seems to be true.

Under the snow, Yang was at a loss.

"You bastard, doing that kind of thing in a tomb, aren't you afraid of getting retribution?" Yukino Yukinoshita said angrily, hands on her hips.

"What's wrong with that?" Tsukikawa Shu asked in surprise.

"The tomb's owner is gone, so what's there to worry about?"

"Hmm...that seems to make sense!"

Yukinoshita thought for a moment and nodded.

"Don't talk about this."

Tsukikawa Shu then walked over to Yukinoshita Haruno.

He wasn't even dressed.

"What do you want to do?" Yukinoshita asked.

"Since we're already here, why don't we come together?" Tsukikawa Shu asked.

"..."

Yukinoshita looked at Tsukikawa Shuu.

……

Listening to the noise around them, which included Yukino Yukino's powerless resistance and panicked voice, Ichi Nijika and Goto Ichiri simply put on their clothes silently.

"Then we'll be going now."

Holding Goto Ichiri's hand, they walked to the door, and Iji Chi Nijika turned around and waved to the inside.

The two people inside were busy with their business and did not respond.

"Let's go."

Ichi Niji shrugged, too lazy to pay attention to the two of them, and pulled Goto Ichiri aside.

"Oh."

Goto Ichiri followed her out of the house.

Before leaving, Goto Ichiri locked the door for Tsukikawa Shuu and even tested it to make sure it was completely locked before leaving with peace of mind.

……

……

Although she returned to her original world, it was still a very tiring day for Tsukikawa Shuu.

In the evening, he had just finished showering and was drying his hair with a towel, washing away the fatigue of the day.

Just then, Tsukikawa Shuu suddenly looked up and discovered that the system in the other world had sent a brand new notification.

[Given that some players in the Otherworld have surpassed the system's predicted strength, the subsequent conditions are being unlocked ahead of schedule.]

The currently running event is: Calamity.

[Current Disaster: Green Tide]

[Green Forest Frenzy: When the next Otherworld opens, a large number of plant-type monsters will appear, and the weather will become damp and gloomy. At that time, the attack power and movement speed of all plant-type monsters will increase by 100%]

[Duration of the disaster: Seven days]

If the calamity cannot be completely eradicated, it will sweep across all inhabited areas of the world within seven days.

[How to eliminate the disaster: Eliminate all monsters in the disaster, or directly eliminate the disaster boss.]

"They've come up with a new trick again."

Tsukikawa Shuu looked at the information about the disaster.

However, after reviewing the information, Tsukikawa Shu frowned.

The rewards are naturally very generous and substantial. If you can defeat this calamity boss, Tsukikawa Shuu will receive three legendary weapon chests and a large amount of refined ore.

This time, the boss of the calamity is level 80!

This is entirely aimed at pushing myself to my current limit.

I'm only around level 60 right now, and even with legendary weapons and legendary skill bonuses, challenging level 80 monsters is still quite difficult.

Open the forum, and you'll find a chorus of lamentations.

"These high-level monsters are going to kill us!"

"Level 80! Who can handle level 80 monsters these days?!"

"Should we all unite and fight together?"

"That's hilarious! Level 80 monsters are like a dimensional displacement attack against us; no matter how many people there are, it's useless!"

……

Tsukikawa Shuu has closed the forum.

Now we've reached another critical juncture.

"We still have to keep getting stronger."

Subsequently, Tsukikawa Shuu joined her own LINE harem group.

The people above are also discussing this.

"A level 80 Calamity boss, are we confident we can defeat it now?" Yukinoshita asked.
