My daily life of exorcising demons and falling in love with a witch.

"Hmph, that scumbag brother definitely didn't say anything good about me!" Erina said with a look of disgust. "Is he always bragging about how he teases his silly little sister?!"

"Miss, aren't you just exposing yourself?" Yixing retorted. "Don't admit that you're not very bright."

"What do you mean by facts! Where am I not smart?"

The young lady looked like she really wanted to throw a dumpling at him.

Unfortunately, the sewer wasn't clean, and she was afraid of getting it dirty, so she couldn't take it out.

Otherwise, the durability of the plush dumpling would definitely decrease by one.

Shinshoujima Village watched their interaction with a smile and said something that made both of them a little embarrassed.

He said that Yoda Yusuke did mention that his sister was often silly and funny, but he didn't say anything bad about her otherwise.

Yusuke also spoke highly of Yoshiyuki, saying that his younger brother was a very good person with superb swordsmanship. He was also impeccable in taking care of the young lady.

Shinjojima Village also mentioned that Yusuke jokingly said that their relationship was really close, and if it weren't for their special status, he would have helped to bring them together long ago, and maybe they could have gotten married right after graduating from high school.

Both Yoshiyuki and Erina felt their faces burning and were too embarrassed to continue the conversation.

He wanted to let go of the young lady's hand, but just as his fingers began to loosen, Erina gripped it even tighter.

"Oh dear, Miss Yoda, why is your face so red?" Shinju Shimamura looked at them and said teasingly, "Even though it smells a bit bad, there's no need to hold your breath. Don't suffocate yourself."

"Who would suffocate themselves like that!"

Erina couldn't help but make this comment.

Wu Lili then spoke up, puzzled.

"I'm curious how Shuten-dōji usually gets back to the surface. Does he also go through the sewers? He must get covered in sewer odors, right? Does he go on dates with girls smelling like that?"

"As long as it doesn't get stained, the smell will dissipate after a while in a well-ventilated area," Yixing suggested after thinking for a moment. "You could also spray on some men's cologne. It'll add a touch of romance and make it easier to impress young girls."

"Wow, Maekawa-kun, you seem to have a lot of experience!" Wu Lili asked with great interest, "Do you often walk through the sewers?"

"How is that possible!"

"So, you often trick girls into going on dates?"

"Of course not!" Yixing immediately clarified, "Don't make me sound like a criminal!"

He has a clear conscience; he has never done anything like this before.

"That's right." Erina also agreed, "Hmph, I know best what my servant does every day! He never goes on dates with girls!"

"My master understands me the most." Yixing was deeply moved by her timely support.

However, the young lady's next words startled him.

"Yi-xing is busy figuring out how to look better in women's clothing every day, how could he have the mind to flirt with girls?"

"Seriously? This even involves cross-dressing?" Yoshiyuki blurted out, then noticed that Wu Lili and Investigator Shimamura were giving him strange looks. He quickly exclaimed, "Wait! She's wrong! I've never researched cross-dressing!"

"It's alright, Maekawa-kun." Wu Lili patted his shoulder earnestly, showing an expression of understanding and knowing: "Although everyone has things they are not comfortable admitting, cross-dressing is a perfectly normal hobby in my opinion."

"Don't talk like it's true I cross-dress!"

Yi Xing felt that this matter could not be discussed any further, otherwise, under the persecution of the young lady, the more he explained, the more confusing it would become.

Fortunately, the chatter ended there—Erina said that the place where Shuten-dōji's aura was coming from was very close, just down the steps ahead.

"But it's all empty over there, there's nothing there at all." Wu Lili asked curiously, "Are you sure this is the right place? Or somewhere deeper inside?"

"I'm absolutely certain, this is it!" Erina said confidently. "From this distance, I can already sense the energy of the barrier. Shuten-dōji doesn't live directly in the sewers, so the location I'm sensing right now isn't actually him, but rather the entrance to the barrier."

"I see. Your tracking technique is truly impressive." Shinju Shimamura clicked his tongue in amazement. "But doesn't this count as leaving Akihabara? The spell should have failed, right?"

"If the alternate dimension he enters is indeed another independent world, then the tracking spell will fail," Erina explained earnestly. "But this barrier is attached to the mortal world, that is, the human realm. So as long as he doesn't leave the barrier, the tracking spell will continue to reveal the location of the entrance."

Since everyone present was a spiritualist, her explanation was easily understood by all.

There are two types of alternate dimensions: those that exist independently, or those that exist in relation to something.

An independent alternate dimension will still exist even if all entrances are sealed, but it will be impossible to communicate with each other by ordinary means.

For example, the main passage to the Land of the Dead, the Gate of the Underworld, was sealed off by the Witch of the Underworld.

A secondary dimension that exists in association with something will also disappear once the carrier it is attached to is gone.

For example, if it was made using a magical artifact, then once the artifact is destroyed, the alternate dimension will also collapse.

There are many kinds of attachments, and Shuten-dōji simply chose the Eternal World.

Such attachments cannot be destroyed and have a high level of security, but it is also difficult to create a large and complex alternate dimension.

At this moment, Erina used her perception magic to analyze that the alternate dimension created by the target had not been enhanced by other means.

So, as long as he's killed, the barrier will disappear naturally. No additional action from the Fourth Special Investigation Division is needed.

Although the entrance to the barrier was hidden, Erina easily broke the spell and cast a spell to make the entrance appear on the wall.

It was a purple, vortex-shaped portal. Stepping through it would allow one to enter the world where the target was hiding.

Since the other party is most likely Shuten-dōji, Investigator Shimamura advised everyone to be prepared before going in.

Actually, saying this on its own is quite serious.

The problem is that Shinjojima Village made this statement while seriously lighting a cigarette.

"Everyone who needs to go to the toilet, hurry up! If a fight breaks out soon, you'll have to hold it in! Haha, although someone as strong as me can easily hold the gun in one hand and fire it in the other."

"Don't you only have one pistol?" Erina looked at the unusually conspicuous blue revolver at his waist, somewhat puzzled.

"The other one is an abstract gun," Shimamura replied, feigning seriousness. "You surely understand, Maekawa-kun, right?"

"Ugh, that's enough!" Yoshiyuki was almost bursting with embarrassment. "Officer Shimamura, can you please shut up?"
