March 7th: "A planet, isn't that just the ground ordinary people live on? Exusiai, you don't even know that?"

Exusiai: "Oh dear, I really don't know. I only know that the land under my feet is called the Terra Continent."

Ren: "Exusiai's world is a bit special."

March 7th: "Oh, I see."

Momonga: "Simply put, it can destroy the world!"

Exusiai: "!!!! Is it that powerful?!"

Ren: "It's not that exaggerated. It's only theoretically speaking."

Momonga: "I don't care! Boss, take care of me!"

Ren: "Heh heh, you probably don't need my care. Perhaps it won't be long before you become very strong."

Momonga: "Huh?"

March 7th: "It's here! Ren's important hint!"

Momonga: "What do you mean?"

Unfortunately, Ren didn't answer. He had already slipped away because Eriri had arrived.

"Ren, I'm here!" Eriri opened the door.

"Hmm???" Looking at Yukino and Yui Yuigahama, she froze. Two beautiful girls. One of them was even the school's unreachable beauty, Yukino Yukinoshita! Did I come to the wrong place? Seeing Ren... I didn't come to the wrong place?!

"You're here." Ren opened his eyes, a smile in them.

"Huh? Didn't you ask me to come? I didn't come voluntarily." Her tsundere attitude surfaced again.

After Eriri entered, she sat on the chair next to Ren. She occasionally glanced at Yukino and Yui Yuigahama.

"Let me introduce everyone, this is Sawamura Eriri. She's a new member of our club, though only in name."

"Yukino Yukinoshita." Yukino introduced herself concisely as always.

"I'm Yui Yuigahama, Yahallo!" Yui Yuigahama was still full of energy.

"Ya... Yahallo..." Eriri's mouth twitched, and she replied with a dry laugh.

"Didn't you say there was another club member? Is she not here?" She looked left and right but only saw Yukino and Yui Yuigahama.

Ren helplessly introduced Kato Megumi, who was sitting on his right. "This is Kato Megumi, she's the other club member."

"Hello." Kato Megumi replied calmly.

"When?!" Before Eriri could speak, Yui Yuigahama exclaimed.

"..." Eriri was indeed startled. But why didn't the other person in the club know either? In fact, Yukino only just discovered Kato Megumi now. She always made people unconsciously overlook her.

"This is Kato Megumi's special ability, a special presence that makes others think she's not there." Ren spoke proudly, as if introducing his treasure.

"It's just that my presence is faint." Megumi's voice always lacked emotion.

'It's like a superpower,' Eriri complained in her mind. But upon closer inspection, Kato Megumi also seemed to be a beautiful girl! Ren was the only boy in the club! The rest were all beautiful girls. This was very wrong! It seemed she would also have to come to the club from now on. It would take up some time from the art club. But it wasn't a big problem. She drew doujinshi at home every day when it came to art.

With Eriri's addition, the Supernatural Research Club became an official club. However, after this day, a strange thing happened.

Eriri took three days off. Ren called to ask, and she said she was sick. She still wasn't better after three days?

Today, Ren bought some Solace and decided to go to her house to check on her.

"This is..." As soon as he arrived outside Eriri's house, Ren sensed something abnormal. In his eyes, he saw the entire house entangled with a strange black aura. Frowning, he walked forward and rang the doorbell.

"Ding-dong!"

He waited for a while. No one responded. Something had happened. With a flick of his finger, the door was forced open by a huge power. Inside the room, black mist was drifting everywhere.

"Hmm?" This aura... is it a demon? The black aura not only contained the aura of evil spirits but also demons! In reality, Ren had encountered very few demons. This was because the supernatural phenomenon had not yet exploded in growth.

Demons are different from evil spirits. Evil spirits are formed from the obsessions and souls of the deceased. Demons are monsters from the other shore, generated from human negative emotions. They reside in deeper blind spots and cannot be directly seen or touched by humans. Demons can intensify human negative emotions, and in severe cases, they can even lead to death. Both are beings that ordinary people cannot touch or perceive. But what happens when the two merge?

In Ren's eyes, the evil spirit aura was merging with the demon aura. The black mist inside these houses was not invisible. It was visible even without spiritual sight!

"Father!" Eriri's cry of alarm came from a room. Ren instantly teleported over, and the door shattered upon impact!

What met his eyes was a crazed man, wielding a knife and slashing. His targets were a terrified Eriri, and another woman with a different hair color but a face extremely similar to Eriri's—Sawamura Sayuri, Eriri's mother.
