This Host Is Clearly Weak Yet Overly Confident

Under the bright moonlight, Yu Luo painstakingly made his way from the empty male teacher dormitory building to Walter's room. "There isn't even a hallway light. What does Theresa even think of male teachers?"

Complaining, Yu Luo fumbled in the dark to open the door. Just as Walter had said, the door wasn't locked from the inside, leaving it open for Yu Luo. He turned on the living room chandelier. The living room was empty. Walter's door was closed, and there wasn't a sound.

"Is he asleep?" Yu Luo muttered softly, also moving quietly to avoid waking Walter. After a quick wash, he put on the clothes Walter had prepared and returned to his own room.

"Old Wa is really a good guy. The clothes even fit perfectly." Yu Luo forcefully threw himself onto the soft, large bed and bounced a couple of times. Hugging the velvet comforter, his face was full of a happy smile. "Ah, I can finally get a good night's sleep!"

"Snap." Yu Luo casually turned off the bedside lamp, and the room plunged into darkness, leaving only the faint blue glow of Raikiri's blade.

"Hey, aren't you going to do any summons? Little Black's rate-up is ending soon!" Just as Yu Luo was groggily about to fall asleep, the system's slightly anxious voice cut through his drowsiness.

"Summon what!" Yu Luo impatiently waved his hand, as if shooing away a fly. "My years of being cursed in Africa have taught me that if you force yourself to chase after a banner that's already skewed, heh."

Yu Luo let out a light laugh, his tone full of wistfulness. "I'm the kind of man who pulled five copies of Little Mo from the Bride Nero banner three times and Okita Souji's banner twice. If it's over, it's over."

"Uh..." The system was momentarily speechless, unsure how to comfort Yu Luo. After a long pause, it finally managed to squeeze out a sentence: "It's okay, have you heard of Twelve Trials? Someone back then only got one copy of Old Sword on the Twelve Trials banner. You're still doing alright."

"I'm sleeping. Don't bother me." Yu Luo's sore spot had been touched, and he couldn't be bothered to deal with the system. He rolled over and continued his interrupted sleep.

"Don't, business has been too bad lately, no one's spending money. Help your little sister out!"

"Hey!" Yu Luo, completely unable to sleep due to the system's incessant calls, leaned back against the headboard in frustration, thinking to himself:

"Don't try to play the cute tea-selling girl with me! Just tell me what you want to trick me into!"

"When have I ever tricked you?!" The system cried out in injustice, pouting. "I not only worked hard to get you benefits, I even broke the system laws to help you level up. I can't go on like this!"

"So, what the heck is this so-called system law of yours!" Yu Luo stared at the ceiling with dead fish eyes, picking his nose, only missing a sword called Toyako in his hand.

"Um, the Chaldea Gate needs activation for its first clear. I think I might have told you about it, right?" the system asked uncertainly.

"That thing, didn't you say I had a few days to prepare?" Yu Luo retorted strangely, only to be met with the system's very guilty response:

"Uh... I seem to have gotten the time wrong..."

"Hmm?" Yu Luo suddenly had a very bad premonition, even forming a guess in his mind. "You don't mean to say that..."

"Uh... the time started counting from when you were unconscious..."

"So you started counting from when I woke up, realized something was wrong, and tonight at midnight is the final deadline, right?" Yu Luo finished the system's sentence expressionlessly, stating his guess.

"Teehee☆~"

"Stop trying to act cute like Sister Yoko with me! You scammer!" Yu Luo roared at the system in his mind, which was trying to get away with cuteness.

Yu Luo sat quietly for a moment, calming his anger. He calmly asked the system some important questions. "I'll ask, you answer. Cut the crap, understand?"

"First, if I go to another world through the Chaldea Gate, what will happen to my body in this world? Soul transfer or body transfer?"

"Don't worry about that, it's a complete body transfer!" The system tried its best to show off, answering Yu Luo's questions almost instantly to make up for its mistake.

"What about the time flow? Don't tell me I'll come back from clearing a dungeon and this world will be destroyed."

"Don't worry, we're a conscientious company. We use an eight-hour workday. No matter how long you stay over there, only eight hours will pass here."

"That's good then." Yu Luo breathed a sigh of relief. This way, he wouldn't have to worry about his disappearance causing panic, nor would he have to rack his brain to find an excuse to ask Theresa for leave.

"Do you have any information about the other world? So I can prepare a bit."

"I really don't." The system shook its head helplessly. "The world is in a quantum state. Only when you pass through the Chaldea Gate and the system observes your existence will the world be determined. You can think of it as the observer effect in quantum mechanics."

"Quantum mechanics again for everything..." Yu Luo stood up, took off his pajamas, and put on his own clothes, muttering. "You can create someone like you, so why do you always use quantum mechanics to explain things."

"Maybe it's easier for you to understand that way," the system offered its guess, only to be met with Yu Luo's merciless retort:

"No, my understanding is limited to the basic arithmetic of '1000 minus 7.' " Yu Luo looked at Raikiri, which was quietly placed on the table. After thinking for a moment, he sheathed it and tucked it into his waist. He then said to the system, "Alright, let's begin."

"Hmm?" Yu Luo's decisive action caught the system by surprise. "Aren't you going to prepare more?"

"What's there to prepare? There's no information. I'll just react as things happen. Why bother with all that fancy stuff? Just charge in."

"This host is clearly super weak yet excessively confident," the system muttered softly and activated the Chaldea Gate. A complex and dizzying magic circle suddenly lit up beneath Yu Luo's feet. Space rippled, and Yu Luo's figure gradually faded, eventually disappearing from the room. The magic circle also quietly vanished without a sound. The entire St. Freya Academy had no idea that someone had disappeared without a trace.

Yu Luo felt his eyes being enveloped by a soft white light, and his whole body felt weightless. There was no dizziness or disorientation from the spatial shift as described in legends. He simply felt like he was floating in space for a short while. As the sensation of his feet touching solid ground appeared, the white light before Yu Luo's eyes began to fade.

"Ding! [Demon Slayer: Kimetsu no Yaiba]: Demons are monsters that feed on human flesh and blood, possessing immortality. Their weaknesses are a fear of sunlight and wisteria flowers. Simultaneously, swordsmen dedicated to slaying demons have emerged among humans. In the dark corners of the world, the struggle between the two has lasted for centuries."

"Ding! Quest Issued: [Slay the Demon King]."

"[Slay the Demon King]: Slay the origin of demons, the Demon King Muzan Kibutsuji.

Reward: 20 Saint Quartz, Permanent activation of Chaldea Gate."

"Ding! Quest Issued: [Slay the Twelve Kizuki]."

"[Slay the Twelve Kizuki]: Slay one Upper Rank demon to receive 1 Summoning Ticket, slay one Lower Rank demon to receive 1 Saint Quartz."

"Ding! Quest Issued: [Comprehend Breathing Style]."

"[Comprehend Breathing Style]: Comprehend a Breathing Style unique to yourself.

Reward: 5 Saint Quartz."

Yu Luo's mind was bombarded by a string of system notifications. Before he could even observe his surroundings, his attention was captured by the system's quests.

"There are demons in this world?! Are they like Sadako or Kayako?!" Yu Luo asked the system with a slight hint of excitement.

"You're overthinking it. They're more like Ibuki Suika. Sadako and Kayako are called vengeful spirits," the system rolled its eyes. Yu Luo, however, was seen stroking his chin thoughtfully.

"Watermelon types are also great, pretty little ladies, and non-humans."

"Heh." The system let out a cold laugh. When it had just issued the quest, it had already gotten a general idea of what the demons in this world were like. As for Yu Luo's fantasies, the system mercilessly shattered them. "Little ladies and non-humans, definitely. As for whether they're pretty..."

"You'll get to see soon enough."

"Ah!!!!!" A piercing scream suddenly rang out, its extreme penetrative power reaching Yu Luo's ears, making his scalp tingle.

Can't find it by searching the book title, you can try searching the author, maybe they just changed the name!
