This Host Was Obviously Weak but Overconfident

By the bright moonlight, Yu Luo painstakingly felt his way through the empty male teachers' dormitory building to Walter's door. "There aren't even any hallway lights. What exactly does Theresa think of male teachers?"

Grumbling, Yu Luo opened the door in the dark. Just as Walter had said, it had not been locked from the inside and had been left for him. After turning on the chandelier in the living room, Yu Luo found the place completely empty. Walter's bedroom door was shut, and there was not a sound.

"Already asleep?" Yu Luo muttered quietly. He also deliberately softened his movements so he would not wake Walter. After washing up a little, he put on the clothes Walter had prepared and returned to his room.

"Old Walter really is a good guy. Even the clothes fit perfectly." Yu Luo threw himself hard onto the soft bed, bounced twice with all his strength, then hugged the velvet quilt with a blissful smile. "Ah, I can finally get a good night's sleep!"

Snap. Yu Luo casually switched off the bedside lamp, plunging the room into darkness. Only Raikiri's blade still emitted a faint, ghostly blue glow.

"Hey, are you really not going to roll? Little Black's rate-up is about to end!" Just as Yu Luo was drifting off, the system's slightly anxious voice reached him and chased away his drowsiness.

"Roll what?" Yu Luo waved a hand impatiently as though swatting flies. "My years in gacha hell have taught me that if a banner has already betrayed you, forcing yourself to keep chasing it... heh."

Yu Luo chuckled, his tone full of melancholy. "I'm the man who got a max-NP Little Mo from three Bride Nero banners and two Okita Souji banners. If it ends, it ends."

"Uh..." The system was briefly speechless, unsure how to comfort Yu Luo. After a long while, it finally squeezed out, "It's fine. Have you heard of Twelve Trials? Someone once spent twelve packs to get just one Old Sword. You've got it pretty good."

"I'm sleeping. Stop bothering me." Having had his painful memories brought up, Yu Luo could not be bothered with the system at all. He turned over and continued his unfinished sleep.

"Don't! My recent performance has been terrible. Nobody's paying to win. Help a girl out!"

"Hey!" The system's relentless calls completely chased away Yu Luo's sleepiness. He helplessly leaned against the headboard and complained inwardly:

"Quit pretending to be some tea-selling girl! Just tell me what you're planning to scam me with!"

"When have I ever scammed you?!" The system cried out in grievance. "I worked so hard to get you benefits, and I even broke system law to power-level you. I can't live like this anymore!"

"So what the hell is this so-called system law?" Yu Luo stared at the ceiling with dead-fish eyes, picking his nose. The only thing missing was a sword called Toyako in his hand.

"Well, there was an activation requirement for clearing Chaldea Gate for the first time. I should have probably maybe told you about it, right?" the system asked uncertainly.

"Didn't you say I had a few days to prepare for that?" Yu Luo asked strangely, only to receive the system's extremely guilty reply:

"Well... I think I got the timing wrong..."

"Hm?" Yu Luo suddenly had an extremely bad feeling. He even formed a guess. "You don't mean..."

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

"So you counted from when I woke up, realized something was wrong, and found out that midnight tonight is the final deadline, right?" Yu Luo expressionlessly picked up where the system left off and stated his guess.

"Teehee☆~"

"Quit acting cute like Sister Yoko to get away with this! You scammer!" Yu Luo roared at the system in his mind as it tried to muddle through with cuteness.

Yu Luo sat quietly for a while, calming his anger before coolly asking the system several important questions. "I ask, you answer. Cut the crap, understand?"

"First, when I go to another world through Chaldea Gate, what happens to my body in this world? Is it soul transmigration or physical transmigration?"

"Don't worry, it's definitely physical transmigration!" The system did its best to make up for its mistake, answering almost instantly whenever Yu Luo asked a question.

"What about the flow of time? Don't tell me that when I clear the dungeon and come back, this world will have already been destroyed by Honkai."

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

"That'll do." Yu Luo breathed a sigh of relief. That way, he would not need to worry about his disappearance causing a panic, nor would he have to rack his brains for an excuse to ask Theresa for leave.

"Do you have any information about the other world? So I can make some preparations."

"Not really." The system helplessly shook its head. "The world is in a quantum state. Only after you pass through Chaldea Gate, allowing the system to observe your existence, will the world become fixed. Just think of it as the observer effect in quantum mechanics."

"Quantum mechanics again whenever there's no answer..." Yu Luo stood up, took off his pajamas, and changed into his own clothes as he complained, "You can create something like yourself, yet you still use quantum mechanics to explain everything."

"Maybe because it's easier for you people to understand," the system offered its guess, only to receive Yu Luo's merciless mockery:

"No, my understanding is limited to addition, subtraction, multiplication, and division by thousands. Like 1000 minus 7." Yu Luo looked at Raikiri resting quietly on the table. After some thought, he sheathed it and hung it at his waist. "All right, let's begin."

"Hm?" Yu Luo's swift decisiveness caught the system off guard. "You're not going to prepare some more?"

"What's there to prepare? We have no information, so we'll deal with whatever comes. Why bother with all that flashy nonsense? Just charge in and get it over with."

"This host was obviously weak but overconfident," the system muttered softly as it activated Chaldea Gate. A dizzyingly complex magic circle suddenly lit up beneath Yu Luo's feet. Ripples spread through space, and Yu Luo's figure gradually faded before finally vanishing from the room. The magic circle quietly disappeared as well without making a sound. No one in St. Freya Academy knew that someone had vanished without a trace.

Yu Luo felt his eyes enveloped by gentle white light, and his whole body seemed weightless. There was none of the legendary dizziness caused by crossing space and time. It merely felt as though he had floated in space for a short while. Only when his feet touched solid ground did the white light before his eyes begin to fade.

One system message after another bombarded Yu Luo's mind. Before he even had time to observe his surroundings, the system missions had already seized his attention.

"This world has ghosts?! The kind like Sadako or the kind like Kayako?!" Yu Luo asked the system with a hint of excitement.

"You're overthinking it. The kind like Ibuki Suika. Sadako and Kayako are vengeful spirits." The system rolled its eyes, only to see Yu Luo stroking his chin thoughtfully.

"The Suika kind? That's not bad either. Pretty girls, and non-human ones at that."

"Heh." The system sneered. When it issued the missions earlier, it had already gained a rough understanding of what the demons in this world were like. It mercilessly shattered Yu Luo's fantasy. "They're definitely girls and non-human. As for whether they're pretty..."

"You'll find out soon enough."

"Ahhhhhh!!!!!" A shrill scream suddenly rang out, piercing straight into Yu Luo's ears and making his scalp tingle.
