A Scientific Urban Detective.

Chapter 921 Taking a Bath
Shirai Kuroko used "spatial teleportation" to return to the neighborhood where the "Seventh School District Student Dormitory" was located. After carefully scouting the area, she cautiously moved towards the dormitory building.

After confirming that she was not seen and having avoided nearby surveillance cameras, Shirai Kuroko finally reached a suitable distance and then activated "spatial teleportation" to move directly to her dormitory room.

Having "spatial movement" is convenient; you don't even need to climb through a window to enter the house, making less noise and almost impossible to detect.

The only thing to be careful about is that you might suddenly appear, which could be startling...

"Big sister, what are you doing?" Shirai Kuroko asked instinctively, searching for a familiar figure, but after actually seeing it, she couldn't help but ask.

On the way back, Shirai Kuroko was feeling a little uneasy and embarrassed, unsure of how to face Misaka Mikoto—after all, her feelings for the nameless senior had been exposed, and her relationship with her older sister had suddenly changed from roommates and friends to "love rivals"!
It is anticipated that dealing with this awkward situation will be a significant challenge for the two of them in the near future.

At least, because of the long-term concealment, Shirai Kuroko did feel some guilt towards her older sister.

However, when Shirai Kuroko saw the scene before her, she almost forgot her original complex emotions for a moment...

The first thing Shirai Kuroko saw upon returning to her dorm room was that her older sister, Misaka Mikoto, was wrapped in a bath towel, her hair still wet and dripping, looking as if she had just come out of the bath.

However, for some reason, this older sister was holding a comb in one hand and an unplugged hair dryer in the other, looking furtive, and squatting next to the dormitory's main entrance in a tactical assault-like posture.

"Big sister?" Shirai Kuroko was completely baffled by what she was seeing and could only ask, "What are you doing?"

Noticing that Shirai Kuroko had returned, Misaka Mikoto's eyes lit up, then she quickly put a finger to her lips: "Shh!"

"Keep quiet," Misaka Mikoto silently lip-read.

Then she tiptoed to Shirai Kuroko's side, a drop of water dripping from her hair leaving a clear mark on the floor.

"Onee-sama..." Shirai Kuroko whispered a reminder, "Your hair, the water..."

"I know, I did it on purpose." Misaka Mikoto threw what she was holding onto the bed, then grabbed Shirai Kuroko's shoulder. "There's no time to explain. The bathtub is already filled with water. Just bear with it for a bit and get in!"

As she spoke, Misaka Mikoto actually took action and helped Shirai Kuroko take off her clothes.

Because of the vigorous movements, he didn't even care that the towel on his body had fallen off.

"Huh? Why is this?" Shirai Kuroko was increasingly confused, but she didn't stop her older sister's actions. Instead, she opened her arms to cooperate with her. "Is this my punishment?"

"What punishment... I'll explain later. Okay, forget about the underwear, hurry up and go inside!" After taking off her outer clothes, Misaka Mikoto ultimately didn't touch Shirai Kuroko's underwear, and urged her to hurry to the bathroom, "The teacher is guarding outside!"

"Huh? Dormitory supervisor?" Shirai Kuroko instantly understood the situation.

Without saying anything more, he activated "spatial teleportation" and threw himself into the bathtub.

Almost simultaneously, there was a knock on the dormitory door.

Misaka Mikoto wrapped herself in a bath towel again, then grabbed a hairdryer and comb, pretending to style her hair.

Two seconds later, the door was opened directly—besides the two people who lived there, only the dormitory supervisor had the key to open the door.

Although it wasn't plugged in, Misaka Mikoto used her superpowers to power the hairdryer in her hand, making it whirring loudly.

"Sorry, teacher, I didn't hear the knocking..." Misaka Mikoto forced a smile. This was also the reason why Misaka Mikoto and Shirai Kuroko were so nervous and wary, because the dormitory supervisor had the power to open the door and conduct surprise inspections at any time, and if she was determined to inspect, it would be difficult to hide it.

"Misaka-san, why does it take you longer to take care of your short hair than the students with long hair?" the dormitory supervisor asked. "I remember you were blow-drying your hair an hour ago, right?"

“This…” Misaka Mikoto quickly said, “Because my hair got wet again… Yes, I accidentally got it wet when I woke up Shirai-san, so I washed it again…”

“Shirai-kun…” The dormitory supervisor turned to look in the direction of the bathroom.

Unlike the previous two room checks, this time the bathroom door was not locked, and it was even ajar, allowing a view inside.

Noticing the gaze from outside the bathroom door, Shirai Kuroko quickly submerged herself in the water, leaving only her head above water: "Good evening, teacher!"

The dormitory supervisor stared at her for a while before letting out a soft sigh: "Come out early, soaking in the bath for too long isn't good for your health."

"I...I understand!" Shirai Kuroko and Misaka Mikoto outside nodded together.

The dormitory supervisor turned and left the dormitory. Before closing the door, she casually asked, "Misaka, Shirai, you two aren't going out again, are you?"

"No..." Misaka Mikoto blurted out, then quickly corrected herself, "No, we didn't go out at all!"

Shirai Kuroko, soaking in the water, couldn't help but facepalm.

The dormitory supervisor didn't expose her, but simply said, "I'm talking about what happened this afternoon. You only asked for half a day off, but you didn't come back to school for class this afternoon."

"This..." Misaka Mikoto was speechless. So much had happened today, and the impact was so strong that she had forgotten about classes.

"Remember to go to the academic affairs office tomorrow to explain the situation," the dormitory supervisor said. "But don't worry, the head teacher knows about your situation and won't blame you too much. Just remember to ask for leave in time next time."

“Yes…yes!” Misaka Mikoto nodded repeatedly.

After thinking for a moment, the dormitory supervisor added, "You are still girls and students, so you should know when to stop doing adventurous things."

With a click, the door closed.

Misaka Mikoto seemed to have lost all her strength all at once, and sat down on the bed.

"We were actually exposed just now, weren't we?" Misaka Mikoto finally spoke after a while.

“Of course, it’s obvious at a glance,” Shirai Kuroko said. “It’s obvious that the dormitory supervisor just hasn’t called it out on yet.”

Recalling the scene of their conversation, Shirai Kuroko couldn't help but exclaim, "I never imagined that the teacher could have such a gentle side."

“Gentle? No…” Misaka Mikoto shook her head repeatedly, “If you hadn’t come back in time, you probably wouldn’t have been so ‘gentle’!”

The dignified Level 5 student, Tokiwadai Middle School's "Strongest Electric Shock Princess," looked visibly shaken: "The teacher's persistent room checks really scared me! That's why I had to resort to this tactic, saying you fell asleep in the bath because you were too tired..."
