Crossover Anime: The Heroine's Savior in the Other World

"If you're a thief for a thousand days, how can you guard against thieves for a thousand days?"

Kitahara Sousuke sprayed the spray in his hand into the air twice, then waited anxiously for the drug to take effect. After all, it wasn't inhaled directly; the effect of a drug diluted in the air before entering the body shouldn't be too overpowering.

Even if something unexpected happens, I still have my right hand, right? There's nothing that can't be solved with some glue.

However, after waiting for quite a while, I didn't experience any symptoms like fever or shortness of breath. I tried taking a few deep breaths, but it still didn't have much effect.

Is it specifically targeted at women? Or is it ineffective unless inhaled directly?

Kitahara Sosuke remembered that in the story, Akizuki Kozo always sprayed the product directly onto the victim's face. He unscrewed the nozzle cap, tried to put a little on his finger, and carefully applied it to the area around his philtrum.

"This amount should be..."

"You idiot, Sosuke, you..."

With a loud bang, the door made intimate contact with the delicate, white feet encased in over-the-knee socks once more, emitting a painful groan. Startled, Kitahara Sousuke's hand trembled, and half a bottle of liquid spilled directly onto his clothes.

"You, you...you have no shame!"

Ellie pointed a trembling finger at the computer screen in the room, which was paused on an indescribable image.

"No, please listen to my explanation."

Kitahara Sosuke quickly tightened the cap on the bottle and stuffed it under his pillow. Then he jumped up, grabbed Airi's hand, dragged her into the room, and slammed the door shut with a bang.

"What are you doing? Keep your voice down. Don't you know how to knock before entering a house? Marina and Mom are downstairs watching TV. Do you want to bring them all up?"

Kitahara Sosuke lowered his voice and, before he could even feel bad about wasting most of the medicine, quickly reached out and covered Airi's mouth, which was agape in an "O" shape.

What can I do? Guess who I'm doing this for? It's because I'm afraid of causing trouble for you all. How can you apply glue without side dishes?

"You actually secretly watched this kind of thing!"

Airi reached out and slapped the other person's arm away, her face flushed as she glared fiercely at Kitahara Sosuke.

"Your hands are so dirty, don't touch me with them!"

"Would you believe me if I said it was for love and peace?"

"My brother, who secretly hides under the covers alone... he should just die!"

Ellie felt a little excited, not sure if it was because she had stumbled upon her brother's secret, or because the two of them were so close that they could clearly feel each other's breath.

She wiped her lips with the back of her hand. "Why are Sosuke's hands so sweaty?" Airi thought to herself, her tongue unconsciously tracing the spot where Kitahara Sosuke had just touched.

"Sweet..."

At only 158cm tall, Airi was squeezed against the door by Kitahara Sosuke, who was over 180cm tall. Due to the huge height difference, Airi could only look up at Kitahara Sosuke's chin.

The air around her seemed to be filled with Kitahara Sosuke's scent. Surrounded by her brother's aroma, Airi felt dizzy. She placed her hand against his chest, but couldn't get any strength in.

"The lowly Sousuke is actually... kind of handsome?"

Ellie stared at him with her big, watery eyes, her mouth slightly open, her not-so-high breasts heaving rapidly, and her two smooth, soft thighs pressed together under the hem of her white nightgown, rubbing against each other involuntarily.

"Ellie, why is your face so red?"

Kitahara Sosuke reached out and touched the other person's flushed little face with the back of his hand; it was frighteningly hot.

"Woo..."

A suppressed moan escaped her lips. When Kitahara Sousuke touched her, Airi trembled and her legs went weak.

"Nice, the effect is great... what a load of rubbish!"

Kitahara Sosuke stared at the words "In Heat" in the special status indicator with mixed feelings. "Very good, the test results are clear: it's effective on women, but ineffective on men. The onset speed seems to be even faster than predicted. Perhaps Airi is just more sensitive?"

But a new problem has arisen: my sister, who is alone with me in a room, has taken drugs. What should I do? I need help urgently.

"Onii-chan..."

The soft, sweet voice quickly pulled him back to reality. The girl, sitting on the floor in a duck-like position, clutched the hem of the person in front of her tightly, resting her head near his lower abdomen. Her pearly teeth parted slightly, and she took a button from Kitahara Sosuke's clothes into her mouth, as if she had found a fun toy.

"We're in big trouble."

Kitahara Sousuke silently apologized, bent down, put one arm around the girl's slender, boneless waist, and slipped the other arm under her fair, plump thighs. With a slight effort, he lifted her up in a princess carry.

Ellie cooperated by wrapping her arms around the other person's neck and affectionately nuzzling her face against the other person's chest.

"Don't rub it, don't rub it, it's over... my heart eyes are about to pop out."

Kitahara Sousuke hadn't forgotten that most of the medicine had been spilled on his clothes.

When was the last time the two of them were this close? I've forgotten. It seems like ever since middle school, Ellie has rarely been this clingy… Oh dear, is this the time to be thinking about this?

Afterwards, I wiped her with a damp towel and tried all the massage techniques I found online. Apart from making Ellie a little more obedient, her body temperature and flushed face did not improve at all.

"..."

Kitahara Sosuke lifted Airi off the bed and placed her comfortably on his lap.

Ellie was still fidgeting restlessly.

"hiss--"

"I'm sorry, little bunny, we don't have any carrots. Have something else to satisfy your craving for now..."

Chapter Eight: What to do if you lose the right to be a human being

With a violent tremor, Ellie's body tensed like a bowstring, then slowly relaxed. Her lifeless eyes stared blankly at the ceiling, a few strands of hair damp with sweat clung to her delicate face, and she murmured:

"Onii-chan... Suki..."

About half a minute later, the unfocused pupils gradually regained their focus, transforming from initial confusion to shock, and then mixed with a touch of shame and indignation.

"you you……"

Airi yanked the blanket off, hiding her body except for her head, her watery eyes fixed on Kitahara Sosuke.

"Idiot, pervert, scum! What did you just do?!"

"Let me make this clear first, you were the one who started by rubbing against me like a lovesick woman."

Kitahara Sousuke skillfully shifted the blame to someone else first.

"That can't be... We're siblings!"

Ellie recalled what had happened half an hour ago, and a blush began to spread from the base of her ears. She didn't know why, but her silly older brother had just gotten a little closer, and her heart was beating so fast.

Then, during just normal daily contact, I almost missed it. After that, I was hugged by my idiot older brother, and so on... I remember everything, but my brain seems to be overloaded and I can't think at all.

I just felt that Sosuke smelled particularly good today, with lavender-scented laundry detergent, lemon-scented shower gel, and some other unidentifiable scent mixed in.

"Woo——"

Ellie wrapped herself up like a caterpillar and rolled around on Kitahara Sosuke's bed, whimpering like a wounded little animal.

Kitahara Sosuke stood awkwardly by the bed. Who knew this girl had developed the habit of barging in without knocking? She just happened to stumble upon him while he was researching Akizuki Kozo's medicine.

However, no matter how you look at it, I still got the better deal. Girls are easily embarrassed, so I had to coax her. So I bent down and gently patted the top of her head.

"Ellie..."

"Don't say it!"

Ellie rolled over, her little face showing a look that said, "If you say one more word, I'll bite you to death."

"Forehead……"

"It's just a normal physiological reaction for teenage girls..."

No, that's right, I just requisitioned some lowly Sousuke... that's all. I didn't expect it to be just so-so.

Ellie forced a nonchalant air and said a few words like "so-so," but then the memory of what had just happened flashed through her mind.

"Well, anyway... consider that a reward for Sousuke's good performance today."

Ellie became more and more confident as she spoke, as if the girl who had been clinging to someone like a giant cat just moments before wasn't her at all.

"Okay, you can go now. I want to sleep for a while."

"But this is my bed..."

"go out!"

"..."

Once Kitahara Sosuke gently closed the door, Airi's tense nerves finally relaxed. She buried her pink face in the pillow, her little feet patting the soft bed alternately.

"I'm going to die, I'm going to die..."

"Onii-chan..."

……

"Nissan, are you going out?"

"Yeah, school starts tomorrow, so I'm going to get a haircut."

Tomorrow is the end of the summer break at Toyonosaki Private School. Students who are moving up from the first year of high school to the second year will be reassigned to new classes and will meet new classmates and teachers.

This saved Kitahara Sousuke the trouble of constantly accessing the vast amount of memory details in his mind to maintain the original complex interpersonal relationships at school, since after the class reassignment, there weren't many people who could be in the same class for two consecutive years.
