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

Kitahara Sousuke offered a humble explanation, but feeling it wasn't very convincing, he simply acquiesced.

"Anyway, pinky swear with me..."

"Hook."

Marina stretched out her fair little hand, and Kitahara Sosuke could only nod and extend his right hand to hook the girl's finger with his little finger.

"Okay, Nii-san, you can go now, I'm going to sleep."

Marina felt much more at ease after receiving Kitahara Sousuke's promise, but she still felt a little embarrassed when she thought about the embarrassing scene in the bathroom earlier.

She had been nestled in his arms, not noticing at first, but then she felt something stirring under her bottom. So the girl jumped out of Kitahara Sosuke's embrace, wrapped herself in the blanket, and refused to look at him anymore.

No way! I just did that. If I keep doing it, I'll die! Nii-san is a beast!

"Aren't you going to blow-dry your hair?"

Kitahara Sosuke pulled back a corner of the blanket, revealing the girl's still damp black hair.

"Stop blowing! Now you'd better get out of here!"

Marina, like a frightened little animal, slapped away the other person's hand and wrapped herself back in the darkness.

"Alright, I won't blow it then." Kitahara Sosuke patted Marina's back through the blanket. "Be careful not to catch a cold."

"Okay, goodnight, Nii-san!"

Chapter Ninety-Nine: Climbing Through the Window at Midnight

The quiet of the night is when a person is most prone to overthinking, especially a girl like Marina.

Marina was well past her usual bedtime, but she wasn't sleepy at all. As soon as she closed her eyes, the scene from that time would appear in her mind.

"Ugh, I can't take it anymore, Nissan is so good at making me suffer..."

Marina covered her burning face, forcing herself to forget the images in her mind, but the more she tried, the more those images kept surfacing from her memory.

Just then, Marina suddenly heard something knocking on her bedroom window. Curious, she pulled back the curtains and looked outside. Why would someone knock on her window when she was in her own home?

"Nissan!"

Marina looked at Kitahara Sousuke, who was waving at her from outside the window, with some surprise, and exclaimed in delight.

Without hesitation, the girl opened the window and pulled the other person in. This was the second floor! She didn't know how Nissan had climbed up there; it looked so dangerous.

Good evening, Nana-chan.

Kitahara Sosuke climbed in through the window and looked at the girl's surprised face in the moonlight.

"Nissan, what are you doing? Why are you climbing out the window?"

Marina muttered a soft complaint, but her tone betrayed her shyness and joy. Why was her brother-in-law coming to see her so late? Was it because he cared about her? Or…?

"I wanted to see if you were asleep, but it was a bit difficult to get to your side by going around Ellie's door, so I had to climb through the window."

Kitahara Sosuke chuckled and scratched his head. Climbing two floors was nothing to him right now. He was just a little worried about Marina's condition, after all, a girl experiencing forbidden fruit for the first time is at her most sensitive.

Although Marina didn't say much that evening, you could still see the girl's hesitation and worry.

"I...I can't sleep..."

Marina said somewhat shyly.

"What a coincidence! I had a voice in my room saying that cute Nana-chan needs my help, so I rushed over right away."

Kitahara Sosuke sat down on Marina's bedside, then patted the spot next to him, gesturing for the girl to sit down as well.

"I'm not a child anymore. You can only fool Airi with things like that, Nii-san."

Marina hesitated for a moment, but then obediently sat down next to Kitahara Sousuke. As soon as she sat down, a pair of large hands pulled her onto their laps.

"I can't sleep either. How about I sleep with Marina? That way we can chat in bed."

"No, no... Nii-san, I haven't recovered yet, it can't be today..."

Marina struggled a little in a panic; she definitely couldn't let this happen again today.

"What's going on in your little head?" Kitahara Sosuke chuckled and playfully pinched Marina's delicate nose. "It's just sleeping together, but I sense you're not in a good mood."

"Really just sleeping?"

Marina looked at the other person with a puzzled expression.

"Really, just like when I was a kid, I did nothing."

Kitahara Sosuke nodded. After all, Marina's figure was truly amazing, almost unmatched among her peers. However, he wasn't about to be a beast; it wouldn't be good to leave the girl with lasting trauma.

"Then, Nisan, you have to hold me while I sleep, but you can't do anything else!"

Marina smiled, suddenly hugged the other person's neck, and rolled over, pulling Kitahara Sousuke down onto the bed.

"So, do you want to chat a little longer, or go to sleep now?"

Kitahara Sosuke covered the two of them with the blankets, then put his head on the pillow, and used his arm as Marina's pillow, while placing his other hand properly on the girl's waist.

Even through my pajamas, I could still feel the fullness pressing against my chest.

"Let's chat a little longer. It's been a long time since I've had a conversation like this with Nii-san."

Marina rubbed her cheek against Kitahara Sosuke's clothes like a kitten; they smelled like her.

"Okay, let's chat a little longer then."

"Nisan, do you have a girlfriend at school? You seem to be quite familiar with this today..."

Marina asked somewhat embarrassedly, "Nii-san is not only skilled in that area, but he also seems to know exactly how to pose comfortably in the bathroom..."

Is it true what they say about girls having a sixth sense? She actually asked the crucial question without even asking it casually.

"No, Nii-san, I'm still a pitiful single dog. This is the first time I've even slept with a girl at night."

Kitahara Sosuke felt that what he said probably wasn't a lie. The night he spent at Hoshizuki's house shouldn't count, right? He was being held by someone else, so it definitely didn't count!

"Oh, so how does Nii-san know so many ways to torment people?"

Truth is relentlessly pursued.

"Learned from doujinshi and anime? Anyway, guys always seem to have a knack for some weird things on their own."

Kitahara Sosuke simply said that Marina was so obedient that she definitely wouldn't go around spreading rumors.

"Okay, okay, don't bring this up anymore, or I won't be able to hold back."

Kitahara Sosuke straightened his body in a threatening manner, startling the girl so much that she forgot all her previous questions.

"I... I won't ask anymore, Nissan, please let me go."

"It's so pitiful," Mari pleaded.

"Nana-chan is so cute, she must have a lot of admirers, right? So, is there a boy you like at school?"

"I have received a lot of love letters..."

Marina nodded. She did have a crush on a guy before, and if he continued to pursue her, she might have agreed to date him.

But after today, even the last vestige of Masato in my heart has been completely taken over by Nissan. How could I possibly accept another boy's confession?

"It seems like you have someone you like?"

Kitahara Sousuke joked.

"No, that's not it. Nisan, that's so irresponsible of you to say. Are you looking down on me?"

Marina looked like she was about to cry, which was heartbreaking.

"How could that be? I like Marina the most. Why don't you marry me after Marina graduates from high school?"

Kitahara Sosuke smiled and patted the girl's pink back.

"No way. So I'll just be Nissan's sister."

Marina looked up and smiled slyly, finally speaking her mind, "Anyway, no matter how many girlfriends Nii-san has, they'll all break up eventually, but if I'm his little sister, I can be with Nii-san forever."

"But if I marry another woman, I'll have to move out, right?"

Kitahara Sousuke said with difficulty.

"Then please ask Nisan to find a girlfriend who is willing to live with Marina, otherwise Marina will not agree to Nisan dating her."

"Marina said coquettishly."

"Okay, okay, I promise to take care of Marina for the rest of my life, no matter if we get married or not."

"Hehe, let's pinky swear..."

As for the agreement that it would only be for sleeping, Kitahara Sosuke ultimately failed to keep his word, after all, Marina's chubby figure was just too amazing.

"The stock stock is high!"

Kitahara Sousuke thought to himself as he chewed on a piece of bread.

Chapter 100 Dude, you're not good enough!

The women's bicycle seats are very low, especially for petite women like Eriri who have adjustable seats. Kitahara Sousuke got up early and rode the bicycle he had left in the shopping street last weekend all the way back to school.

To be honest, it was very tough.

Even so, Kitahara Sosuke still didn't dare to touch the seat height that Eriri had adjusted. He could already imagine Eriri sitting in the seat he had adjusted, her feet dangling in the air, unable to reach the footrests, and how frustrated she would be.

The twin ponytail whirlwind felt like a tickle when it hit my body, but the little tiger teeth biting my arm really hurt. I don't want to relive that experience a second time.

It's best not to move around too much.

Kitahara Sousuke parked Eriri's car in a corner of the bike shed and stretched his stiff legs, feeling as if he had just done some weight training.

The morning sunlight shone on the synthetic track of the Toyonosaki Private School playground, reflecting scattered light as members of several sports clubs began their daily morning run training.

Most of the members of the basketball and soccer clubs are boys. Wearing short sleeves and shorts, they shout loud slogans and freely express their youth in the morning air.

Over by the sprint team, several girls, their clothes fluttering, revealed healthy, tanned thighs and faintly defined abs, attracting the attention of many male students who had just entered the school.
