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

Ellie listened with a pang of heartache to the sound of rushing water in her ears; it was water overflowing from the bathtub as the two of them moved around.

"Okay," Marina replied softly, then turned to Kitahara Sosuke with a pitiful look, "Nii-san, this can't go on like this..."

"I know...but..."

Kitahara Sosuke's voice was a little hoarse, his body was wet and slippery, and Marina in his arms was also plump. Any man would find it hard to resist in this situation!

Chapter Ninety-Seven: Not Now

"Yay, I'm done washing up, come in now."

Airi rinsed the soap off her body, then stood up and turned off the shower. She looked at Marina, who was huddled in Kitahara Sousuke's arms, with some confusion, but she didn't think much of it and assumed that the two of them were squeezing together to make room for her.

Without saying a word, Ellie walked briskly towards the bathtub.

"It's so crowded, I don't want to soak anymore. You two should come out soon after you've had your fill."

As she spoke, Ellie stood up, took off her pink bath towel hanging on the wall, wrapped it around herself, and walked out of the bathroom without looking back, muttering to herself as she went:

"We promised to grow up together, but Marina has secretly grown so big! Honestly, it ruins my mood for a bath! Damn it, when I develop, I'll grow big too..."

The girl grumbled as she went back to her bedroom to change into her pajamas and blow-dry her hair.

Once Airi's figure had completely disappeared from the bathroom, Kitahara Sosuke and Marina finally breathed a long sigh of relief. Kitahara Sosuke looked at his younger sister in his arms with a complicated expression, unsure of what to say.

The fact that the girl didn't cry, make a fuss, or resist, but instead tried to cover up the truth for him, sometimes already revealed her attitude. He could only tighten his grip on her arms again, hugging her tightly, as if trying to meld her into his body, attempting to give her some sense of security.

"Does it still hurt?"

Kitahara Sousuke hugged his larger-than-life sister's chubby body tightly, trying not to make any sudden movements, and asked her with some concern. To continue doing anything at this point would truly be worse than being an animal.

No girl wants to lose her virginity in a place like this, right? Seeing Marina biting her lip and enduring the pain, he felt a pang of sympathy.

"A little……"

Marina let out a wronged sound and gently moved her body. Another wave of tearing pain shot through her body, scaring the girl so much that she dared not move again.

"I'm sorry, Nana-chan, I..."

Kitahara Sousuke apologized softly, but before he could finish, the girl covered his lips with her hand. Marina blushed, mustered her courage, looked at Kitahara Sousuke, and gently shook her head.

"It's okay, Nissan... I'm willing."

Kitahara Sosuke stared blankly at her. His image was reflected in the girl's dark pupils, which were filled with indescribable emotions. If he didn't know what to do at this moment, he would really be an idiot.

Kitahara Sosuke suddenly picked her up, and with a gasp from the girl, turned Marina 180 degrees so that they were facing each other. Then he lowered his head and gently kissed the girl's pale lips.

"Seriously, how can taking a bath make you dizzy?"

Airi crossed her arms and looked at Marina, who was fast asleep on the bed. The girl's face still had a lingering flush, and her small, delicate nose emitted even breathing sounds.

She was startled when she saw Kitahara Sousuke carrying Marina, who was wrapped in a bath towel, out of the bathroom. Was it just because she'd been soaking in the bath for too long?

"You really didn't bully Marina, did you?"

Airi looked at Kitahara Sosuke with some confusion. For some reason, she felt like she had missed something important. However, when Marina was carried back to the bedroom in a princess carry, she was still wearing her swimsuit. She even helped Marina change into her pajamas. Could it really just be her imagination?

"She's probably been quite tired lately. It seems like she took a short nap in the bathroom just now, so she soaked for a bit too long."

Kitahara Sōsuke replied without batting an eye that he was indeed tired, but for other reasons.

"Seriously, it's not a hot spring, how could she make herself faint? Marina is so careless."

The two of them were surprisingly in agreement, so Airi could only suppress her slight doubts: "Then I'm going to soak for a while longer. You idiot Sosuke, you take care of Marina!"

"Okay, but I've already drained the water from the bathtub, so you'll have to prepare it yourself."

Kitahara Sousuke nodded.

"Huh? You idiot, Sosuke! That bath salts are expensive, and you just wasted them like that!"

Ellie stormed over and kicked the other person in the shin.

"I'll buy it for you later."

Kitahara Sosuke shrugged indifferently. After all, it was money he won in the lottery. As long as it wasn't wasted, he wasn't too harsh on Airi and Marina. Girls should be raised in comfort, right?

"real?!"

Airi cheered and jumped up to kiss Kitahara Sosuke on the cheek, then realized something was amiss—Marina was still in bed. She took two steps back shyly. "It's a promise, you can't go back on your word. I've already paid the payment..."

"I won't go back on my word." Kitahara Sosuke chuckled and patted the other's head. "Go on, keep your voice down, Marina needs to rest."

"Uh-huh."

Chapter Ninety-Eight: Pinky Promise

Kitahara Sosuke sat on the edge of the bed, gently touching Marina's sleeping face as if it were a precious treasure. The flush on the girl's face had gradually faded. As if sensing that someone was watching her, her thick eyelashes fluttered, and she opened her hazy eyes.

The girl blinked her beautiful eyes, and it took a long time for her to gradually regain her senses from her dazed state. When she saw that the person in front of her was Kitahara Sousuke, she seemed a little excited, but she quickly composed herself, leaving only a hint of shyness.

"Nissan..."

"Are you tired? Get some rest."

Kitahara Sosuke picked up a strand of black hair that was stuck to the girl's lips. The exercise in the bathroom just now seemed to have been a bit too intense for Marina, who rolled her eyes and lost consciousness halfway through.

"Mmm—Nisan, hug me!"

Marina nodded, hesitated for a moment, then stretched out her hands cutely towards Kitahara Sosuke, looking at him expectantly.

Kitahara Sosuke chuckled as he helped Marina up, gently embracing her soft, boneless body and patting her back lightly, as if soothing a child.

Why are you suddenly acting all cute and affectionate?

Kitahara Sosuke's nose was filled with the fragrance of the girl's hair, a delicate jasmine scent.

"Hehe, you really did it."

Marina snuggled against Kitahara Sousuke, feeling her brother's broad chest, and chuckled foolishly before revealing a sly smile: "Sometimes I wish I could act cute like Airi and act spoiled with you, Nii-san."

"Because you are usually too sensible, Ellie is more like a little child."

"Then I'll be as immature as Ellie from now on."

Marina joked that of course it was impossible; her personality wouldn't allow her to do something like Airi.

As she spoke, she broke free from Kitahara Sosuke's embrace, touched his face with both hands to examine it carefully, and then happily kissed Kitahara Sosuke on the chin.

"Ah, it's so great that my first time is with Nii-san!"

"Ah this..."

Kitahara Sousuke blushed slightly, feeling a little embarrassed. He did feel guilty about hurting his own sister, but since he had already done it, he should take responsibility for it.

Kitahara Sousuke stroked the girl's soft hair, which was still slightly damp from her recent shower.

"I was too impulsive; I shouldn't have been in that kind of place."

"How could that be? Nii-san is the best."

Marina smiled foolishly, looking like a completely different person from her usual gentle and generous self. She seemed more like the mischievous Airi. You could say they really are sisters.

But after the initial joy, Marina returned to her usual self, a hint of worry showing on her face as she immediately began to consider the future.

How am I supposed to explain this to my mom and Marina?

Siblings can't be together. If Mom and Ellie found out, they would be very sad, and she and her brother would eventually separate due to various pressures.

Didn't we hear news reports before about a brother and sister who did the same thing as Nii-san and got their legs broken by their father? Thankfully, Marina and Nii-san's father is dead, so Nii-san won't...

No, no, what am I thinking? Marina mentally gave herself a hard whack.

In short, even if Nisan doesn't have his legs broken, his mother might kick him out of the house in the future to prevent the same thing from happening again.

Such taboo things are not allowed, but I really, really like Nii-san. I have always liked him since I was a child. Although I gradually stopped saying things like "I want to marry Nii-san when I grow up" as I grew up, my feelings only became more and more precious with the passage of time.

After this, Marina finally understood her own feelings; she truly felt more than just familial affection for Nii-san.

what should I do?

Why not just be a younger sister? As long as I can stay with Nii-san, isn't the relationship the same?

She's the younger sister, and Nissan will definitely have girlfriends in the future, maybe more than one, but she can just be the younger sister. As long as she's the younger sister, she can always stay by Nissan's side.

After all, girlfriends can break up, but a sister will always be a sister.

Marina hesitated for a long time, biting her lip as if making a very difficult decision, before finally raising her head again to meet Kitahara Sousuke's gaze.

"Nisan, let's just keep this quiet and not tell anyone, okay?"

Truth begged.

"why?"

Kitahara Sousuke asked, somewhat puzzled.

"Because... anyway, Nisan, you're not allowed to tell anyone, or else I'll never talk to you again!"

Marina took advantage of her girlish arrogance and buried her head in Kitahara Sousuke's chest, becoming a coward.

"Mom can't tell, Ellie can't tell, nobody can tell!"

A muffled voice came from her arms. Kitahara Sosuke chuckled and patted her shoulder: "Okay, I know, I won't tell anyone."

"I only want to be Nissan's sister, I don't care about anything else."

"Brothers and sisters wouldn't do such a thing."

Kitahara Sousuke joked with a smile.

"Nii-san is lying. When I was cleaning his bedroom, I saw a lot of doujinshi. Nii-san was clearly looking at those kinds of doujinshi. Maybe Nii-san has had feelings for me and Airi for a long time..."

Marina looked up and glared at the other person.

"That's something a friend left with me temporarily..."
