MULTIVERSE: THE LUST SYSTEM Chapter 25, a Naruto + Highschool of the Dead Crossover fanfic

"It can't be..."

Rei's face was deathly pale, her eyes wide in disbelief.

"Rei, do you believe what I said?" Hisashi asked in a low voice, trying not to alarm her further.

"How could I not believe!?" She shouted, her voice trembling. "No matter how unreal it is, the way you told it was so vivid, just like everything that happened with Shido-sensei and his cult." She spat in disgust when mentioning his name. "Or even about the secret number I have from my father, among other things... Hearing all this, as hard as it is to believe, I know you wouldn't make something like this up just to scare me."

"Rei, calm down a bit first." Hisashi held her shoulders, which were shaking intensely, while tears already began to stream from her eyes.

"How could I calm down?" She looked at him.

He thought of a situation where the boy kisses the girl to make her stop crying, but decided not to do that.

In the softest voice possible, he said: "Rei, listen to me. I know it's scary, I was scared too when I woke up from this nightmare, maybe even more scared than you, since I experienced everything in a realistic dream. But, then I realized that being scared and panicking won't solve anything. For now, I want to try my best to save those I love."

She nodded, listening intently, but it was impossible that just because he said that, she would stop being afraid.

Sighing, Hisashi continued: "Now, you need to think about what to do with this information. As I said, what made me mainly believe this is real are my special powers, like becoming invisible, or even you and I becoming stronger by having sex. And it seems that, indirectly, you also got stronger. Did you notice?"

"I got stronger?" These words seemed to calm her a bit, like a ray of hope.

"Yes, test it yourself. Try breaking a broom handle with your hands or lifting something heavy." Hisashi suggested with an encouraging smile.

She didn't do it immediately. Instead, she clutched his shirt tightly, burying her face in his chest.

In doing so, she seemed to find an unexpected peace, more effective than any calming tea.

Minutes later, Rei took a deep breath and sighed. Standing up all at once and raising a fist high, she shouted: "Alright! I will do this!"

A bit surprised, Hisashi, who saw her act like that, felt a bit better afterward. It was better to see her like that than sad.

"What do you think, Hisashi? Should I try lifting this sofa?" She asked, looking in the direction of the sofa where he was sitting.

Getting off the sofa, he said: "You can start by trying that, or even try lifting me. It's safer."

"Good idea."

Rei went to him, wrapped him in a hug, and with wide eyes, saw that she managed to lift him with incredible ease. She spun him in her arms, while murmuring: "How could I have gotten so strong without even noticing?"

"Put me down first." Hisashi said.

"Oh, yes, right." She put him down and then stood before him, strangely a bit excited.

It even seemed that she would be sad after he told her about the zombie apocalypse, but in her own version, where he survived much longer instead of being killed right at the beginning...

"I asked myself that question too," he said. "After reflecting, I concluded that I was strengthened in a subtle and natural way, so pure that I didn't even notice. Seeing that you didn't notice your increase in strength made me think that subconsciously you weren't using all your strength because you believed you couldn't."

"I understand... Stopping to think about it, it makes sense," she nodded. Soon her eyes sparkled a little: "Then, if we have more sex, I will be strong enough to protect us; to protect my parents?"

"You're not wrong to think that way," Hisashi did not deny it.

"Then..." She started to blush, but not from embarrassment.

"Wait, Rei," Hisashi stopped her: "Although it's a tempting proposal, your parents should be back soon and, honestly, I want to go back to talk to Tsuki-nee and tell her about this too."

"... You're right," she sighed, feeling sad as she said: "It's a shame, but it seems there's no way around it. And, Hisashi, do you think I should tell my parents?"

"You can try, but the problem is..." Hisashi smiled ironically: "Would they believe it?"

"That..." Thinking about her parents' possible reactions to telling them about a potential catastrophe where billions of people would die in a damned tragedy of the dead coming back to life and turning the living into zombies through bites... It's indeed unreal to think they would simply believe it.

Holding his shirt sleeve, she looked with an incredibly pitiful expression: "Hisashi... How about you stay and help me tell them? If it's you, I'm sure it will be at least more convincing."

"Although I think you're giving me too much credit, I'll do it, but can it be tomorrow?"

Hisashi suggested: "Today, you tell them you had a strange dream, say it was something you dreamed and that the dead came back to life, etc. Tell fragments of what I told you, with you as the protagonist of the dream."

She nodded, listening attentively.

He continued: "Tomorrow, I'll come back with you and we'll tell them together that I also had the same dream, but I'll give more detailed explanations. We'll do it in a way as if we both had similar dreams but with our own perspectives, how about that?"

After hearing this, her eyes sparkled a little: "Yes, this might work more convincingly! Thank you, Hisashi, for thinking of such a plan!"

When she jumped into his arms, he held her, soon receiving several kisses on his face from her.

When Hisashi arrived home, Tsuki had already made dinner and was waiting for him.

After they ate, he said they needed to talk. Curious, she waited for him to speak, only for silence to linger in the air.

'Why is he looking at me so hungrily again... It can't be what I'm thinking, right?'

Tsuki felt that the silence was mainly due to her little brother's hidden desires for her. She 'knew' he desired her, could feel his intense gaze that seemed to want to devour her.

'We can't, Hisashi, this is wrong!' She thought, resisting in her mind. 'We're siblings, we can't, we can't. And didn't you finally get your beautiful girlfriend to fall in love with you? Then why do you still desire me so ardently?' She shook her head in denial.

On the other hand, Hisashi, observing all this, was a little confused by her reaction, not knowing what she was thinking.
