The Multiversal Travel System

The soft sound of a sliding door and a female voice murmuring slowly pulled me out of unconsciousness. My body felt strangely light, as if every fiber of my muscles had regenerated and strengthened. Even with my blurred vision, I perceived a sweet and familiar aroma filling my senses. This wasn't the smell of my apartment.

I blinked several times, trying to adjust my sight to the dim light filtering through the curtains. I was lying on a comfortable futon, covered with a soft blanket. The room was tidy and simple, with a cozy atmosphere that contrasted with my own home. That was when I noticed the figure sitting beside me.

—Well, you finally wake up —Natsumi said with a half-smile, crossing her arms.

Her golden hair fell in soft waves over her shoulders, and her blue eyes shone with a mix of concern and relief. She was still wearing her training outfit, which indicated that she hadn't had time to change since finding me.

—What… happened? —I asked in a hoarse voice, struggling to sit up.

—I found you passed out in your apartment —she explained seriously—. Your chakra was completely out of control, as if it was about to explode. I couldn't just leave you there, so I brought you to my house and stabilized your energy with my own chakra.

I frowned, processing her words. It must have been the effect of consuming the God Tree Fruit. Although the system had mitigated the risks, my body still had to adapt to the overwhelming amount of power merging with my being.

—Thank you, Natsumi —I said sincerely, looking into her eyes.

She sighed, relaxing her shoulders.

—You don't have to thank me… But you better explain what the hell you did to your chakra and what's going on with your body. —Her gaze intensified, waiting for answers.

"My body?" I thought, confused.

At that moment, a notification resonated in my mind.

[System: Special Mission Unlocked]

[Strengthening the Bond]

Objective: Deepen your relationship with Natsumi and build a genuine bond of trust with her.Reward: 10,000 PS + Special Ability depending on relationship development.Failure: Loss of future opportunities to strengthen the bond.

I felt a mix of excitement and surprise. This was the perfect moment to get closer to her in a meaningful way. Taking a deep breath, I decided to be honest—at least partially.

—What happened to me… is complicated —I said, choosing my words carefully—. But I can assure you that I'm on a path that will make me much stronger than I am now. Though it also carries risks.

Natsumi frowned but didn't interrupt me. She just observed me in silence, evaluating my words.

—Don't think I'm recklessly throwing myself into danger —I continued—. I'm learning to control this power. But if you're worried… I'm sorry.

She seemed surprised by my sincerity. Then, she sighed, and her expression softened slightly.

—Idiot… If you get into trouble, at least let me know —she said in a more relaxed tone, though still with some reproach—. If something happens to you, it'll be a pain to pick you up off the floor again.

I chuckled softly, relieved. Maybe, just maybe, this was the beginning of something much more interesting between us…

—By the way… your appearance has changed —she suddenly said, blushing noticeably.

—My appearance? —I repeated, puzzled, before getting up and walking to the mirror in Natsumi's room.

Seeing my reflection, I could only think of one thing…

"I look absolutely magnificent."

(Current Appearance)

My horns were larger than any Otsutsuki seen before, signifying immense potential. My hair was longer and silkier, my skin had a slightly ethereal glow, and my physique had improved even further, making me taller and more sculpted.

—Natsumi… —I said, turning toward her—. I think I have fully awakened my clan's genes.

She watched me in silence, her face still slightly flushed.

—By the way, would you like to go on a date with me as a way to thank you for taking care of me?

[Relationship with Natsumi +5]

—W-With me? —she repeated, confused, as her blush deepened.

I nodded with a smile.

—Yes. You're an incredible person… kind, reliable, strong, and, on top of that, very beautiful.

She lowered her gaze, biting her lip, as if hesitating to answer.

—But… I'm a demon. I don't deserve love —she whispered almost inaudibly.

My eyes widened in surprise.

—Why would you say that? You're not a demon. You're the most charming girl I've ever met.

She shook her head, her eyes filling with tears.

—That's what they always told me… Even when I was in Konoha, I liked a classmate. One day, I asked him out… and he laughed at me. He said he would never go out with a "demon" like me… —As she spoke, tears began falling down her face.

A feeling of anger surged within me.

—Those idiots didn't see how amazing you are. They don't know how lucky they would be to have you by their side.

She looked up at me, her eyes red and glistening.

—Do you… really believe all that about me?

I smiled softly.

—Of course. And if you want, I can prove it to you.

—I don't believe you… —she murmured, wiping her tears—. S-Show me…

Without hesitation, I stepped closer to her and slightly bent down to her level. With my new transformation, I had grown to 1.90 meters. Then, without wavering, I kissed her lips.

Natsumi froze for a moment, surprised, but when she felt that my kiss carried no lust—only genuine love—her body relaxed. Slowly, she closed her eyes and returned the kiss.

When we parted, she started crying again, but this time, out of happiness.

[Relationship with Natsumi +15][Relationship with Natsumi: Max]

I smiled at her expression, knowing at that moment… that I had taken a big step in our relationship.

She wrapped her arms around my neck and kissed me back. For five minutes, we surrendered to the moment until the lack of air forced us to separate.

—"Do you believe me now?" —I asked with a big smile.

Natsumi didn't answer with words. Instead, she kissed me again, this time pouring all her love into it. Of course, I responded in kind.

When we finally pulled away, I looked at her intently.

—"There's only one thing left to say… Natsumi Uzumaki, will you be my girlfriend?"

Her face turned even redder, but her answer was clear and full of emotion.

—"Of course!" —she exclaimed before kissing me again.

After another five minutes, we separated once more, both wearing smiles of happiness.

—"Well, sweetheart, how about we train as we planned? Then, I'll take you on a date."

—"Alright," —she said with a big smile.

—"Let's go then," —I replied, effortlessly lifting her by the waist, making her let out a playful laugh.

As we headed to the training field, the system's voice echoed in my mind.

"Why do I have almost all my Dōjutsus locked in the system?"

[System: "During the assimilation of the fruit, I had to lock them to prevent you from suffering further damage."]

"Well, I guess it was for the greater good. Besides, these Dōjutsus will level up the more I use them or improve my control over them."

[System: "You are correct, Host."]

"Well, that's an advantage."

"We've arrived," Natsumi told me with a big smile.

"Alright, shall we start, dear?" I said with a smile.

"Of course!" she replied.
