She hasn't matured yet.

Chapter 48

Title: She hasn't matured yet.

[Cringe Warning(?)]

….

–General Pov–

Amon released a cough and acted like nothing ever happened, while Robin released an 'unnoticed' sigh.

"So, Miss… All~ Sunday. Ugh, why the fuck is your name too long, use another code name." Amon said in a grumpy voice as he leaned back on his chair.

Robin stayed indifferent at his words and opened her mouth. "You can call me… Robin if you want." She replied after much delay.

Amon was genuinely surprised hearing her, as he smirked internally. This is not the first time he asked her for a new name, but she never changed them before… Yet, now she revealed her real name, albeit still under disguise.

'The current Robin is only 19 years old… She hasn't achieved the maturity that she will have 10 years later.' Amon thought, trying to calculate why she acted this way.

Soon he smiled. "Oh? Like the bird Robin?" Amon asked with an impressed tone. "Such a short and beautiful codename. Then call me Gabriel if you like, I will go with that nickname." He said as he leaned back.

Hearing Amon's tone, Robin giggled. "No, I'm very fine with Lucifer."

"Really, just 'Lucifer'?" He jumped forward. "Thank you."

"No, I mean Mister–"

"I get it, don't be shy," Amon cut her, as he slopped forward and rested his chin on the table, while he started to drink juice from a long straw. "I quite mind you adding Mister… I'm just 13 years old, after all! It's cringe when you add 'Mister' before my name."

Robin blinked… just blinked. 'What… 13 years old? He is 170cm tall. So he must be joking…?'

Soon, she giggled. "Fu fu fu. My my, I knew girls tend to lie about their age, but it's the case for Mist–Lucifer too?" She corrected her words at the last moment, as she felt the gaze from him.

Amon smirked internally.

"Who knows really… Nobody asked you to believe it, anyway…" He said as he looked away, with his face becoming a little red.

A smile bloomed in Robin's face involuntarily as she looked at his averted gaze. 'Pfft, he's so cute. Ahh, I want to tease hi–NO!' Suddenly her eyes grew. 'What am I thinking? This is… NO. Just no… Fuuuh, I need some fresh air.'

Robin, being still very young in this timeline, wasn't mature like the Robin in canon. For that reason, her trust issues were at their peak, however, it was something Amon was completely aware of.

Robin got up from her seat, with her face becoming motionless. "Mister Lucifer, I remember I have something to do, I will take my leave now."

She said with a bow and turned around.

"Oh… okay." Amon looked ahead and waved his hands, as Robin left through the door. Yet, he was laughing internally. 'Is this stage 3 denial I see? Damn, and it's only been around 4 months since she's been here. Well… she is still inexperienced , I will form her as I like.'

….

A few seconds later, Amon sighed loudly in 'disappointment'.

"She left, huh…" He mumbled. "I needed someone to apply some medicine on my wings… It's hard to do it myself, after all." Amon released a chuckle… a mocking chuckle. "Well, it was too much of me to expect her to do it, hahaha…."

He released a long sigh and sloped back on his chair. "Who am I to her anyway, just a boss in the end… I will just do it myself–"

*CREAK!*

Suddenly, Robin entered with a straight face. "M...Mister Lucifer," She didn't even realize her shutter. "I suddenly remembered, I'm kind of free and I'd like to apply medicine to your… Wings." She didn't flinch at all, as she said those words while shuttering.

Amon just looked at her with a frozen expression. "Oh–you haven't… left? Haha, did you… hear anything?" Amon said as his face turned full red. Being able to blush at will is a blessing.

Amon obviously knew she would return since she didn't straight up leave and was halted on the other side of the door, as he was suppressing his grin currently.

'Uff... she didn't even realize how robotic her words sounded just now.' Amon thought with an 'achieved' smile in his mind. 'Feels good when things are going according to what I want.'

Robin just looked at him with strangeness sweeping within her eyes. Just now behind the door, when she was preparing to leave, she recalled his words from 2 days ago, in Alabasta.

######

2 days ago, she regained consciousness before many others did, though Amon 'didn't' realize. However, she just kept pretending because she felt Amon's hands stroking her head, while he was talking to himself.

'This is strange…' Robin thought. 'So he's finally coming after me too? While I'm 'unconscious' too… Disgusting. And here I thought he saved my life out of–Sigh, why are people like this?'

Before Robin could think anything else, she felt a hand on her head.

"Would you look at this big girl sleeping like a little princess…" Robin felt his hands stroking her cheeks, rendering her stunned. However, she felt his hands removing her cheeks as she heard a… sad sigh?

"Fuu, I almost mixed you up huh, Miss All Sunday." He said as Robin stayed silent. "Just how much do you resemble my little sister?"

She was caught off guard by his words, but she was supposed to be unconscious, so she held herself back.

"Haha, now that I think about it, I kinda miss her, my little sis I mean." He said again, putting his hands on her head. "She's been alone up there, in the sky for 2 years now. Maybe she is lonely being alone… One day, soon enough, maybe, I should also go up there, haha… Will anyone miss me from down here? I don't know."

His hands stopped stroking her hair. "Some may, but some may not."

"Forgive me, Miss all Sunday… I almost used you as a substitute. Though I still have hope to make you into my big sister if you'd like… Hahaha…. Fuck."

While Robin was shocked, Amon's self-talking was cut short as he noticed the marine fleets arrive.

######

As Robin recalled his words, she gulped inwardly. 'What did he mean by 'Sky' and 'Lonely'? Is his sister dead?' She thought, looking at the surprised face of Amon. The current Robin had no clue of the existence of Sky islands.

'Actually, it makes perfect sense if I think it through… But most importantly, his words also sounded like a will before death…' She thought as he looked at his large red and innocent eyes looking at her.

'He misses his sister… So he wants to meet her. But since she's dead, he can only do it by committing the same thing…' Robin thought as she reached her conclusion.

'Then it also makes sense why he never tried to pursue me before, and only stared at me now and then… It's because he saw his sister in me!' Robin thought. 'J-Just how much do I resemble that girl?'

While thinking this, she looked at Amon with her eyes wide.

Amon could predict her thoughts to some extent. 'This won't work obviously. People don't like being A substitute for someone else.' He predicted her next thoughts. 'I already said sorry when she was 'sleeping' though… I'm sure she took that into account.'

Seeing Amon looking at him with confusion, a strange… feeling started to bloom in her heart. 'Then… if I stay with him, will he treat me as his sister? Will he ignore his suicidal thoughts? Will I… find another family?! Will I get to live my Life?!?! WILL I BE LOVED AGA–NO! Get a hold of yourself ROBIN!'

Robin bit her lips and shook her head rapidly. 'I don't have the luxury to play 'sister'. I also don't have the luxury to become a substitute for someone else. Things will change… what if he finds someone who resembles his sister more than I do? What if… his sister isn't even dead?... But he also said… He wants me to be his bi-AHHG!'

Trying her best to think things through, her head started to hurt. A few minutes passed, but it felt like an eternity to her. Soon, Robin released a calm breath.

The past 2 days, she's been in a dilemma. A complete dilemma, but she finally reached her conclusion. 'Grandline's danger and protection from a stranger made me rely too much on him. He, in the end, is just an ant before the World Government.' She thought as she smiled.

Seeing her smile, Amon also smiled. 'Haha, look at her. She's so easy. Dancing in my palm!... Ahhh, I want to continue doing this, but she needs emotional support first.'

While Amon was 'observing' all her thoughts, Robin was there with a 'calm' mindset. 'I will leave the Grandline. I'm grateful for my days here, days with him, I really am. So I will do him a favor and leave the Grandline soon… Or things will be very messed up.' Robin thought as she released her usual teasing smile.

"Ahh, Mister Lucifer, I meant to say, I saw it, your wings still injured when I entered the room… So, I was saying, I can help you put medicine if you'd like."

She said as Amon smiled brightly.

"Oh, really?! Thank you~ s—ROBIN!" Amon said in exhilaration.

Robin ignored his shutter and came close to him, while Amon kept smiling.

….

Currently, Amon was grinning sadistically in his head. 2 days ago, he obviously said those words knowing she was awake. He expected some kind of outcome, but never did he think it would work this well.

He knew something important, something he's been using all his life. 'Hope', 'Pity' and 'Guilt'. 3 words, hope, pity, and guilt. 'Using pity to lure victims always works, doesn't it? Then there is hope, using it people will act out of character. But guilt… it's hard to create that type of emotion inside someone…' Amon thought.

Robin was behind him, applying the medicine.

'She is in denial, she can't accept being a substitute. Well, I did add more words, and as time will pass she will realize things can be changed. Once she is attached to me for real, even being a slave won't hurt her, let alone a substitute. That time she will be more than happy to be a big sister....' Amon thought.

'Hmm, her emotions are telling me that she wants to leave?'

Amon then went full calculating mode, trying to think of the best outcome of all things. 'Though there are benefits if she leaves… those are shit. So no, you can't leave. The moment you stepped onto Whiskey Peak, you were under the gaze of the hawk, you were a prey from the beginning, Nico Robin.' Amon thought with a cold smile in his mind.

Amon again started to calculate things, the actions he needs to do to keep her here at her own will.

'First, I need to show her love and care, more than what I'm doing until now. I will also have to let her know about the World Government and the Celestial Dragon. Though she does have a little knowledge on them, it is too measly.' Amon thought. 'I need her to, from her core, hate the world government, the ones who burned her home.'

Looking at her blue eyes, Amon was thinking what level of stupid she was. 'It's hard to believe why she didn't hate them in the canon timeline. Though I'd guess it's because of Aokiji. She was scared as shit of him, that she didn't even get the chance to hate them. However… I NEED her to hate the WG this time around, in this timeline she needs to be a ruthless bitch.'

It sounded hard to achieve, changing a person's whole life goal, yet Amon chuckled. 'If she was 28 like canon, then it would have been nigh-impossible to manipulate her as I wanted, so I would have rather killed her. But…. Luckily, she's just 19 and still hasn't matured like canon. I can do whatever I want with her weakened min–'

"Ugh! Be gentle!"

Amon flinched from the pain as Robin was applying the medicine.

Things were going forward, as smoothly as they should and could.

A/N: 😄 fuck. Anyway, we can see how Mc is fucking with Robin's head, where his emotion-sensing powers are playing a big role.
