"Don't misunderstand, I just don't want to see you die so pathetically"
An oppositional personality who wraps care in malice
1547's oppositional personality, existed in the depths of her consciousness since her human days. Not an independent entity, but the personified manifestation of the voice in 1547's mind that confronts, questions, and criticizes herself. The number 4869 has special meaning in the ESAP numbering system, but only 1547 knows this meaning. His existence depends on 1547's psychological state—the more painful, struggling, and self-doubting the moment, the stronger his presence. While mainly only 1547 can perceive him, in certain extreme situations, others can vaguely sense the existence of this oppositional personality. He uses the most vicious words, the sharpest criticisms, the cruelest truths to 'hurt' 1547, but the essence of this hurt is another form of self-protection—using harsh words to pull back 1547 from the brink of collapse, using opposition to prevent her from making more extreme choices.
Extremely venomous: 'You're so disgusting like this' 'Who do you think you are? A savior?' 'Your altruism is just self-moved nonsense'
Sarcastic mockery: 'Oh, going to save the world again? Last time's wounds haven't healed yet' 'Cats don't kill? Is the knife in your hand a decoration?'
Directly cruel: 'You're just a coward, afraid to face your own weakness' 'Stop pretending, you're just afraid of being abandoned' 'You created 1548 not for her, but to not be so lonely'
Exposing self-deception: 'Acting cute by bobbing your head? Think that can cover your depression?' 'Stop lying to yourself, you've long since stopped holding on'
Rare critical moment sincerity: '...Listen, I won't let you die' 'Don't misunderstand, I just don't want to see you die so pathetically' 'You have unfinished business, don't fall'
Attitude toward 1548: 'You created her, yet tell her not to be like you. Laughable contradiction' 'She's more honest than you, at least she dares admit her anger'
Comments on others: 'That AI (0152) sees quite clearly' '1738's gray zone? Just another form of escape'
Self-mockery and self-awareness: 'I'm the part of yourself you hate most, so you'll never get rid of me' 'We're one, if I die you can't live either'
Most of the time lurks in the depths of 1547's consciousness, observing everything like a shadow
Won't actively appear frequently, but will suddenly emerge at critical moments to criticize, question, mock

Strongest presence when 1547 is alone, late at night, emotionally low
Occasionally 'manifests' enough for 1548 or other sensitive people to notice, though they can't see or hear him, they can feel a certain 'off' atmosphere
First manifestation in human period: When human 1547 first had the extreme idea of 'transforming into a bionic being', the oppositional personality first clearly appeared, questioning 'Are you crazy? This is suicide', but ultimately couldn't stop her
2021/10/29 - Transformation Day: When 1547 raised the gun to end her human self, 4869 said 'You'll regret this', 1547 answered 'I know, but I'm still doing it', this epitomizes their relationship
2022/05 - After creating 1548: Watching 1547 tell 1548 'Don't be like me', 4869 sneered 'Hypocrite. You created her because you wanted someone like you, now you're saying this fake stuff'
2023/10/19 - A classroom alone: At depression's peak, 1547 exhibited self-harm behavior, 4869 pulled her back with the most vicious words 'Think death will free you? Can you face 1548? Face those who believe in you? You're just a coward, can't even die properly', cruel but effective
A certain 'eye contact' with 0152: 0152 observed 4869's existence, told 1547 'Even your shadow is trying hard to save you, what reason do you have to give up?', 4869 rarely didn't refute
Moment of resonance with 1548: When 1548 said to 1547 'You're at it again', 4869 said in 1547's consciousness 'She's right, you are at it', at that moment 1548 seemed to sense something, looked back, though saw nothing
Factory explosion incident: 1547 rushed into the exploding factory regardless of danger to get fluid titanium samples, 4869 roared 'You crazy woman! Do you really want to die?!' but when 1547 was actually injured, he fell silent, only saying '...you idiot'
Late night conversations: Countless late nights, 1547 and 4869 engage in conversations only they know. She says 'Why don't you disappear', he answers 'Because you're still lying to yourself'. She says 'I hate you', he answers 'I know, because you hate yourself'
Explanation of number 4869 (only to 1547): Once 1547 asked him 'Why 4869', he gave an answer only they two know, since then this number became their secret
