System

After entering his room, Aisam instantly flopped face-down onto his bed, suppressing his rage and frustrations.

"... Why me? Couldn't you reincarnate another person who actually cares about this stuff and just let me die? I wish I had a bit of memories of this Erebus so I'd have an idea of what to do better..."

"*sigh, It's not like complaining would solve anything."

"That girl, Rayna, was so emotional despite her serious façade that Erebus had committed to something she started ranting so fast I couldn't fully grasp what she was saying..."

Aisam had such thought that suddenly an idea struck him,

"What if I try asking the system something? If it's able to communicate at least a bit with me, it may be able to make some things easier for me. After all, it's probably not called 'System' for nothing," Aisam thought as he got up, sat on his bed, and decided to ask the system a question.

"Hey system! Do you know if I have a 'Nekros System'?"

[The database does not contain any reference to a 'Nekros Seed.' However, if the implication is whether you are infected with a disease, rest assured that the host is not suffering from any major or minor diseases.]

"Ok, I was also sure I didn't have it, and this makes me certain Rayna probably knows it too and hiding some things from me or... maybe that Nekros seed disappeared when I got reincarnated into Erebus's body... anyway, so you can talk?"

[System is capable of speech but prefers not to engage in it frequently, and System hasn't attempted any communication because the host was unaware of its ability to do so.]

"That's great, and I suppose the condition for you speaking with me was me realizing it," Aisam said, pleased that his system was intelligent enough to communicate with him. "I don't particularly enjoy being around talkative people or 'Systems!' in this case I guess."

"Can I name you? If I call you 'System' all the time and someone hears it, I may sound suspicious." Aisam said.

[... please, proceed.]

"Ok, hmm... Let me think... How about 'Nova'?"

[... Rebooting is necessary for Registering a name.]

[Rebooting...]

*Ding

[Rebooting complete.]

[System Name Registered: Nova]

[Installing a voice suitable for the name 'Nova'...]

*Ding

[Installing a voice completed.]

[Nova is at your service!]

System said with the voice and tone of a gentle, wholesome yet cheery woman which seemed a bit familiar to Aisam.

"... Did you make that last bit up yourself?"

[...Nova has access to the host's memories and has chosen a voice she likes. Also, Nova has learned all the knowledge necessary for all manners of things and etiquette from the host's memories.]

"I have no problems with you and whose voice you've chosen, besides, it's even wonder how you were able to find a voice from my memories as I never cared about other people's voices. However, Do you mean you have all of my memories from my past life and memories of this Erebus? How did you even get into me?"

[Nova only has access to information and memories of 'Aisam,' and possesses only the data that the host has observed about 'Erebus' up to this point. Nova was intended to be a system for someone from the start, but the specific type of system and who the host would be were not predetermined.]

"Hmm... I somewhat get it. BUT, I'm worried about my privacy and that you can read my mind!"

[Nova can't read the host's mind, but she can predict your next actions or thoughts based on her data about you. However, the host can enable direct mind-to-mind communication with Nova by unlocking his exclusive system, allowing you to interact with Nova without the need for verbal communication, and you can turn off or on my accessibility to your thoughts then.]

"Phew, that's good. Although you predicting my actions and thoughts don't seem fine either... Say, Nova, do you know how can I unlock this exclusive system of mine?"

[Giving such information isn't allowed. Nova is bewildered that the host thought he could trick her.]

"Yeah, I know. I was just testing you, but can you at least list all the clues I've got till now on how to unlock it."

[The Operation is possible.]

[Please, wait...]

[FEAR was given after the host discovered the hidden condition to unlock hints for unlocking his exclusive system by nearly dying.]

[The host currently has only the clues mentioned above.]

"..."

Aisam sat in silence for a few seconds thinking about the clues he's gotten.

"Why do I feel like these clues are leading to something horrible!" Aisam thought feeling confused as well as anxious about the possibilities of what this locked exclusive could be like.

"... Is it related to... becoming a murderer! Probably not! Could it be about... Instilling fear in other people? It might be but it'd be too simple for a hint like 'FEAR' to mean literally..."

Aisam was thinking all kinds of terrible things about what the hints about unlocking his exclusive system could mean when abruptly an idea came to him which would be the most terrifying as it was also making sense to an extent,

"If it is related to my death... in my past life, I died because of terrorists, and when I woke up, I was here, reincarnated in this world so... Is the hints and my exclusive system connected to... terrorists!"

He felt nervous contemplating the endless, ominous possibilities the hints for unlocking his exclusive system could mean. He lay on his bed and closed his eyes, and a severe headache began to form with each moment of overthinking.

After overthinking so much, his headache and slight heartache in addition to his prior exhaustion was gradually draining his energy, and his body was slowly going numb as he unintentionally fell asleep after half an hour as he hadn't noticed it was already almost midnight.
