Becoming A Nameless Character In A Chaotic World

It's your usual reincarnation into a fiction world, be it yours or others. But do you know what's make my reincarnation different? It's that I fvcked up in the beginning! Game! Comic! and Novel! I have created them all from when I was a college students until I died a virgin. When three of my works combined into one, boom! A chaotic world is born. And I, Rey Pale, has been reincarnated in that world which is already doomed for destruction! But it's okay... Because I'll be the main character! ...or so I thought. In reality, I'm just a nameless character. ...or so I thought. With the sentient, all-knowing system by my side, I might become the strongest. The strongest nameless character, how cool is that? But first... I should worry about surviving the calamity. === WARNING!!! We have a "pretty" MC here (Looking like girl because of a unique trait, just like Rimuru that has taken the form of Shizu). So, if you'd prefer cooler and handsome guy as your MC, this might not be to your liking. However, in term of character, he's kind of pragmatic (Expect a frustration toward his decision-making). Update? I release 2 chs/day with no fixed time yet. So make sure to add my book to your library! Hehe
