Dragon Clan: Recognize Yourself

Basic information: savior + female + S-level bloodline + dragon body protagonist + no cp + regret to save + a knife (more in the later stage) + sweetness (a little more in the early stage) + a Mary Sue OOC sincerely apologizes! ! ! (Although I don't know if what I wrote will collapse, but I'll kneel down first!) — "My name is tide Or tide·Ed·Rose·Nian Or Celia Edmund Rosethought, it doesn't matter. I was quite miserable in this world. I lived to be 4 years old without a father and mother, and then I was picked up by an old guy, and then I became an S-class inexplicably. Then the system told me to be the savior, and I said yes. After all, I didn't want to see them end so tragically one by one, especially that weak child, that other "I" who was just like me. I'm thinking that in the future I must grow into a person who can truly save everyone with my own abilities. I also hope that I won't be as useless as my former self in the future. Although it seems that my life experience is not so blank, it has just been forgotten, just erased, but there are still people who remember it. Although I don't know who remembers it, that person must be very important." —About tide's own self-report — "The cherry blossoms are falling, silently mourning, no sighing, no sorrow, no worries, no difficulties" "I will return like the wind and leave like the wind" "Sister is innocent of accusation, double ring is eternal" (The author has something to say: Believe me, it is really sweet, except that the protagonist dies again and again^_^)
