[Demon Slayer] Whose Big Sister Am I?

She was a passerby, a storm of snow that should never have appeared, gone in the blink of an eye.

Ruoxue transmigrated, though her experience was a little different from the usual.

No matter how many times she transmigrated, she kept circling around the same country. From the Heian period to the Taisho period, every time she opened her eyes, she saw a different set of siblings.

Ruoxue: Fine, whatever.

After transmigrating, she took things as they came and did whatever she wanted. Then one day, she realized that all her reincarnations had something to do with a certain damn guy, and she finally fought back.

Ruoxue: So it was you all along!

In the end, her long life and tangled fate reached their conclusion. After countless awakenings, the girl finally found peace.

Ruoxue: Thank goodness, I can finally go to hell.

Ruoxue: ...

Ruoxue: Wait, don't come any closer! Aaaaaah! I may be your daughter/big sister/little sister, but that was all in a past life!

Her family was pretty easy to talk to, but unfortunately, the ones waiting for her in hell included not only her family, but also all her ex-boyfriends...

Ruoxue: Please leave me alone. Seriously.

1. I'm writing this for fun, so please don't nitpick the details...

2. The heroine may become the older or younger sister of main characters, background characters, or even fictional characters, including biological, half, adoptive, and fellow-disciple siblings, among others. She may steal some of their plotlines, so if that bothers you, please leave. Let's part on good terms.

3. There will be romance, and lots of ex-boyfriends, probably. There will also be somewhat intense and complicated feelings between biological older and younger siblings, but nothing actually incestuous (the site doesn't allow it, just ask me).

4. Some couples will be broken up, except for a few genuine couples and the ones I think are canon (Komaeda and Yukizome, Yushiro and Tamayo, Obanai and Mitsuri).

5. The heroine will go to hell, and she will unknowingly eat people (with this many tags, can this story really be paid? Okay, I'm joking).

6. As for saving people, I'll try to save everyone in the Demon Slayer Corps, but I'm not sure about the background characters. The third-ranked Upper Moon definitely won't become a demon. The rest of the Upper Moons and important demon characters are undecided.

7. The heroine's only cheat abilities are combat skills that are better than average but not the best, and occasional memories of the original plot. She will fail, be helpless, and compromise (I like reading that kind of thing).

8. Each lifetime's plot varies in length. Some will be very short.

9. In short, if you're not enjoying the story, you can leave. Don't insult me or the heroine. I'll delete unfriendly comments and comments that deliberately derail the discussion. That's all. (Why do I keep adding more disclaimers?)
