A Journey Through Worlds: Starting with Demon Slayer

OOC warning: many liberties taken with the source, and the ending is rushed, so I don't recommend reading it.

What do you do when all your older brothers are villains? This is an unconventional transmigration story.

Who wouldn't love a handsome villainous older brother? Who wouldn't love one whose heart and eyes are full of you, his little sister?

Since the story is under contract, I can't change a lot of things. Also, because of my writing, the plot isn't evenly distributed: Natsuna gets less focus than Chiyuki. But I'm truly their loving mom, and Natsuna will get more scenes later. She's not a supporting female character. It might not be obvious from the story, but her past life left her with self-destructive tendencies, and she won't actively form bonds with others.

Chiyuki isn't especially fond of talking to people either. At first, she wanted to merge with her sister and return everything that belonged to her, so she didn't dare spend much time with her. She was going to disappear sooner or later.

Her sister has irreplaceable strengths, too. She's her little sister's anchor, a creator, and a whiz with computers.

I've given it some thought, and decided to make the story less tragic. I'm changing the outline.

One more thing: the intelligent AI created by the older sister will be the protagonist of my next book. Well, I do have a bit of a habit of putting my protagonists through physical suffering, so the focus shifted toward poor Chiyuki.

They're both my precious girls, and I'll do my best to give them a happy ending.
