"I Was Reincarnated, But It Was Already Over ~From Big Sister's Perspective~"

This is a sequel to "I Reincarnated and It Was Already Over," told from the older sister's perspective. It's a story that could be seen as the rampage of a sister complex-afflicted older sister. It's a serious work that cannot be taken seriously. While I believe this can be read as a standalone piece, I would be grateful if you would read the previous work first.
