A certain social phobe loves anime. After an incomplete cosplay, they became the character they were cosplaying.
Right after transmigrating, they heard a certain old-timer say, "Let me make you fall for me, Fushiguro Megumi!"
Shiina Chiyan stared at the heavens in speechless disbelief and thought, Should I start making my final arrangements?
In the end, unable to let go of his life and family, Shiina Chiyan came up with a story. As a devoted anime fan, Shiina Chiyan figured that if he was quick enough to kill off the characters, no one could kill him off first.
Shiina Chiyan "made up" a world. In that world, after the Six Eyes and Ten Shadows Technique were gone, Ryomen Sukuna had no opponents left. The jujutsu world at the time was so dull, with no one who could challenge him, that he sealed himself away.
Hundreds and thousands of years passed before he awoke. Perhaps he had grown fond of the quiet life and decided to retire, but things don't always go as planned.
During a war with the Outer Court, their world's Heavenly Dao was damaged. He and several others stormed the Outer Court's headquarters, and in the end, he died to restore the Heavenly Dao.
Everyone but him got a Happy End.
The above is the storyline Shiina Chiyan "made up."
PS: The old-timer in this story is morally aligned as chaotic good, because of his social phobia and certain other reasons.
PPS: The author's writing is at an elementary-school level, so some characters may not be well developed. Please bear with me.
Content warning: This old-timer never became a curse, but he's still very strong.
Theme: Mental health is just as important as physical health
