When They From the Age-Reversed World Came to the Original Story

After a grueling day, Sun Pillar Tanjiro fell into a black hole in full view of everyone during a postwar recovery period. Wind Pillar Yuichiro tried to grab him and got dragged in too, tumbling in face-first. The two of them rolled through the black hole and landed in the original story's world, smashing through the Butterfly Mansion's roof amid Original Zenitsu's shrill screaming. Facing the people of the original world, Sun Pillar Tanjiro said: ...Hi? The character designs were inspired by some creators' short comics, with changes. Their finalized identities are listed in the main character section. The alternate Tanjiro's master has been changed to the former Flame Pillar. He's my OC, the heroine of my other crossover story next door, Lisan San. Everyone in the alternate world survives. Any plot holes are San San's problem. The ships in this story include Tanjiro x Kanao, Zenitsu x Aoi, Giyu x Shinobu, Sabito x Makomo, and Obanai x Mitsuri. So if you like BL ships or really can't stand het ships, this probably isn't for you, since I'll be sneaking in my own het-ship preferences as the story goes. To avoid an unpleasant reading experience, please remove it from your favorites and leave. Chapter one was published on January 18, 2020, before Demon Slayer had ended. The Blue Spider Lily has a headcanon version in this story! My writing is awful, so read at your own discretion. Due to moderation, I'm leaving minor typos that don't affect the reading experience uncorrected, qwq (please be gentle). Theme: Life is but a dream, yet heroes still burn with passion.
