Summary
“The problem with any form of time travel is clearly outlined in the journal. If you get sent back, the timeline supposedly splits and your mind is left in a fractured state on both ends.”
Kanao feels her heart rate shoot up as her headache comes back full force. She gasps and turns around to face Shinobu. Her sister stares at her in shock at how abrupt she'd been, before she glares at her.
“Oh for fu-please, I'm trying to help. Plus, you shouldn't be moving so quickly.”
Or
Kanao and Kiriya end up destroying a very important artifact and wind up back in the Taisho Era. What can go wrong?

Summary
Tanjiro is new to the world of demons and slayers, but he thinks he will be okay. Giyuu is his role model, so surely he will understand everything soon enough. Unfortunately for Tanjiro, Giyuu is rather awkward when it comes to communicating. Worse still, Giyuu has dragged Tanjiro into his romantic life...or lack thereof. Tanjiro understands that Giyuu tries his best, but it is depressing to watch him stumble around and mess up every chance he gets.

Summary
Going back to the past means reliving everything that made you, well, you. It also means that Kaburamaru can mess with things in order to make sure Obanai doesn't miss his chance at making sure he can be with Mitsuri. He cannot go through that again. Not if he can help it.
