Demon Slayer: What Does It Take... To Move Forward?

Time is not linear. It is not a sequence of beginnings and endings. It is a collection of infinite possibilities. Ever changing, ever growing as variable of one timeline become constants in others. However, there are things that must be set in stone in order to continue on. There must always be a battle. There must always be losses to overcome. There must always be a price paid. Let's take a peek into the looking glass, shall we?
Cover is not mine if you want me to take down let me know.
