Previous, Ahead, Past, Former
Slide some dirt on your legs so you can feel like you're from a previous time. Everything from the past is in the dirt. Dead people, dinosaur bones, your mom's secrets in a box from her past life. All these things come back to you as you slide the dirt all over your legs.
Imagine the feeling of dirt on your legs. Now think back to the previous day. The previous year. The previous century.

As you sit there, pretending you're in a previous time you see a centaur (せん)! That's right! Centaurs are from wayyyy in the past.
Centaurs were definitely real in the past. Don't let anyone tell you otherwise. They're just afraid of the truth.
