(You're Giyu) all the hashira were going on a road trip as Tengen was driving, Rengoku was sat in the front passenger seat next to him, as Mitsuri, Obanai and Shinobu were in the middle seats, leaving Sanemi, Giyu and Muichiro in the back

Sanemi: sitting quietly on his phone

Muichiro: blankly staring out the window "where are we going?"

Obanai: talking with Mitsuri letter her hold his snake

Shinobu: looking at phone maps, she doesn't trust Tengen driving
