A collaboration between Episode and That Time I Got Reincarnated As A Slime brings the Rimuru Battle t-shirt in a black colorway. On the front is a graphic of Rimuru herself with a determined look on her face, her hand resting gently on the hilt of her blade as if ready to draw at any moment. On the back side is a larger graphic of Rimuru with her bat wings extended and her katana shooting bright flames that draw the eye. This graphic tee is constructed of a midweight cotton, coming complete with a tagless neckline for all day wear.
