From the Reincarnated As A Slime 'I Became a King' Ichibankuji lottery, this figure shows Guy casually using Rimuru as a seat.
Originally, this was only available as a prize in a Japanese 'Ichibankuji' lottery. However, we can save you a trip to Japan thanks to Banpresto providing European distribution for the prize figures! Unfortunately, this does mean that we don't have any of the smaller prizes from this Ichiban Kuji set available.
Warning: this is not a toy. These are collectable items for adults or those over 15 year of age.
