Serie: Hinomaru Sumo
Characters: Reina Gojo, Hinomaru Ushio
Détails: Reina (images 1-2) X Hinomaru. She's naked. Be careful, Hinomaru (157cm) is smaller than Reina (167cm).
You can be inspired by the fourth image for the position.
It's not obliged to draw Hinomaru (image 3) in full but use the same body / scar so that we know that it's him.
