I finally got the chance to see Demon Slayer about a month, a month and a half ago. On episode 10 Nezuko had a battle with a Kemari. It very quickly started to resemble Captain Tsubasa. There was even a scene where she was charging up a kick and it looked just like when Kojiro shoots his Tiger Shot. Drawn using a maru pen. At first I was going to have Kojiro in his Soccer uniform, but I felt his training outfit would look more flashy. Specially if it was open and flapping with the movement.
Hasta la proxima,
