@T51 This manga chapter ends at the same place as the 21st novel chapter. You can find where to read it on the NovelUpdates entry linked on the Information tab on the title page
For anyone who is curious, "Futsal" is basically a shorter and smaller indoors football(The name literally means Football in a Salon), it's pretty common in South America for students to play it during PE classes(Kinda like how basketball is to americans)
