The Kingdom's Darkness!

The final match in Group B: Brazil's The Kingdom vs France's Rose Griffon, has ended with The Kingdom winning overwhelmingly. This amazing team is also Inazuma Japan's opponent in the semi-finals. Everyone, especially Endou, are excited to play against them. But their captain, Mac Roniejo, comes to Endou with a shocking proposal. He wants Inazuma Japan to lose in the semi-finals. Why would someone as strong as Roniejo want to set up a
fixed game? Did something happen within The Kingdom? And does this has something to do with their coach, Garshield?
