Sumo fans should be given more information about Homarenishiki. If conclusions are being drawn, it's because no one is saying anything.
He returned home to Canada last month and is thinking about quitting sumo because he was treated so poorly at Nishikido. Poorly, meaning far worse than the typical bullying of a newcomer. There could be legal action involved.
I have nothing 'legally' prohibiting me from saying this.
How do I know? I'm in Victoria and friend of the family said as much.
