Shiryu's shield not really though you can bash someone on the head with it. those others guys, uhh I think they're filler so idw But the general consensus is almost all saints fight bare handed. few exceptions but no one else.
I never said it wasn't. I can't state my opinion on Dohko just yet since Ive yet to see his true form in the cloth so yeah.
Well on a side note I found Shaina's grieving over Cassios pretty heart breaking.
You know I doubt those silver saints are filler, later the story explains why, but still because the manga I am doubting a little.
About Shaina and Cassios, that is one of the facts of Saint Seiya touching moments, Shaina and Cassios is just a taste, later another couple probably your heart will break.
