What are you arguing about? The statement I quoted said that “samurai” is plural. Nothing that you said has contradicted that. In fact, you’re only agreeing with it with this last statement. Doesn’t matter that it didn’t mention if it can be used as singular as it’s not relevant.
I said Japanese though, not English. “samurai” is both singular and plural in both languages
