Even if Raizel doesn't talk much, silent protagonists are SILENT, as in they NEVER talk. Example: Gordon Freeman.
Technicality. I agree, but in manga, I don't think you'll find more than ten (you might not find even five) that have truly "silent" protagonists - unless they're mute, in which case they don't count.
In the context, I think Rai qualifies. For most chapters he has no more than one or two lines - normally about going home and eating ramen.
________________ ABOUT ME 1. 10,000 chapters and counting. (...Otaku alert!) 2. I love Comedy/Romance/School Life (as you probably can tell!), especially when they're all together. 3. I welcome spiffy debate but I don't do quarreling (or forum trolling).
He talks like once every 5 chapters at most and usually just one word... kneel..... he has barely said more than 5 sentences by chapter 160.... any more silent than that is called being mute.... the main activity of the character is either looking like a supermodel, staring at a bowl of ramen, or looking like a supermodel while staring at a bowl of ramen.... oh and being epic..... words rarely can fit in the spaces as all his screentime is already accounted for.... or... pagetime I guess....
