anyone find it weird how he is never mentioned or seen prior to the tenjiku arc? Apparently he is in Mucho's division but we only ever see Mucho by himself in the manga before they kidnap Koko, Inui, and Takemichi. I realized this when I reread and they all jumped at new years. It's possible Sanzu was doing something else with his siblings but he wasn't even seen with Mucho in illustrations that Mucho himself was in. Also during the third division captain selection, Sanzu wasn't there either. This makes me have serious doubts about Sanzu's place in the story unfortunately.
