I think Haizaki being a first year will be a gag/joke in the series.

Think about it, tallest, edgy, looks the oldest, yet younger than both. Probably, there will be some scenes where he says senpai just for the laughs and hell of it. But I can see him ignoring it, or just adding "san" like Lucastv719 said.
