I see we have two sides of the battlefield and one secret agenda amidst them. Chaos is a ladder indeed, Sazanka Baelish, and she will have her lone Suzuran at the top.
see? my guess that Sazanka will gives her support to Tsubaki is proven right but I'm more curious to Sazanka's statement, that only one heroine will win in the end. what's the meaning of that? is she want Suzuran's harem to be destroyed so she come back to only choose Sazanka in the end?
