Theories about Mahiru being S4 in Year, One, really no other main characters being competitors, second, "one youngster" rule.

Maybe as you say suddenly a new Beauty character pops out and beats down Mahiru. Personally, I would wish that Koharu gets a chance in Year 3 instead.

As for Haruka, her being is also contradictory with the conditions mentioned. She cannot beat down Yuzu, and in Year 3 she would not be able to join as Ako is there (type theory).
