Mairimashita! Iruma-kun S02E03 - A Lovely Demoness

Someone had done something to change Ameri`s personality! She`s usually confident and stern, but now, she`s now meek and dainty and the student council can`t hide the fact that they`re not sure how to handle the situation. While all this confusion is going on, Ronove Romiere, the president of the Disciplinary Battler comes to try to steal Ameri`s position. He proposes a dissolution election against the student council. Who is behind the changes in Ameri? What will be the result of the election?
