This is the fandisk for Imosen adding the 366th imouto Artemisia. One month after the harem end, a coalition was formed with Kikka as the leader of the imouto council. Then the 366th imouto appeared as their teacher. She also started up a new party (Tachiagare Imoutou) advocating an imouto harem and happiness for all. With the coalition and the new party facing off in a dissolution election, things are lively as always at Academy Tachibana.
