Synopsis
Shougo must marry a classmate before graduation, but one girl might be his secret half-sister.
Shougo Mikadono's father has just passed away, and now he must become the head of Mikadono Group, his father's company. After completing the training to take over, there is just one other stipulation he must adhere to: he will need to find a girl he loves at his new school and marry her by the time he graduates high school. Shougo transfers to Miryuin Private Academy, and it seems like he has many girls to choose from, such as Konoe Suruma, the class representative as well as his first new friend; Miyabi Kannagi, a standoffish but kind girl; Rinka Kunitachi, the student council vice president; Mei Sagara, who runs a cafe and dresses like a witch; and Mana Tendou, the student council president. However, there is a complication: one of them is his long-lost half sister, and he has no idea which one, so how can he become romantically involved with any of them?

- 8 “There’s nothing to praise here: the whole show is just a sleazy harem setup whose core mystery gets laughed off with the gag title “Will I Bang My Sister?” Every girl is reduced to a horny...”
- 8 “The sister guessing game delivers a trashy kind of fun, but that fun comes from watching the protagonist panic over possibly romancing his own sibling. Beyond that gimmick, the show feels hollow...”
- 8 “The serious setting and central mystery of the hidden sister give the show a story-driven hook that sets it apart from lighter harem fare. Still, it leans too little on the comedy and fan-service...”
