Synopsis

The Mikadono Group (帝野グループ, Mikadono Gurūpu) is a worldwide business company based in Japan and led by Kumagoro Mikadono. He names his son Shogo heir to his position in the company. However, after Kumagoro dies, his widow Kanoko becomes the new acting chairman as Shogo transfers to his father's alma mater Miryuin Private Academy. According to his father's will, Shogo will take over the company after he graduates provided that he finds a life partner before then. Fortunately, there is a large female population at Miryuin Academy to choose from. Life at the academy will not be all smooth sailing, however. He is immediately popular because of his name and position as heir to Kumagoro's company and has caught the eye of several female students. To complicate matters further, although he was raised as an only child, Shogo apparently has a younger half-sister who was raised separately who also goes to the same school and intends to get closer to him without revealing her true identity. How will he act knowing that any girl he chooses to be his life partner may also be his sister?

This leads to Shogo trying to find his sister. He has a scar on his forehead from an accident when he was kid that caused him to lose some of his memories. Eventually Shogo chooses Konoe to be his lover but she is revealed to be Kumagoro's illegitimate daughter.

She revealed later that she was Shogo's childhood friend and feels responsible for the accident which landed him in hospital. She has the same phone as the mysterious shadowy figure shown once calling Shogo. It is later revealed that she was also the one who sent him the cake, photo, and action figure on his birthday. She initially called him using the voice of Perin a character from "Transforming Warrior Granberion". She is in love with Shogo. This is underscored when she tells Shogo, "When we were kids, I wanted to be your sister. I figured we could be together forever that way." The phone she used was a prototype developed by her father with a rare voice changer feature. Eventually she becomes Shogo's lover but also reveals that she is Kumagoro's illegitimate daughter.

After that, she overheard his conversation with Konoe and after seeing them almost kiss, demands that he kiss her. She reasons that after Shogo calls Konoe "just a classmate," it should be fine for him to kiss her as well. When she tells Shogo of their previous relationship together, she also confesses (with Konoe present) that she fell in love with Shogo as a child and along with Konoe was elated upon learning of his transfer to their school. She is competitive with Konoe about wanting to marry Shogo, to the point where they will argue about it in front of him. As the story progresses, she often interrupts romantic moments between Shogo and Konoe. At the end of the anime and in volume 4 of the novel, she is believed to be his sister.

Reception

The English language adaptation of the anime, released in North America received mixed reviews. Allen Moody from THEM anime reviews, gave the series one star out of five. He called the plot a simple mystery that isn't challenging, and pointed out multiple anime clichés such as the loss of important childhood memories. Andy Hanley from UK Anime Network gave the first four episodes of the series a 2/10 rating citing many plot holes, and "wafer thin" characters. He goes on to say good things though about the character designs and animation as the only redeeming qualities. Chris Beveridge from the Fandom Post gave the series a more positive review saying that there are likeable main characters, with each earning "their time in the sun". Chris had previously given the first two episodes a C rating calling the animation "very cheap and stiff" in a lot of scenes, and Shogo's character "bland". Active Anime also gave the series a good review, describing it as good for people who love romantic comedies with fan service. The review also points out that they left the anime ending on a "pretty good" spot in the story as the light novel series hadn't finished in Japan. Jeff Chuang from Japanator called the series "above average" for its harem genre, but also said it isn't an anime for those who cannot handle the intense sex jokes.
