Tsuda also meets the other student council members while getting scolded, and in the end, he gets late for class. As an apology for ruining his morning, Shino lets him join the student council for various of reasons and he accepts it, or rather, he's forced to accept. Thus begins his days as Tsuda soon realizes that he's the only normal student in Ousai Academy...

Yuuki Akamatsu lives a normal high school life... that is until his cousin, Ayaka Nikaidou, convinces him to join the Journalism Club as a life consultant! His new job is to manage the advice column for the school's weekly newspaper to help him become more social. Soon, Yuuki is joined by three girls: the smart and shy Rino Endou, the athletic and outgoing Ikumi Suzuki, and the cultured and sweet Fumi Kujou. Together, they solve the personal problems of those who anonymously ask for advice. Although each of the new life consultants has their own unique perspective, they are able to reach solutions together by holding debates and social experiments throughout the week. However, as time goes on, the four slowly come to realize that they have not only been guiding other students through their troubles, but also working through problems of their own as well.

Oda Akira is the kind of guy who people forget is even there.

Between his suspiciously high starting stats and too many details that don't fit, Akira is sure something is wrong. But digging into royal secrets is a dangerous game, and when Akira uncovers an evil scheme, he also makes a powerful enemy—the very king who brought him to this world! With the help of the elven spirit medium Amelia, can he find the power to set things right, and get his revenge? (Source: Seven Seas Entertainment)
