#スニーカー文庫35周年 配信イベントご覧いただきありがとうございました！ 発表にもありました通り、 #クラにか 【アニメ化企画進行中】です🎊🎊 制作はまさにこれから！ですが、放送されるその日まで、原作小説＆コミックスの変わらぬ応援よろしくお願いいたします‼️‼️

Without mentioning the studio or release window, the announcement brought with it a first image highlighting the character Umi Asanagi (check it out below). 

Abbreviated as 2nd Heroine, the young adult novel tells the story of Maki Maehara, an ordinary boy with hobbies typical of his age, including watching shark movies or playing video games while trying snacks, pizza and soft drinks. In a new school year, her class welcomes two new students: Yuu Amami, considered from then on to be the most beautiful teenager in school, and her friend Umi Asanagi, seen as the second most attractive girl in school. Believing they are in different worlds, Maehara is surprised when Umi approaches him and asks: "I want to be your friend, can I watch movies at your house?" Since then, an expressionless boy and the second most popular teenager in high school have become close, hiding their friendship from everyone. 

 The novel is written by Kaku Takata with illustrations by Tom Osabe, with 4 books published in addition to 2 volumes of the manga drawn by Rin Ono. In total 200,000 copies were sold by May of this year.
