This is the first title by Eclair. Spring has come once again for Kazuharu and he thoroughly enjoys his school life at Ouka Gakuen. However, he had once promised his osananajimi and older sister that he would ‘fall in love’. For many years now, he’d been called a good-for-nothing and chicken by girls around him. His freedom disappeared with the start of the new school year. He was surrounded by girls who tempt him at the school and at the worn-down dormitory Azuma-sou: his glutton osananajimi Kanae, miko senpai Matsuri, lewd imouto Chifuyu, self-proclaimed ‘good girl’ kouhai Miyu, and the stupid ghost Hiiragi who for some reason won’t go to heaven. It’s a daily life unlike any other. Let’s have an exceptional youth!
