There isn't a single person in Sakuradamon High who hasn't heard the legends about Seiji The Mad Dog Sawamura's demonically powerful right hand. His reputation makes it fairly difficult for him to approach girls, and after being rejected 20 times straight, he half-jokingly vows to finish high school with his right hand for a girlfriend. Much to his surprise, after waking up the next morning, Seiji discovers that his demon right hand has mysteriously turned into a miniature girl, Midori Kasugano, who reveals that she has had a crush on Seiji for the past three years. Because their situation is not ideal for either of them, Seiji attempts to return Midori to normal. But after causing a big misunderstanding at the Kasugano household, the pair decide to keep their predicament between them until a solution is found. Thus begins an odd relationship, and what could be the only chance for Midori to finally be with the one she loves.

At Kaimei High School there is a special club dedicated to helping others known as the SKET Brigade. The brains of the group is Kazuyoshi Switch Usui, a tech-savvy otaku who speaks through speech synthesis software, while the brawn is provided by Hime Himeko Onizuka, the hockey stick-wielding girl once known as Onihime. And last but not least, their leader is Yuusuke Bossun Fujisaki, whose latent ability is evoked by his goggles, allowing him to summon the awesome power of extraordinary concentration. However, most of the school only know them as the club that handles odd jobs. Many of their days are spent in the clubroom slacking off, but when there is something to be done, they give their all to help others—usually in sincere, but unintentionally hilarious, ways. The SKET Brigade do all they can to provide support, kindness, encouragement, and troubleshooting to any students crazy enough to ask for their services.

With the second Winter Comiket just around the corner, Blessing Software has been vigorously producing its new game, How to Raise a Boring Girlfriend.

Saenai Heroine no Sodatekata Fine draws the series to a close as Tomoya selects his final route, both within his personal life and Blessing Software.

Imagine living life as the vice president of the student council, passing the days eating snacks, playing games, and bonding with a harem of beautiful girls. This is exactly the kind of life that high school student Ken Sugisaki leads, or so he thinks! Usually, the officers of Hekiyou Academy's student council are elected by popular vote, but an additional position is granted to the student who scores the highest on the exams. Ken, who historically has had below average grades, worked hard to improve them to be accepted into the student council, with the ultimate goal of surrounding himself with girls who fawn over him. Unfortunately for the vice president, things do not go quite as planned. Not only do the ladies of the council continually rebuff his advances, they also prefer to focus on more important and boring activities, such as organizing school events and managing the other clubs. But a few minor hurdles like these won't stop Ken from chasing after his dreams, even if they seem a bit ridiculous.
