Along the way he'll meet the river's other residents, including a hot-blooded kappa, a Sister in drag, and a literal rock star.

的确，在被称为“绝望先生”的超消极老师糸色望的带领下，2年へ班全体32人都是有一点儿不正常的人。口头禅是“绝望了！对xx的世界觉悟了”的望，与学生们一起生活的爆笑校园喜剧就这样再次开始了。

A teacher takes all aspects of life, word and culture in the most negative light possible.

Following Madoka's rewriting of the universe, sacrificing herself and her happy normal days to save all magical girls from the cruel fate that awaited them by wiping witches out of existence, the despair still manifest into creatures known as nightmares. Magical girl Homura Akemi continues to fight alone in the hope that she will be able to see Madoka smile again.

Even when you're fortunate enough to live in a place as beautiful as the country village of Asahigaoka, you should never turn down the chance to explore someplace else. So, when Suguru wins a free trip to Okinawa just as the summer vacation is coming to an end, the town's entire school… all 5 students and 1 teacher, plus the local candy shop owner… can hardly wait for their 3-day trip to begin! Between kayaking, swimming and meeting new people, there's always something fun happening, but the best part of all is that big city girl Hotaru and her new small-town friends all get to explore the wonders of Japan's famous vacation destination together.

The carefree journeys of the four girls continue! As their fleeting yet eventful summer becomes a distant memory, the arrival of fall signals a new school year with limitless opportunities. Even as the four girls return to their peaceful routine, the appearance of new faces enlivens the anything but exciting rural life of Asahigaoka.
