锁锁美同学@提不起劲

锁锁美（阿澄佳奈 配音）是一个标准的宅女，每天都窝在家里不肯出门的她懒得穿衣，懒得洗澡，甚至就连吃饭，也要靠自己那瞧不起的没用哥哥月读神臣（大冢芳忠 配音）帮忙才能得以完成。对于妹妹颐指气使的使唤，神臣非但没有觉得恼怒，甚至十分享受，因为从本质上来说，他是个有着“被奴役”体质的超级妹控。 　　最近，有件事情让锁锁美十分的不安，通过她亲自发明的“哥哥监视器”，她发现神臣的身边聚集了三个行为可疑的漂亮女孩子——外表萝莉实际上是个御姐的邪神剑（斋藤千和 配音），长相和个性都异常普通，但随时随地都昏昏欲睡的邪神镜（花泽香菜 配音）和外表看起来超成熟但实际上只有9岁的邪神玉（野中蓝 配音）。为什么她们的出现会让锁锁美感到不安呢？在锁锁美一直监视着的哥哥身上究竟隐藏着怎样的秘密？一切都尚在迷雾之中。The Japanese call them hikikomori-people who've become so withdrawn socially that they refuse to leave their homes for weeks and even months at a time. For Sasami Tsukuyomi, who's attempting to pass her first year of high school despite being a shut in, it's more than just a word. Fortunately though, she lives with her older brother Kamiomi, who just happens to be a teacher at the school Sasami is supposed to attend. Not to mention, her "Brother Surveillance Tool" which lets her view the outside world via her computer and will, theoretically, allow her to readjust to interfacing with people again. What it mainly does, however, is let her view her brother's interactions with the three very odd Yagami sisters, who inexplicably seem to have had their ages reversed and have various types of "interest" in Kamiomi. And then things start to get really weird... Magical powers? Everything turning into chocolate? Is life via the web warping Sasami's brain, or is it the universe that's going crazy?
