你还是不懂群马

神月纪原先是生活在千叶县，但家里要搬家到群马县，得知神月纪要搬家到群马生活居住，青梅竹马警告他，去了群马是不会活着回来的。于是神月纪在网上调查了群马的资料，净是发现了很多负面的信息。在进入群马县的高中后作为外来者，神月纪与过于热爱群马县的当地学生学习了很多群马本地的特色文化和本地的一些梗（虽然具体过程比较暴力比较颜艺），同时还卷入了群马县和千叶县的地域战争当中——

チバ県からグンマ県に引っ越すこととなった神月。引越し先への移動中にネットでグンマを調べてみると、そこに現れたのは恐るべき内容ばかり!　「地球上唯一残された秘境」「とりあえず一番いい装備で行け」等々。一体グンマとはどんな地なのか?　彼の身に何が降りかかろうとしているのか?

Nori Kamitsuki has recently moved to the Gunma prefecture from Chiba, following after Otoya Todoroki, a former friend who moved there in elementary school. While on the way there, he receives an ominous text message from Todoroki telling him to turn back and that once someone enters Gunma, they never return.

Ignoring the message, As Kamitsuki goes about his school life and makes new friends. These people make it their mission to prove any negative stereotypes surrounding Gunma wrong and show Kamitsuki all the ways Gunma is different from the rest of Japan—from its local foods and landmarks, the changes to its daily school life, and even the attitude of the people who live there. Gunma is widely regarded as the least popular prefecture in Japan, but they clearly don't know Gunma yet!
