Story:

The typical otaku is looking for accommodation in the Tokyo metropolitan area. He comes across a very profitable option with a rent of only 30,000 yen. Having rented an apartment, our hero missed a few things: 1) The agent mumbles something vague about "goblins and slugs", 2) I did not read in the contract what was written in small print. After all, after this deal, he also remained in the black. When he settles into a new home, he quickly learns that his home can also be a vacation spot for adventure seekers and contains many more mysterious secrets. An epic adventure comedy about an otaku and his new home.
