Mitsumune's grades are excellent but he doesn't boast about it, and he easily trusts even-tempered people.

30 young men and women who came together on a shady bus tour. The tour's destination: an illusive, possibly nonexistent village called Nanakimura. In Nanakimura, one can lead a utopian existence, free of the world's obstacles … or so it was rumored, like an urban legend. 
 
"In despair over the real world ... wanting to escape the tedious daily life … wanting to restart your life from scratch …" 
 
The bus headed deep into the mountains, carrying 30 people each harboring their own expectations and wounds in their hearts… 
 
And so, the place these 30 arrived at, was an uninhabited village with the lingering faint scents of life, even though it was falling apart. 
 
What is the truth of Nanakimura facing the 30? You can't miss even one episode!
