Gas Masquerade of Miasma

"You all will not be heroes. You'll be Living Sacrifices, will you not?" Atsuto thought that by going to another world his unremarkable life would change and he would be granted all sorts of powers. However, in that other world he found nothing but despair. Atsuto is an ordinary and unpopular high school student with no remarkable talents or romantic success. One day, his school is enveloped in light, and he is suddenly transported to another world called Tilunog. Some students who believe they can become heroes with cheat skills are excited about the transfer to the otherworld. However, a beautiful woman from Tilunog named Philia cruelly informs them that they were summoned to be sacrificed, and that they are destined to be killed.

A poisonous atmosphere known as madness settled over Japan, causing mass devastation. Humans, wearing gas masks, hunt and kill monsters transformed by this gas.
