The story is set in a world where humans with magical powers are on the verge of extinction. The highest realm of force has changed from using swords to using magic, and then to using guns. The protagonist Kusanagi Shou, who is studying at the "Anti-Magic Academy", a professional institution for training "heretic inquisitors" to eliminate the remaining magical threats, is an alternative who can't use guns at all and can only rely on a sword to fight the enemy. The 35th Test Team he led is also known as the "Trash Team", which, as the name suggests, is a team made up of a group of inferior students. One day, Feng Yinghua, a super elite gun master with the qualification of "Witch Hunter", unexpectedly joined the team. As he led the team to set off to carry out the task of recovering the magical legacy, a school action fantasy masterpiece began.
