After Desir and his party defeat Boromir Napolitan to escape from the Shadow World, he finds himself sent back in time to the enrollment ceremony of his school 13 years ago.

Desir takes the test to enroll in Hebrion Academy, along with Romantica and Azest in Group D.

Desir is placed in the beta class despite his test result, and so does Romantica, even though she's a noble. Desir finds Pram, another new student from the beta class, and invites Romantica to join his party.

With Pram and Romantica, Desir aims to win the ranking tournament to get promoted to the alpha class. Desir starts training his team to draw out their full potential, based on what he remembers.

Desir and Pram attempt to get Pram's rapier back from the man he sold it to, and uncover hidden secrets in the process.

Desir, Romantica, and Pram shine in the ranking match qualifiers, gaining fame as Beta Class stars. Their success sparks tension at Hebrion Academy, where prestigious students plot to challenge them.

Desir and his team plan to survive long enough to place within the top nine, as they defend against the attacks from other parties. Then a monster has spawned, and Pram courageously stands up against it.

Desir and his team find themselves in the world of the Privius Clock Tower. They make it through the survival quest and come face to face with Blue Moon, Red Dragon, and Pine Tree parties.
