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 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.

Desir and his team have finally faced the Blue Moon party for the chance to become single rankers. Azest puts a stop to Desir's plan of pitting the alpha parties on each other, but Desir has another plan. And he asks Azest if she is having fun.

After successfully defeating the challenge of becoming single rankers, Desir, Romantica, and Pram make the most of time to unwind before they join the alpha class.

Desir, knowing that Tear of Regernel will be stolen by the Outers, takes the initiative to stop them. As expected, Kraiken and the others show up at the Magical Tower. Can Desir protect the magical gem?

Desir and Kraiken are now fighting one-on-one over the magic gem. Can Desir protect Tear of Regernel? And what does Desir hope to achieve by protecting it?
