One of the most prominent among the Seven Heroes, Glenn is the son of the Emperor. He was appointed by the Emperor himself to handle the growing threat posed by Koinzell. During the era of the Fourteen Lances, they were close friends, but Glenn harbored deep resentment and envy towards Ascheriit due to his superior swordsmanship and calm demeanor. Glenn acknowledged the brutality of their betrayal and did not fear eventual retribution, believing that their punishment was becoming heroes, burdened with the welfare of the entire Empire as both nobles and symbols for the people.
In his first encounter with Koinzell, Glenn publicly spared Koinzell's life, but he was killed during their second encounter. Following Glenn's death, his father, the Emperor, fell into a deep depression and lost interest in ruling the empire. Consequently, Lebelont assumed de facto control over Szaalenden. However, Glenn was mysteriously resurrected with a younger body and the scar from where Koinzell had slashed him. He speaks of a mysterious plan to combat the weakness of people's hearts and aims to destroy Lebelont. Glenn has also disbanded his knight company and renounced his title as one of the Seven Heroes.
Among the Seven Deadly Sins, he represents Envy, as it was his envy of Ascheriit that led him to betray the Four.
