Main Visual Highlights Music Festival Arc
The newly released key visual for the fourth season showcases Iruma Suzuki alongside the entire Abnormal Class, dressed in dazzling costumes under stage lights, hinting strongly at the focus on the “Music Festival Arc.” A significant highlight of this visual is the prominent inclusion of Purson Soi, the enigmatic 13th member of the Misfit Class, whose character is expected to play a central role in the upcoming storyline.
Teaser Trailer Delivers Musical Intrigue
A captivating teaser promotional video has also been released, featuring a memorable trumpet motif that further underscores the importance of the Music Festival. The trailer hints at the challenges the Abnormal Class will face as they strive for unity, particularly in bringing together all thirteen members, including the elusive Soi Purson, for their stage performance. This initial glimpse has ignited excitement among fans, eager to see how the class will overcome obstacles to achieve victory.
Expected Plot: The Purson Soi and Music Festival Arcs
Following the events of the third season, which covered the Harvest Festival arc, the fourth season is anticipated to adapt the “Purson Soi Arc” and subsequently delve into the “Music Festival Arc” from the original manga. The Purson Soi Arc will explore the Abnormal Class’s efforts to encourage their incredibly shy classmate, Soi Purson, to participate and integrate with the group for the grand musical event. The Music Festival itself will present the students of Babyls Demon School with a major challenge, testing their teamwork and individual talents through a series of dance and music performances. The stakes are high, as Professor Kalego Naberius has indicated that the Abnormal Class can maintain their prestigious Royal One rank if they successfully achieve Demon Rank Four.
