The Heroes begin their final mission, but they weren’t the only ones fighting that day. While they battled the enemy, the Sentinels were holding the line.
Karin rages against the gods who cursed Yuuna, but they don’t answer when she issues a challenge from beyond the barrier. Instead, she finds the Sentinels and an old rival.
Sonoko’s family possessed The Hero Records for generations. When she entrusts it to the Hero Club, they learn about the first heroes who defended humanity against the Vertex.
The Sentinels do not have the powers of a hero, but they have each other. When the Vertex unexpectedly attack, Mebuki and her team face a battle unlike anything before.
The Sentinels have a dangerous task. Although Mebuki’s leadership has prevented fatalities, not everyone stays. Those who leave are replaced as if they were nothing but tools.
The members of the Hero Club look forward to resuming their normal lives. And that means fun activities like band practice, karaoke, airsoft matches and camping trips!
