Blue Exorcist 19 Kato Kazue (2018)

Rin and his exorcist classmates are caught in a secret war against the forces of darkness. Raised by Father Fujimoto, a famous exorcist, Rin Okumura never knew his real father. One day, a fateful argument with Father Fujimoto forces Rin to face a terrible truth: the blood of the demon lord Satan runs in Rins veins. Rin swears to defeat Satan, but doing so means entering the mysterious True Cross Academy and becoming an exorcist himself. Mephisto Pheles has freed his brother Amaimon from imprisonment and set him loose on True Cross Academy to serve his own agenda. While the Exwires deal with Amaimons surprise reappearance, Lewin Light, also known as Lightning, continues to investigate the mysterious Section 13 and its connection to the Blue Night event, which seems to be the source of all the current troubles. Together, they delve deep beneath True Cross Academy, shedding light on long-lost chambers shrouded in darkness and the terrible secrets buried there for a reason.
