Silent Witch: Chinmoku no Majo no Kakushigoto

Monica Everett is one of the Seven Sages and the only magician capable of casting spells without speaking. She even defeated a legendary black dragon alone. The truth behind that incredible achievement is far less majestic: Monica developed silent magic because she is painfully shy and wanted to avoid talking to people.

Her secluded life ends when she receives a secret mission to protect Prince Felix at Serendia Academy. To guard him without revealing her identity, Monica must enroll as an ordinary student and survive classrooms, conversations, social events, and assassination attempts. Facing enemies is familiar; introducing herself to a classmate may be the harder battle.
