Defensive Wall

Defensive Wall (防壁, Bōheki) is the defensive ability of the Medium. It creates the barrier around itself, which is several tens of times harder than the Borg of a Magi. After absorbing Black Djinn and changing its form, the several barriers are created around the palm of its hand.

Trivia
