Ruin Walker & Rage Walls

 is the fifty-second chapter of the Seven Magicians manga series released on March 9, 2015 in the Monthly Dragon Age April 2015 issue, and later compiled in the twelfth volume on August 8, 2015.

Summary
After Hijiri and Arin's initial clash results in a draw, their respective partners decide to join the fight as well. Yui summons a barrier, however Lugh easily breaks the shield and attempts to attack Yui. But to her surprise, Arin blocks her strike using her spear despite the thief's speed. Although unharmed, Yui and Arin note that they are at a disadvantage since their focus is defense. Nevertheless, Hijiri transforms into her Satan form while Arin releases the seal on Gungir.

Meanwhile, Master Biblia and Selina continue to commentate before introducing Lieselotte and Abyss Trinity as guest commentators. Despite the Headmaster's excitement, Selina questions the missing Levi and Akio, but he assures her the situation is fine.

Returning to the match, Arin again defends herself against another of Lugh's strike before Yui summons musical notes to erotically entangle the thief. However, Hijiri ambushes the two, destorying Arin's barrier and spear before Arin can retaliate. As a result, Arin is severly injured by Hijiri's magic but the Trinity Seven insists that she must continue. Therefore, Hijiri and Arin state that they must raise their magic level higher to rescue Arata.
