Chapter 115: Achilles Heel

Achilles Heel ( 弱点, Jakuten) is the 115th chapter of the Kekkaishi Manga written and illustrated by Yellow Tanabe.

Summary
Yoshimori angrily attacks Kaguro, but Kaguro easily evades the attacks and invites him to talk about Gen Shishio. Kaguro points out that he moves faster than Yoshimori can form Kekkai. Kaguro destroys the section of roof Yoshimori is standing on, but Yoshimori keeps himself steady with a Kekkai. Kaguro explains that Kekkaijutsu is tied to the user's concentration and stamina, not strength, so Kekkai power will suffer if concentration is lowered. He provokes Yoshimori by talking about Gen, then demostrates by penetrating Yoshimori's Kekkai and slashing his clothing. Kaguro increases the power of his swords and charges again.

Shion observes the battle, convinced that Kaguro will win quickly.

Kaguro charges through Yoshimori's Kekkai, and the moment before he can strike, Yoshimori defends himself by creating a dark, flame-like aura around himself, which breaks Kaguro's sword.
