Outcome

And that's when Rui noticed something odd.

Freund was continuously breathing with his mouth open. Not just a little open, he looked like he was trying to pump out air as much as possible. If he was exhausted, Rui would not have minded, but he shouldn't have been that exhausted that quickly. Furthermore, there weren't any other signs of exhaustion that accompanied heavy breathing.

Rui's eyes widened as he realized what was happening.

('He's exhaling poison!') He mused with absolute incredulity.

Rui couldn't even begin to fathom the kind of body conditioning Freund Gamor had put himself through to obtain that kind of technique. It also explained why he removed his mouth mask. Everything fit.

Furthermore, this technique was especially effective against Ian. Ian was abusing breathing techniques the entire fight, taking in an impossible amount of air every second.

A technique that poisoned the very air was a technique that was extremely well-suited to taking Ian down!
