Transparent World: A sensory state reached by those who have mastered martial arts, allowing them to see through the opponent's body and movements, drastically improving prediction and evasion. Mark: A symptom that often manifests in Breathing users. During intense combat, a mark related to their Breathing style appears on a part of the body, similar to a demon's crest. Basic Effects: Physical abilities are enhanced to the point of overwhelming Upper Rank demons, who are normally no match for humans even with Breathing techniques.
