Set Your Heart Ablaze: Achieving Peak Performance through Total Breathing Concentration
Keywords:
Manga/TV, Biology, Aerobic respiration, Biomechanics, Sherpas, Kimetsu No Yaiba, Total Breathing ConcentrationAbstract
In the manga/series Demon Slayer, a group of humans use a technique known as Total Breathing Concentration. The Demon Slayers use this technique to grant them almost superhuman feats, as demons can wield supernatural powers. This paper will dive into the biological basis of energy production and use of this technique, as well as investigate its feasibility beyond the realm of fiction.
