Spoiler: Riful's analysis and Yagi's indirect explanation of Galatea's technique
show"Her specialty is the reading of youma energies down to their most miniscule details. Thus she can control her opponent's movement by aligning her own youma energy with this. But even if I say control, it's not quite as awesome as it sounds. It only works by attacking the enemy in unguarded moments, exploiting weak points in his consciousness and tampering with it, using just a little of her own youma energy. That means even if she can manipulate the enemy's movement, stopping the attack itself is nearly impossible. Even more so if he is more powerful. That's why it's necessary to confuse him as a first step. While the enemy is negligent and unfocused, she shows him many little tricks and thus creates doubt. This is where my part comes in. An attack executed with doubts about whether it will hit or not is naturally far from ones full potential. That's why when a stronger opponent launches an attack with full force and no doubts whatsoever, even if it looks the same, there is absolutely nothing she can do."
