The grown tree was more than 30 cm thick. Even if Kirei wanted to use his outrageous strength, it was impossible for him to break or uproot the tree. At last, he was completely immobile.

And even then, Irisviel was the one who steadily lost her advantage underneath Kirei’s strength. In theory, Kirei’s hands should have been overpowered by the pressure generated by the silver thread. Yet, his muscles were trained to the point where they appeared steel-like, and they were powerful beyond all belief. Her silvery thread almost broke, as they struggled underneath the saturated state of near-collapse. In order to keep it tight and to prevent the metal from breaking, she must constantly use her mana to maintain it.

“…Maiya-san….hurry!”

It could be said that the two women still mistakenly underestimated the terror that is the Executor of the Church.

With no knowledge of Chinese kungfu, Irisviel thought that it was only necessary to bind Kirei’s hands to render him helpless. It was not her fault that she only thought like that. However, for someone who managed to reach the level of training such as Kirei, the entire body is a weapon. For example, if he only planted both feet on the ground…

“BOOM,” the deafening sound rendered Irisviel speechless.

The tree trunk shook erratically. As if struck by a full-powered fist. That means the sound she was hearing – only someone using his full strength to strike at the center of the tree could make that sort of sound.

The clear strike sounded again. This time, she started to doubt her ears. She heard a chilling sound of breakage.

She could not see the situation, but Irisviel understood through the touch of her silver thread. The tree trunk that bound Kirei had large cracks in it. The cracks were next to the part where the silver thread wrapped around – the spot directly below Kirei’s hands.

Kirei, with the back of his hands pressing against the bark, was striking at the tree trunk with all of his strength.

Irisviel could not have known – but the strength from a martial arts master is not merely produced from the wrist. From the strength of the feet on the ground, the turning of the back, and the twisting of shoulders, it was possible to instantaneously release a burst of power in the fists. To an expert in this phenomenon, the strength of the arm was insignificant in comparison to the power of the whole body. If it was necessary, one can press the fist next to the target and strike simply by virtue of the “force” coming from outside of the arm – this is known as the hidden technique of “explosive force.”

The sound of the third strike shook the forest. In comparison to the time before, this was much stronger. The tree trunk groaned one last time as the broken fibers broke with loud cracks. As the supporting point of the silvery thread, the trunk collapsed. Grabbing the thread with both of his hands, Kirei nonchalantly escaped the silvery ring at the point of collapse and pulled the thread apart link by link.

Irisviel knelt instantly as she felt the powerful backlash from the breaking of her magic. Calmly stepping forward in the manner of a victorious conqueror, Kirei looked into the despairing eyes of the two women and strode to the Calico, easily crushing its wooden frame with his hammerlike feet.
