Whirlwind Iron Cutting Fist

Whirlwind Iron Cutting Fist (旋風鉄斬拳, Senpū Tetsuzan-ken) is the school of martial arts practiced by Hamada Kaoru

Overview
Chikoken (地功拳) is a Chinese combat technique also known as Ground Boxing that essentially relies on movements from the ground. Whirlwind Iron Cutting Fist combines this with aerial moves enabling the user to fight in a 3D space as opposed to a 2D one by using the ceiling and even opponents body as stepping stones. Although the style can grant a skilled user tremendous mobility, it is a demanding art that requires strength, and skill, both of which must be honed through constant practice. Whirlwind Iron Cutting Fist Is a fast and versatile martial art that allows humans, which are limited to two-dimensional movements, to adapt to movement in the third dimension. Due to this opponents find practitioners surprisingly hard to defend against in a melee combat as they weave through difficult and fast obstacles quickly using their head, fists, elbows, knees, and legs, as offensive weapons. Great physical strength, particularly in the legs, coupled with spatial recognition abilities, as well as the mental strength to not waver in the midst of a panic, are crucial qualities to master this style.

Trivia
This style is based off Fist & Footwork of Earthen House from Veritas combined with Attack on Titan’s Vertical maneuvering equipment.
