Kuma-Ken (クマ 拳) - "Bear Fist."
Bear Fist!
Musubi's first named attack, learned during her fight with Katsuragi. After Homura's emergence, both Musubi and Tsukiumi demonstrated new attacks with increased power, presumably this is due to Minato's increase in strength as an Ashikabi.
While executing the attack, Musubi manifests a dark red shroud of aura shaped like a bear, similarly to Miya's manifested hannya, some of the aura is then transferred to Musubi's fists. It then changes colour to a bright pink as Musubi leaps forward, slamming a devastating punch, typically right-handed, into her opponent's torso.
After Musubi first unlocks the technique, the Kuma-Ken is typically shown in subsequent uses as an energy-enhanced punch, without the theatricality of the first use.
