Exploding Heart Release Fist

Explosion Release Fist (爆心解放拳, Bakushin Kaihō-ken) is a martial art primarily used by Bang before developing Water Stream Rock Smashing Fist.

This martial art is one of the 12 main fighting styles that make up the Monster Calamity God Slayer Fist.

Overview
Before inventing Water Stream Rock Smashing Fist, Bang used Explosion Release Fist as his primary fighting style. Unlike Bang's current fighting style, which is defense-based and focused on redirecting attacks, this martial art is instead oriented around brute force and destructive power, pummeling opponents into submission. After being defeated by Bomb in his youth, Bang chose to abandon this fighting style and instead develop Water Stream Rock Smashing Fist.

Bang kept the scrolls detailing the techniques of this style hidden in a safe in his dojo. However, Garou broke into the safe and learned about this fighting style. After becoming a half-monster, Garou eventually became capable of mimicking this technique and even overpowering Bang, though Bomb noted that Garou's usage of the technique was still incomplete and inferior to Bang's.
