Reiatsu Explosion

 is a technique used by the manifested spirit of Ikkaku Madarame's Zanpakutō, Hōzukimaru, while using his Bankai, Ryūmon Hōzukimaru.

Description
Grabbing the central blade of Ryūmon Hōzukimaru and raising it over his head, Hōzukimaru rapidly spins his Bankai, creating a powerful whirlwind in the process, before slamming the central blade into the ground, creating an explosion of red Reiatsu which can blast other combatants away. Hōzukimaru can use this explosion to mask his escape from the battlefield.
