Suì-Fēng's "zanpakutō" is . When released by the command , it shrinks into a stinger that is worn on the middle finger of Suì-Fēng's right hand. Whenever it stabs an opponent, a butterfly-like symbol called a spreads from the point of contact. The crest bears four wings because the Hornet has two sets of full-size wings located on its thorax. Due to her training, this mark can be kept there for as long as she desires. Should Suzumebachi stab the same location again, the opponent dies. This technique is called "Nigeki Kessatsu (弐撃決殺, Death in Two Steps)". This also holds true if an internal organ is pierced in the same location, regardless of the point of entry into the body. Furthermore, if Suì-Fēng is infected with a foreign poison, she can stab herself with her "zanpakutō" to counteract the new poison with her own, neutralizing it. Suzumebachi's "Bankai", is a part shaped like a bee's stomach acting as a homing missile high in power with a part acting as a launcher with a sighting device, shaped like a mask. Holding this bankai makes her hard to move and the thunderous recoil needs something like a or someone to reduct. Suì-Fēng notes that normally she can only use her "bankai" once every three days without issue; using it more than once in a day, while possible, drains considerable amounts of her spirit energy. So even the second shot would exhaust her to the point where her speed and maneuverability would be seriously impaired which is anathema to her fighting style which requires high levels of both. Even without the weapon, Suì-Fēng reformed the secret art Shunko(瞬開), meaning she is strong in close combat.
