It could totally be a reference! I do remember one of the CP9 agents had a thorny whips though. I feel like I've seen other fodder characters use a thorn whip before, but I could be mistaken.. Kurama takes out a rose, and uses a technique called bara toge muchi ha (rose thorn whip blade) to create a whip covered with thorns, which can slice through steel. He uses a technique called kagon retsuzan shi (luster severe rending slash limb) to slice Genbu to pieces, but Genbu is able to pull himself back together.
Rosewhip is a thorn-based personal magic. It is used by Shuen Getsuku. Rosewhip allows the caster to transform their wand into thorned vines and use them to attack and/or defend.. Rose Whip (薔薇棘鞭刃 (マニピュレーション) , Rōzu Uippu?, lit. Rose Thorn Whip Blade) is Kurama's signature Demon Skill that transforms a single rose into a powerful whip with cutting-edge thorns. This move is a simple transformation technique that uses Demon Energy to change a harmless rose into a long thorned whip that can cut through solid rock and steel. Kurama uses this.
