As you already possess insect breathing (a derivative of flower breathing), you now fully embrace the legacy of Shinobu Kocho. You become a pharmaceutical and medical genius, you are also able to use wisteria in a multitude of ways. Such as hindering a demon’s regeneration, suppressing their extrasensory abilities, altering your body to host said poison, and much more.
You also inherit Shinobu’s keen intellect which allowed her to excel in combat, alongside her indomitable will, which kept her fighting against the Upper Rank Two Demon, Doma, while experiencing massive blood loss and the inability to breathe.
