In the parody special *Shakugan no Shana-tan Returns*, Kazumi Yoshida appears as "Black Yoshida" or "Black Yoshida-san," embodying malice and jealousy starkly contrasting her main series' shy kindness. Her signature declaration, "I'll kill her," voices intense irritation toward Shana-tan and envy over Shana-tan's interactions with Yuji Sakai. Obsessively fixated on Yuji, she relentlessly stalks him and Shana-tan, often concealed behind telephone poles bearing "Reserved for Yoshida" signs near the school or Sakai residence. She entirely disregards Hayato Ike's romantic confession, focusing solely on Yuji. Her appearance amplifies comedic traits, notably pride in her large breasts, which she jiggles or artificially enhances in attempts to seduce him. A recurring gag involves repeatedly losing dogs named Ekaterina, each meeting a comically explosive end; this provides excuses to visit Yuji's balcony, with Yuji noting each dog's differing appearance. While maintaining a polite facade before Yuji, she openly plots against Shana-tan in his absence. Her role presents exaggerated jealousy and dark humor, a departure from her original narrative.
