Ryūko Tsuchikawa operates as the Pro Hero Pixie-Bob, a founding member of the rescue-oriented hero team Wild Wild Pussycats. Her hero name references the Pixie-bob cat breed, aligning with the team’s feline motif. She established their hero office and crafted their identity, with the group active for over 12 years since their high school formation. Specializing in mountain rescues and disaster response, they held a #32 national ranking before a hiatus dropped them to #411; public encouragement prompted their return. They mentor U.A. High students, including summer training camps and preparing Class 1-A for the Paranormal Liberation Front conflict. Ryūko originates from Ehime Prefecture. Ryūko possesses a slim build, long swept-back blonde hair with bangs, and blue eyes. Her costume includes a light-blue paw-pad-accented minidress, a tail, tinted visor, cat-ear headphones, and two blue cheek dots. She displays hyperactive, loud tendencies and disregards social perceptions. Deeply self-conscious about aging, she insists she remains "eighteen at heart" and reacts harshly to age-related comments. Her impatience for romantic love has intensified. Despite eccentricity, she comforts Kota Izumi about his parents' death and supports Ragdoll after her Quirk loss, while humorously "claiming" young heroes like Izuku Midoriya, Katsuki Bakugo, Tenya Ida, and Shoto Todoroki as future romantic interests. Her Quirk, *Earth Flow*, telekinetically manipulates soil and rock across a wide radius, forming constructs like walls, trenches, or animal-ability-immune "Earth Beast" golems. This power reshapes terrain for rescues and combat but requires direct soil contact and fails in earth-scarce environments. *Earth Beast* serves as her signature technique. Hero registries rate her Power B (4/5), Speed C (3/5), Technique B (4/5), Intelligence C (3/5), and Cooperativeness A (5/5), with later improvements noting Power A (5/6) and Technique A (5/6). She is a skilled martial artist and cook, producing meals rivaling Lunch Rush’s. Ryūko aided against Bomber villains at Captain Celebrity’s Tokyo Sky Egg farewell show. During the Forest Training Camp, she launched Class 1-A’s training by submerging them in her "Beast Forest" Earth Beasts and disclosed Kota’s orphan status after his parents (Water Hose heroes) died on a Pussycats mission. Magne deemed her the team’s most dangerous member during the League of Villains attack, knocking her unconscious and inflicting head trauma; she recovered post-hospitalization. After All For One stole Ragdoll’s Quirk, Ryūko consoled her, leading to Ragdoll’s fieldwork retirement; the Pussycats briefly halted operations before resuming with Ragdoll in support. At Jaku Hospital in the Paranormal Liberation War, she assisted evacuations, fought Nomu, and attempted containing Tomura Shigaraki’s *Decay* with earth barriers before Tiger’s forced evacuation. In the Final War at Gunga Mountain, she erected earth defenses against Himiko Toga’s Twice doubles and Dabi’s flames, later burying Fumikage Tokoyami to amplify his Dark Shadow against All For One. Her journey reflects resilience through team struggles and unwavering heroic commitment, utilizing her Quirk for rescue and combat.
