shifted her energies towards voice-over work, and that her experience with dialogue and Shakespeare classes helped a lot towards landing roles that involved various characters, some of which had accents or were from certain time periods. Anime work Wahlgren's debut anime role was Haruko Haruhara in a six-episode OVA series called FLCL. In an interview with Anime Tourist, she said that Haruko was the only character she got to audition for. She depicted her as close to the original dub but with some American interpretation to appeal to the audience, and depending on how she was drawn, she changed her voice range from cartoon and childlike to realistic.
