Thorough searches across the anime "My Patrasche" — including adaptations titled "A Dog of Flanders: My Patrasche" and "Flanders no Inu, Boku no Patrasche" — yield no trace of a character named "Boman." Production credits, multilingual cast lists for Japanese, Italian, French, Spanish, and Tagalog dubs, and episode guides omit this name entirely. Documented character descriptions and voice actor roles exclusively reference figures from Marie Louisa de la Ramee's original story, like Nello and Patrasche. Consequently, no official details about "Boman" exist in available records for any season, adaptation, or spin-off of the series. No info.
