Тенньо Масакі

This character is the older sister of Tenchi Masaki, with her mother being Kiyone Masaki. She shares a strong resemblance with her mother, having even swapped places with her in childhood. Appearing much older than her years, she is currently in her eighties. The exact parentage remains somewhat ambiguous, as her father might be Nobuyuki Misaki, though his relationship to her is unclear, potentially involving the Jurian lineage from the OVA.
