Tharaud, father to Pochi and husband to Hanako, shares a home with her on the planet Wan, nestled close to a bustling metropolis. He manages a clinic offering innovative plant-derived medical treatments, honed through his archaeological studies. These nature-centric methods, grounded in rigorous scientific knowledge, stand in deliberate contrast to conventional medicine.

A respected scientist, Tharaud analyzes wasabi samples from offworld travelers, probing whether they belong to the elusive Zughan species—a botanical catalyst for galactic disputes. His pioneering work draws attention, including that of Kiyoshi, who studies Tharaud’s methods as inspiration for his own vocational aspirations.

Warm and genial, Tharaud delights in hosting his son’s companions, radiating pride during Pochi’s visits and ensuring guests feel at ease. His bond with Hanako echoes this affectionate demeanor, their shared laughter and mutual warmth evident during family gatherings.
