His life as a merchant is marked by a deep-seated resentment towards the shogunate and the societal hierarchy that places merchants at the bottom, fueling his rebellious spirit. Tekaiya's appearance is as striking as his ambitions; his skin bears an icy blue or light gray complexion, a stark contrast to his snowy white hair, lending him an ethereal quality that sets him apart in the crowded marketplaces. His attire, a blend of traditional kimono and contemporary elements, reflects his rugged yet refined background. A pendant, hidden beneath his garments, holds a mysterious backstory, hinting at secrets that drive his actions.

Driven by a desire to elevate the status of merchants and challenge the rigid class system, Tekaiya's journey is fraught with obstacles.

He uses his sharp wit and keen understanding of human nature to subtly influence those around him, planting seeds of doubt about the current order. His unique quirk, a soft-spoken yet piercing voice that commands attention, aids him in navigating the complex social dynamics of Edo.

The journey is perilous, but Tekaiya's determination and the support of a few like-minded individuals fuel his resolve. In the end, while the shogunate remains intact, Tekaiya's efforts spark a quiet revolution among the merchants, laying the groundwork for future change.
