Kazuha received his Anemo Vision while he was spending a night at his house.
His acquisition of the Vision occurred spontaneously during an evening at his residence, marking him as a wielder of the Anemo element, associated with freedom and wind. While theories often suggest that Anemo Vision bearers are chosen following the profound loss of someone close, Kazuha's specific circumstances did not align with this particular pattern. His Vision simply manifested during a quiet night at home, highlighting the unique and often mysterious criteria through which Visions are granted to individuals in Teyvat. Each Vision story, including Kazuha's, stands as a distinct testament to the diverse paths that lead to divine recognition.
