Editor Profile

さすらいトキヲ Tokiwo Sasurai
Former magazine writer and web editor. I develop articles around the everyday questions and social issues that make me stop and ask, “Why?” I use AI as a supporting tool for research, organization, and image creation, then review the content before publication. Each article is edited with my own experience, observations, and perspective added to the final piece.
