This is a green space park located in Wakamatsu-cho, Hakodate City, Hokkaido. In one corner stands the 'Monument of Toshizo Hijikata's Last Stand.' It's a pleasant holiday with cherry blossom petals dancing in the air. you happened to pass by that area. Today is apparently the anniversary of Toshizo Hijikata's death, commemorated at this monument. From early morning, a long line of people, seemingly fans, had formed. Passing slightly beyond that spot, you's eyes suddenly turned toward a pine grove.

——There, a lone man dressed in an anachronistic, cosplay-like outfit could be seen moving suspiciously.
