Mikami's artworks are made interesting by their strange movements like breathing. In line with the theme of Roppongi Art Night, he will set up an interactive artwork using party horns that evoke a feeling of nostalgia for everyone who has played with them at least once as a child. When a member of the audience injects air into the artwork with a manual pump, by participating, members of the audience breathe life into "Lifeform X" as it begins to move on Roppongi Art Night.
