Born in a distant future, MIRU, a weaponless robot, travels across time to support people from different eras. MIRU meets individuals from different times and places, people who, despite their struggles, live their lives with determination. Through their encounters with MIRU, people take small yet meaningful steps forward. These steps, like the "Butterfly Effect," create waves of change, moving toward a brighter future.
