Wareware wa Uchuujin

One summer in the third grade, a quiet boy named Tsubasa meets Kyotaro, a boy everyone in the class looked up to, and the two become close friends. Within their small world, they share irreplaceable moments—until a small incident suddenly tears them apart. Spanning more than thirty years, this gentle, contemplative story invites the audience to reflect on the meaning of life through the paths their lives take.
