Mirai (PG)

Four-year-old Kun happily plays with a toy train set in the modernist home designed by his architect father. Grandmother looks after the tyke while his mother gives birth to a daughter, who is eventually named Mirai. Brotherly love warps as Mirai monopolises the parents’ attention and the boy lashes out by hitting his baby sister with a model bullet train. Tempers fray and a distraught Kun runs into the garden where he is greeted by a dishevelled prince.
