[Machine Translation] In a world where girls fight as "weapons" to replace "violence". Rain's heart cannot follow the truth about Hana, and he is unable to face her straight. Regardless of her feelings, a heart-moving car carries the two girls who were defeated on the battlefield back to the "Iron Country". However, the car carrying the two girls suddenly stops, drops off one girl, and starts moving again. Don't stop... Don't leave me... Rain, who has been separated from Hana, sings and dances alone as a "tool" while worrying. On the other hand, Hana, who was separated from Rain as a trainee, also has feelings behind her smile that she did not know she had... In the dark and red "Iron Country", Hana is not with Rain. In a world where there is no "girlfriend" next door, girls searching for Kirakira weave a story of bonding and love.
