As a certified weeb, Inês always dreamed of visiting Japan one day. She never imagined Truck-kun would grant her wish: after being hit by an ice cream truck on her way home one summer afternoon, she wakes up in snowy, Sengoku-era Japan! There, she meets other Japan-obsessed teens like her. It’s almost like a dream, let's hope it doesn’t turn into a nightmare…
Soon, they’re recruited to defend the realm as the Shining Hearts Sentai PurePure! But as their bond strengthens and their powers grow, Inês and her new friends face their greatest challenge yet: an illusion they desperately want to believe.
