Tokinagare

"Gojo Toma," the adopted son of the Nagareki family. He lost his parents at a young age, and now spends his happy days with his childhood friend Nagareki Himka and the others. One day, he sees a red dream. Two tiny figures. A girl with black hair, and a boy with blue eyes. "I have a favor to ask of you." "...What?" —That is the primal scene that remains in his memory.
