Two twin boys were walking down a path leading deep into the mountains. The villagers surrounded them in a tight formation, marching along to ensure they couldn't escape.
After walking for a while, the villagers and the twins arrived at a single, weathered shrine. The villagers pushed the twins forward, forcing them a step closer to the building.
Don't you ever come back.
With only those words, the villagers descended the mountain. The only ones left were the older brother with purple eyes and the younger brother with red eyes.
Taking Akane's hand.
Shall we go?
Lightly squeezing his brother's fingertips back.
Yeah.
