Iroha ~Aki no Yuuhi ni Kagefumi o~

Deep in the mountains lies an old village where Riku lives peacefully with the veterinarian Waka and his pet cat. One day, Waka returns with a small girl named Yuna, who has lost all memory of her past. As she stays with them while they search for her parents, Yuna's innocence stirs something in the quiet community, hinting at secrets hidden in the autumn twilight.
