Nanatsu no Taizai: Seven Days - Touzoku to Seishoujo

A spin-off of *Nanatsu no Taizai* that expands on the meeting of Ban and Elaine. In a region north of Britannia lies a forbidden forest, the "Fairy King's Forest," where humans are not permitted. The Fairy King, Harlequin, has been absent for 700 years, leaving his younger sister Elaine to protect the Fountain of Youth alone. After centuries of solitude and repeated separations, Elaine's tears are nearly spent. A young man named Ban arrives, searching for the Fountain. Over seven days, Elaine's heart begins to heal, and the gap between them narrows, though challenges remain.
