퀘스트/목록/나유타/후일담/열리지 않는 상자

There's something I need you guys to help with. I will be waiting for you on the beach.

Sealed Box is an optional quest that occurs during 후일담 "나유타의 별들에" of The Legend of Nayuta: Boundless Trails.

The quest is available after at the beginning of the chapter.

The key to opening the box might be where the admins were trapped. There's also the 'order that the seasons swapped'...
It looks like the box is finally unlocked! Let's take it to Master Orbus and see what's inside.
