Lost Mask

The Lost Mask is a key item for unlocking the character, Hata no Kokoro. It can be found around the map once every hour. It is recommended to wait in a private server for it, as usually someone else will end up getting it. The item is one of the rarest ones in the game, and cannot be dropped.

You are able to find the Lost Mask behind rocks, the ZUN rock and the grassy path behind the Hakurei Shrine
