Mori ni Mamorareshi Shinden ni Matsu wa, Ai

A girl woke up in the middle of a forest with no memories.
Looking at her were two brothers. The elder Gaiya and the younger Shing.
The two had come to the forest for some reason, but they couldn't find a way out.
The girl takes the name Rachael and takes up the mission to get out of the forest, taking down enemies with a forgotten magic.
The two brothers feeling that Rachael is the key to escaping go along with her.
--This is the story of how Rachael completes her mission.
--And a small bit of love that might bloom while interacting with the brothers.
