A depiction of Touhou 15.5 this time. It's a fighting game.
STORY: One quiet day in Gensokyo, too much spiritual power was being taken away, and even physical power. Anything electrical wouldn't work, in fact, people fainted very easily. If this continued any more, everyone in Gensokyo would die. People in Gensokyo notice a strange power coming from the east, and decided to head there and investigate.

Eiron was a young child from a properous family. She was relatively faithful and worked as the priestess of a temple, the Kanmeiji. However, soon, her parents abandoned her for some unknown reason, causing her to emotionally lose control. She traveled along deserted roads until suddenly, someone welcomed her into a border, which lead her to Gensokyo. There she would make new friends.
Due to her new immense power, to manipulate spirituality, her human body could not handle it and she became a half youkai. Eiron didn't mind; it would come in useful.
Used to being in a high position, she opened up her own kingdom, desipte how young she was. She called Oraple, a mix of 'Purple and Orange', her favourite colours. Many people were quick to join and Oraple was successful. She became respected for giving everyone a new home, she was named 'Mikorin' (lit. Child of God's Phosphorus).
During Touhou 15.5, her temple was literally 'shut down' for no reason, forcing Eiron to head out and save her kingdom.
