The task of choosing a young girl with the power befitting that of a Hakurei's Shrine Maiden fell into the Kirisame's hands.

Ah, that wasn't a complaint, mind you. It was just that, at the time, the Hieda simply didn't have any excellent magic users.

I'm well aware.

I only wanted to observe and confirm the information by myself.

I wanted to see what kind of person the Hakurei's Shrine Maiden is.

What kind of person the Guardian of Gensoukyou's most important barrier is ?
