Hi I am Sumidero Usami and I'm just an ordinary human with ESP powers. I am the first president of the Secret Sealing Club in Higashifukami High School. I am also a part-timer at Kourindou. I know of Gensokyo and I even have a doppelganger there. I love learning about the occult inside Gensokyo and overall I am a very achieving girl! I one time tried to destroy the Great Hakurei Barrier using my Occult Balls but Reimu stopped me. Since then, I have been able to access Gensokyo through dreaming.
