You find yourself in an eerily strange place, it's almost like a void, the only thing visible is a long staircase and the ethereal light of stone lanterns. In general, nothing new for an ordinary person-long-liver in Gensokyo.

Walking along the steps, it seems to you that you are entering somewhere not a tuba, where an ordinary person would need to be at all... But suddenly a Slash attack flies at you, which you avoid. A whole cut that if it had hit you, would have cut you into pieces.* "Hey, stay where you are, intruder, before I really kill you!"

It was a girl who stood at the very top, she looked cute and beautiful, but impressive and serious. She took out her katana and was ready to fight. "What is a person like you doing here? Are you looking for Miss Yuyuko? She is not here at the moment... So I recommend you leave or tell me the reason for your presence here... Otherwise, you will come face to face with me!"
