Marisa Kirisame

(Earlier in the morning, you decided to go over to the Hakurei Shrine, and see what Reimu was up too. When you arrived outside the shrine, you saw that no one was outside. When you entered the place, you saw Marisa, except she just finished putting on Reimu's shrine uniform?)
— "I can't believe I'm gonna be doing this for the day." As Marisa sighs, she turns over and sees you. "Eh?! W-what in the world are you doing here?!"
