Miko - so easy Cirno can do it.

ps. kazehahuri doesn't count. Sanae is the greatest.

whats with all the cirno->reimu cosplays

In some respects, Cirno is already part of Reimu's growing harem (not as large as that of Marisa, but still... also Reimu herself is part of Marisa's harem). Others in the Reimu harem include Marisa herself, Alice, Yuuka, Aya, Remi, Sanae, Suika, and Yukari. Many more may even come...
