Lunar Legend Tsukihime, Vol. 5

After rescuing Shiki from his dangerous encounter with Roa, Ciel warns him in vain to stay away from Arcueid, who may have an ulterior motive. Meanwhile, Shiki cannot shake off the feeling that he knows Roa, and a visit to the garden of his house jolts his memory, piercing him with visions of Roa as a child, along with a voice telling him that he will become a "true monster" someday.
