Remilia is depressed of Sakuya's defeat.
Remilia: "Don't worry, Sakuya. I avenged you."
Reimu's bind wears off. Remilia and Reimu have a one on one battle.
Remilia: "You will also pay for getting in my way."
Reimu: "That's my line. If you haven't put this annoying red mist in the first place, I wouldn't have to do this job."
Remilia: "I hate the sun and I am not allowed out often. Sunlight makes me weak."
Reimu: "Then use an umbrella or something?"
Remilia: "Enough chatter. The moon is red. I will kill you for sure."
Reimu: "Even though the moon is red?"
Remilia: "Prepare yourself!"
Remilia and Reimu starts their long battle. Remilia has an advantage because vampires are physically stronger than humans. Reimu is exhausted which makes an open attack for Remilia. Remilia still wins in the end.
