How far will two siblings go to save each other? As Chizuna fulfills Kazuna's bloodthirsty cravings, she desires nothing more than to merge with his flesh and blood. But while the thought of joining with her brother seems satisfying, Chizuna simply refuses to drink his blood--Kazuna reminds her too much of father. Chizuna's unwillingness to feed off her brother has weakened her to a bedridden state, and Minase decides to withhold any further medication for fear of its dangerous effect. Will the next vampiric attack finally make her rest in peace?
