Chi Komori, Yui's sister also went to the Sakamaki mansion with Yui. Ever since she went there she started to change and not for the best. What happens when she falls in love and who will she fall in love with? "Do vampires get boners?" "But what if penguins can fly but the government doesn't want us to know" "If something bad happens blame the government" "what why?" "Uhhh because they touch themselves at night" (I don't own Diabolik lovers, only Chi and the plot twists)
