Nisekoi: Episode 12

The relationship antics continue as Chitoge starts to realize that she is actually in love with Raku. Kosaki's younger sister Haru, who wants to protect her sister from the supposedly-depraved Raku, gets added to the mix. Other highlights include the introductions of Hana (Chitoge's mother) and Paula McCoy (Seishiro's assassin rival) and Kosaki's brief stint as a magical girl.
