Nisekoi:

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.
