They are all comedy.
1)The Reincarnated Little Mermaid Does Not Want to Disappear as Foam
2)The Struggle of a 0 Love Flag Girl /Renai Flag Zero Joshi no Meisou (one of my favourite's)
3)Romantic Killer
4)Touch My Little Brother and You're Dead /
If You Lay a Hand on My Brother, You're All Dead
5)The Eccentric Duchess
