past person time travels to modern story line, anyone?

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

Is the second one completed?
