Koi☆Sento

The two have a similar art style, colour palette and directing as well as the male protagonist in both are very alike in their personality and character design. Both use a fair amount of computer generated (3D) animation and contain themes of love and sci-fi. 

• In both the romantic anime a mysterious girl who is running for her life is being saved by a boy. • The MCs in both the anime have similar dynamic.  

Both of them are short romance stories where the main characters are helped by an animal. 

Meeting a strange or mysterious girl who is in trouble is fairly regular event in anime. The male main characters in Typhoon Noruda and Koi☆Sento find themselves in this very situation. Oddly enough, they are both smitten by these girls and decide to rescue them. I wouldn't describe these anime as good, but maybe you're interested in watching the early works of the staff associated in these titles or maybe you're looking for short some anime. Either way, you know what quality to expect.
