Island
6 chaps - A dark supernatural tale based on some horrific real life history. The art is decent, and it is one of the first manga I've run across where the Christian character's theology is relatively true to his faith. Like other faiths, we (sadly) have 'divisions' called denominations, and this character's overall theology does not represent The WHOLE of Christian belief, but he decently represents his own and many core beliefs we all share.
Emerald
Some decent twists and turns - has female characters that use their head to overcome.
Unmei No Oaite Wa?
ONE-SHOT - I love this story. It's a pure, light-hearted love story that is so sweet and you might need to brush your teeth afterward.
Waltz wa Shiroi Dress de
22 chaps [5*] - Book 1 of 2 (Book 2: Magnolia Waltz - http://www.mangago.me/read-manga/magnolia_waltz/ ) Between the two, one of the most touching romances I've run across.
