A Boy Who Fishes Dreams
Definitely could be made into a longer series.
Onigami
More chapters, more chapters!
Sword Dancer
I'm certainly looking forward to Ninagawa-sensei's future works alright!
Blood Type V
So much potential, all gone to waste on just a oneshot...
The Rose Princess's Awakening
I find it so surprising how complex the story is, it's backstory and the political play of its present. Then you have memorable characters, even those who never actually appeared outside of memories alone. I really wish there was more of this story, I think I could probably read it even if it was 30 chapters long.
Teki wa Ousama
As expected of this mangaka, I loved the art. The story was hard to understand though, I can tell it probably is kind of cute or sweet, but the translation was so terrible that I really couldn't make sense of what people meant to say. What I could understand was: Rich boy and farmer girl meet at a party, their grandparents seem to be friends. The kids get along so well, that the boy gives the girl something very precious of his so that in the future they can meet again. 5 years later, girl finally goes to boy's school, just to find the boy be a completely different person than before. No matter what the girl does, boy is very mean to her, repeating that he just wants to forget about the past and her. He even throws into the river the precious object he had given her 5 years ago. Somehow girl manages to get to his heart or something, and he helps her find the precious object. Everyone seems to be happy as she rides the bike he stole while he's just sitting on the back doing nothing.
