Twin Spica, Volume 04: 05/08/12
Twin Spica Volume 04 by Kou Yaginuma turns away from the drama and expense of building a special space suit to the actual training. Asumi and her classmates get to do buoyancy training, robotic arm exercises and a long ride in the vomit comet.
Weaknesses in the characters are revealed, like an injury in Asumi's left arm as well as more hints about the fainting spells Marika.
And at long last there's some explanation behind Mr. Lion. I like him as a mentor ghost. He connects the past and present day stories.
If anything, I wish these volumes were a little longer. I want more character development mixed in with the training. Right now it seems to be one or the other in each volume, and except for the first one, never both.
