Story-The mangaka make it a very good sci-fri manga.He building it so good until us readers easily through into the world.The space ship,the ppl,the concept ,he took time to search the real shit out of it,so it can be logic ,but and the same time it is like very frictional.He just like bring us to the space, and it's incredible.Who never thought about travel to space?!LITERALLY EVERYONE had thought about it at least once when childhood.He just help us complete our little wish. 8.5/10

Art- The art is very good and can see the mangaka took effort to learn a lot of space things order to draw the amazing manga.I meant the back ground,the spaceships, the characters ,all of them is very good!8.5/10

Characters-The characters is the most things I like in this manga.It don't focus on one characters, every one have it own problems ,own story & their own development.And it turns up every time ,we can learns about some lessons from them.9/10

Enjoyment-Literally EVERYONE will enjoy it coz WHO NEVER WANNA TRAVEL SPACE or CURIOUS ABOUT SPACE?The mainly reason I like it so much coz each characters of it like REALLY ALIVE,their will tell us what kind of problems they in,and mostly the problems is the most common one & the most difficult to slove one.Like
What is our purpose?Why we do that?Should I concentrate on work and let others things go?How Can I let go the past?Is it unnormal and strange it someone art like a child,and coz he/she just don't art like a "adult"that society what? 9/10
