This season was made prior to Black Troops (so quality is not as good). More importantly, it provides more details for:
1) Angel Yan's and Ge Xiaolun's journey in Freyja
2) Fall and aftermath of Juxia Fleet and Qiangwei's father's death
3) Fall of Angel Yan
3) How Angel Zhixin met Zhao Xin and loses her Angel's abilities
Some of the scenes were remade in Black Troops I.
It comes with English Subs. Not perfect, but should be readable to get the gist of it.
