I need help finding an アニメ i forgot the name of.

The アニメ is about two girls who i think are robots but i forgot. So because they are robots they live for a long time and time after time they change their appearance but there main Colors（色） are red and blue (i think). These two girls work for an organization who have other robots(i think again). So their job in the organization is they go on these 宇宙 ship things and fight in a 宇宙 like place. Also there is a 秒 season about those two girl's kouhai. And the two girls come out in the 秒 season too but in different appearances. And if possible could あなた 表示する me a 写真 of those two? Please i really wanna find that episode!!!
