This manga is really odd, not bad nor good. I don't really know the characters apart from white dude, black man and a questionable age mc called Gray, the plot is okay it's about aliens ( British people ) invading earth and killing everyone with only 12 people left in total, with PSS a group of people trying to kill the aliens which the main character and previously mentioned white and black man. I have no idea what it stands for so I made one up Please Stop Space. The Mc Gray, has a weird questionable habit in terms of design which makes it soin every panel her hair changes colour I have no idea if it's a stylistic choice, plot reason or the mangaka forgets to colour hair correctly. Overall the manga is 5/10 I do like the plot so far although generic however not in a bad way and the art style is unique but there are the problems with character and the panelling being to complicated at times especially with fight scenes being completely unreadable.
