Red storm

Art is really good and each character has a unique story and personality which really brings the manga to life. The story is also good but there were like 100 chapters or something that were only about large scale wars which bored me a bit. Almost at the end after these were all these wars were finished I thought the mange was picking up again story wise but then it ended weird and left a lot open which was really a bummer after reading 388 chapters.
In chapter 388.5 the author said he would make some side stories taking place after this manga has ended so that would probably answer most questions and finish the weird open ending but the author is first working on another manga called peerless dad. There is thus no indication when these side stories will be released.
