My review as of 15 chapters:
A decent manga, story about MC and his friends doing their bucket list about 100 things they want to do while alive in a world full of zombies. Started very strong and fun but as the story progresses (if it has any), it becomes more and more bland and hollow, at one point it just decides to be "Yea, screw everything and let's have fun". If you are looking for a manga that you can put your mind away and have fun, this manga would give good entertainment, but for me I started to skim through after chapter 5 or 6, didn't care enough to read all dialogs. Not a 9 or 10 in my book, but rather a 6 at most, it is not bad just feel very empty reading it, if anything I would say the art is amazing.
