Hello there, this is my review of KH: Days, and you're allowed to have your own opinion. :D
Story: 10
The story is complex like everything in the KH series. It has moments that will make you laugh, cry, and feel all of those fells, so it has fast paced parts and slower scenes. This story is dark and sad since of it questioning and addressing very serious matters like death, existence, friendship, betrayal, etc.
Art:10
This manga has brilliant art. Every Disney world feels unique, and the characters all look amazing. The artist paid attention to every single detail, making this beautiful to look at. You can see all the effort put into this manga by the art alone.
Character: 10
All the characters are wonderful in here expect for Vexen, but Vexen is barely in here. To just name a few, this manga has the well-written characters of Roxas, Axel, Xion, Riku, Naminė, etc. The three mains are very relatable as well. For example, people can easily relate to just wanting to waste your days away while eating ice cream with your best friends.
Overall: OVER 9,000!
This manga has good things going for it, and I recommend that you either read it or buy it. It is recommended to read the prior parts of the series before this one though.
