I honestly don't know what it is about Demekin that feels a bit superficial tbh. Something about the relationships is very surface level but it's entertaining for the most part. It was mostly about friendship between the two main leads but I felt like they were not very expressive toward each other in the right way, they kept saying a bunch of stuff but you don't feel their bond. They just didn't do it right imo so it just fell flat on the whole. Over Drive with Mackenyu suffers from the same but at least the way Over Drive is made is very entertaining and especially Mackenyu not only sold me on his character but you see that love hate thing going on in his eyes, so you feel it too. But Demekin was very trite and even annoying in places. But the final showdown that was done well and so is the violence and most of the action so like I said, it's not terrible either but you won't be missing anything if you didn't watch it.
