Review Detail of Bilal_Arshad in Highschool DXD: The True God of Destruction

So, author, I have read only a few chapters and these are my criticisms: 1. I don't see the MC having the devil bloodline relevant except connecting to Gremorys 2. The dialogues felt bland having no life in them, especially with Grafia 3. Rias and Grafia's characters are not captured accurately i.e. Rias is a spoiled girl who feels like talent is very important due to seeing her brother so learning from someone who seems the epitome of talent without some "character development" is unreal; Grafia also takes her maid duties to house Gremory seriously so becoming that close to MC, without first having to haggle to talk on equal grounds is also unreal. 4. Although the sudden friendship and crush with Rias Gremory feels forced, MC shouldn't solve others' problems, he can help them not do it himself 5. He is OP but does not feel OP, and how did he not go super sayan berserk when his mother was killed
