Review Detail of WoodenWindow in DXD: Golden King of Lucifer [COMPLETED]

The main character is overpowered, which is expected with wishes. What is stupid is how the MC does missiions for his syatem, then throws the people he saved to Rias Gremory with her doing absolutely nothing to deserve it. The MC was born as Rizevims grandson, so the Khaos brigade will know him anyway and Canon is shot to hell with him being Vali's twin. The grammar is mediocre, it's readable but there are plenty of mistakes. The characters are totally undeveloped. Vali ran away without us having read even one conversation between him and the MC, his twin. We know nothing about the MC's likes or dislikes, only that he believes in absolute strength. Rizevim is also not fleshed out at all, he seems ok for a villain, then does a 180 to make his grandson listening to him, then ignores him again. The world background is also ignored, someone who has not read Dxd fics would be unable to follow this fic, and there are no additions/changes or even descriptions to be found aside from the MC being Vali's twin. Hell even Rizevims background isnt mentioned in the first ten chapters.
