It's so cliche for the guy to transfer to the body of the protagonist, villain or supporting character. The idea of soul fusion is more interesting and far less used. As you don't want to read this story and no one is forcing you I'll even give a Power stone to the story just for not having a troll like you as one of the readers

In the first chapter of the story you are already dictating what will happen. Are you the author? If not, how can you say that this will all happen? Do you know how to give constructive feedback? Or just had a bad day and want to take your anger out somewhere?

From what you understand this Forgotten Realm is like The Gamer's dungeons? Time goes faster, there are monsters and maybe the monsters drop items?

judicial process?

This is a fanfic with a lot of potential. So far the MC has made many rational decisions like suing Issei and Matsuda, getting access to a virtual library full of magic books and much more. It is interesting that the MC is slowly developing without drawing much attention to the results. He's the type that people think is weak, but secretly he's getting really strong. As the author himself said English is not his first language (nor mine lol), but he is doing his best to bring huge chapters almost every day.

This chapter is very good. The idea at the end of Motohama having switched places with one of his shikigami clones was very good. If he received the memories of the destroyed Shikigami he could use this method to train, study, learn spells and much more.

I really liked this idea of mixing DXD with Strike the blood. From what you can see, maybe humans have a bigger role in this fic. It was boring just to see fanfics in which the MCs are demons, angels or hybrids with dragons

This Motohama's mother reminds me a lot of Miya. I liked the ideas used in this chapter. Interesting use of shikigamis. I also really liked Motohama's skill.

I really enjoyed the chapter! The idea of putting a process on the two groups of demons makes sense. Making a formal record doesn't give them the chance to erase Motohama's memory without anyone knowing

The plot is very forced. The protagonist needs to have a better development in his personality. The author is clearly a fan of Issei, but tries to make him a better person which makes the story dull. The system itself is a system of sexual harassment at the very least and can lead to rape. It doesn't have much use other than picking up girls and has little presence throughout the chapters.

I give up. There are many points I could mention, but the changes in the characters' personalities are very annoying. A boy comes out of nowhere and beats Sona at chess? Besides being a cliche, it's pretty hard to believe. The change in Issei personality made him even more boring than he already was.
