Really good. I like how the characters are developing.

Good. He feels real. But at around middle of the story, he forms a harem which is very messy.

I am waiting for him to go back to Harry potter world. After all he's from there and Hermione is still missing. Besides he already knows so much magics and has a solid foundation. Can't he just research and improve on his own.

thank god

Not bad. But it is slow. The superpower are not unique. but the world is interesting. Waiting for more.
