Hmm, This novel wonderful, but it doesn't suit my taste, but it is great that i would put it in my list of favorite novels.
But what I like in your novel the most, was when the argonaut raided the althaus state or mansion, I love on how you put details that made me imagine on what really happened, but sadly it was too fast, I didn't get to enjoy or to see the suffering of the servants in the mansion, but althaus gets the worst fate so much suffering and such traumatizing event have happened to his servants, such a scary experience but I want to see more.. but it would a false hope to hope that you will add more of it in the arc, but hopefully I would get to read more of it in the future, hopefully...
And yes your side characters/characters, such a splended work they have such a wonderful personalities, I like them hope I could meet some crazy characters, I could put some of my reviews on the characters but they're quite many so I'll pick only ren to review on.
ren is such a lame character I hate him and i love him, his such a well done Character that made me hate him, his naive a fool and a trustful person and a lustful person an awkward Character that made it hard for me to read his interactions with other characters, but his a great character that can be easily manipulated and easily changeable, that he put so much trust on a girl that summoned him that easily betrayed him, his such a fool that I like him, the girls action made him distrustful of other people, hence his such a changeable and easily manipulated, his such a fool that he trusted a girl that summoned him into this otherworld, and I don't want to spoil other readers so I'll stop here, but I get it that his a manipulatable person it happened alot in the real world, so his a nice character his such a normal person I like him.
The story so far is great but the development of the story is fast it made me bored of reading it cause things happened fast, but for other readers the story has a normal a phase of development, but for me it's fast, but I saw nothing wrong in the story so far.
For the the writing quality I don't know, I've never seen some wrong spellings or typos, English is not my first language after all, and the updates of chapters is fast I like it.
I'll end my review here I can write more but I think this is enough.
