This is a really interesting story so far! I like the similarities between Ryuu and the MC before he fell into the "rabbit hole" (they both have a little sister that worries about them ^~^)! The writing is phenomenal, there wasn't any grammar mistakes at all! The writing and story flows very smoothly, and the pace is really nice~ I like that it's in 1st POV, something I haven't encountered before in WN c:The update stability is also really nice, it seems to be updated every 1-2 days which is awesome, especially for a new book! Very interesting story that people should check out if they like the science fiction genre~ Hoping for the best!
