What's with the word count? I blinked and it's all over. Which is annoying since there's barely indication that time has passed, or how it's passed, between events. Putting in lots of action to jumpstart the story didn't help either.

Being frank, I'd give this 2/5 if I forgot this is WN and focused on its flaw. The premise is good, and I assumed the author will eventually learn to balance it with exploration and pacing.

Hello, Advent of Null MTL here.

My first completed series! ≪Title> is a story about a big brother trying to change his sister, who devolved into villainy, after reincarnating into a game world. It's not a power-fantasy isekai. It's a shonen drama. A lot of fights, a lot of onomatopoeia, and of course a touch of plot armor.

Sometimes it's strategy, sometimes it's foresight, sometimes it's trickery and outplaying the enemy, and other times it's a mindless brawl. Sometimes, it's a touching story about family and familial love. It drags on in... more>> some places, but as a whole, it's short and sweet.

For an "amateur high school writer", it's not bad at all. Give a star or two on the kakuyomu page and make it go over 100 stars. It's their listed goal on their bio.

3/5. Special place in my heart. <<less

Pretty bad. Just plain bad. The tone of the story is serious, and yet, the story already jumped in the argument of the characters.
For a serious story to work, it should first give context to the main character and its side characters, as well as establish a proper personality for every characters so that we could know whether they are likable or not. There's nothing like that here, it's already a conflict from the get go.
