This novel is a nationalistic rebirth story where the protagonist becomes a manga master. The later part of the story is quite enjoyable. However, a major drawback is that the female lead has romantic feelings for her own brother, and later on, the brother also abandons his moral principles and reciprocates her feelings.
It even goes so far that the female lead secretly draws 18+ doujinshi... it's likely about Yosuga no Sora, though I'm not sure, but it's definitely a story about a younger sister being in love with her older brother.
The only positive point is that the ending doesn't explicitly reveal the nature of the female lead's relationship with her brother.
P.S. The author also seems to agree with the idea of loving someone within the family, WTF.
The best female protagonist in a dungeon horror novel I've read so far.
She's eccentric, insane, and selfish, not annoyingly kind. She tends to view fellow players as souls that may or may not help her. If there's a benefit, she'll assist, but if it's troublesome, she'll ignore it. And if she sees players she dislikes or who cause trouble, she can kill them off.
P.S. Since there's no CP (couple pairing), 5 full stars.
