Jiang Qi is an actor who also works as a screenwriter, and he loves creating characters.
So of course it's perfectly normal for him to change a character's personality.
But his inexperienced System doesn't know that. It gets fooled every day by his strange but seemingly reasonable nonsense, and believes that the character he describes is exactly the role he's supposed to play this time.
So why don't you look things up, System? Is it really wise to trust your Host so much?
Characters decided so far:
1. The devout believer Shirase
2. The life-saving Mori Ougai
3. The innocent Dazai Osamu
4. The Rampo-san who refuses to use deduction
5. The literary youth Ryunosuke
I'll decide when to start writing after I finish Bungo Stray Dogs. The order these characters appear in isn't fixed. I've just listed them here for you to see.
Theme: Changing a character's personality is one of life's great joys!
