Mob Psycho 100 Season 2 didn't complete the manga. The season focused on specific story arcs but left out some significant plotlines and developments from the manga.
To a large extent, it is. The show takes inspiration from actual cases and tries to present a realistic account. However, there might be some artistic liberties taken for dramatic effect.
Season 2 of Dr Death is indeed based on true incidents. The creators have done research to bring those real stories to the screen, while adding some dramatic elements for entertainment purposes.
It's not straightforward to pinpoint exactly where Dr. Stone Season 3 ends in the manga. Different factors like pacing and story arcs can influence it. Usually, you can look for key plot points or consult fan discussions for a clearer idea.
šI recommend the following two novels to you:
1. "Get Dressed: Your Male Lead Has Fallen Again": The male lead of this sci-fi space-time travel novel is a psychopath, and a paranoid big monster. The female lead was pestered by him and had no choice but to deal with him. Both the male and female leads were sick, and the male lead would turn evil. The main tone was sweet and pampered, with a little sadistic seasoning.
2. "Villain Rely on Acting Coquettishly": The male protagonist of this sci-fi space-time travel novel was also a psychopath, but he was a coquettish little sweetheart who fell in love brainlessly. The female protagonist, Yumu, was helpless against him and refused to divorce him. The entire novel was humorous and sweet.
I hope you like this fairy's recommendation. Muah ~š
