And in-story, Ryu gets progressively broken as he develops more.
Brown Note: The "Banquet of Evil" violin solo drives a violinist into increasing insanity as soon as he hears it, and it's mentioned that a mysterious person is forcing three other people to hear it as well through cellphone calls. The reason? It was the favorite musical piece of a brilliant player who was handicapped and killed herself... after an horrible trap staged by the other four (it was actually three, because her boyfriend has never considered that this could lead to tragedy). Who end up murderedby the girl's fellow violinist and the aforementioned boyfriend. And had he not done it, they would've died at the hands of the girl's half-sister.
The Chikan: A whole episode centers on this type of delinquent. One of them attacks Kuniko in a train, and once she recovers from the incoming Heroic BSOD, Yukihira and Megu help her catch him.
Cut Short: The anime faithfully followed the manga and was on track towards greatness when it was cancelled at a point in the manga where the real story was hardly beginning to unfold, and we mean almost 2/3rd of the plot, leaving virtually everything in the air, and throwing in a Gainax Ending on top of that.
Cute Bruiser: Kuniko, when she stops cowering after someone else's back.
Faking the Dead: The businesswoman Hanayo Ichinose tried this to save her enterprise.

Hot Springs Episode: Two murders happen in onsens. Only one of these mini-arcs has fanservice, as Kyuu and Kinta first fail to get Ryu naked in the springs and then try to peep on a Sexy Secretary bathing on the other side... and end up beaten by Megu, whom they get to see in the nude. The incident is actually plot-relevant, as it drops hints about the murderer - said Sexy Secretary.
It's Not You, It's My Enemies: Satoru had to leave Kyuu and his mom when he started investigating Meiousei/Pluto, only watching them from a distance. The single time he attempted to approach little Kyu directly, he was kidnapped by Meiousei, and Satoru went all Papa Wolf on them and singlehandedly got his kid back. Few later, though, he was killed.
Manchurian Agent: Pluto does this all the time to its clients and its own agents as a failsafe. On the trigger, they'll kill witnesses, or themselves, or go insane... it's not pretty.
Also applied on several culprits, courtesy of Meiuosei itself. Basically, they give you the means to carry your revenge and keep an agent close as a monitor, but when said revenge is foiled, they force you to either kill yourself or murder the person who blows your cover. And if a Meiousei agent is captured by the police, another will activate some sort of trigger that will make them kill themselves as well.
Murder.com: Basically, what the Meiousei goup does.
