What is happiness? Ever the fan of psychology, questions such as this are ones that high school student Ritsu Shikishima likes to ponder as he spends his peaceful days with his friends. His perfect world, however, begins to unravel when he hears a strange voice obscured by static, pleading for help. This voice belongs to μ, a beloved pop idol, whose singing begins to have an adverse effect on the world. Before Ritsu's very eyes, the faces of his friends and family become distorted by glitches as the sound of μ's voice transforms them into Digiheads: berserk monsters bent on the extermination of all those who begin to awaken to the true nature of their existence.

Realizing that he is trapped in a virtual world created by μ called Mobius, Ritsu must now gather everyone else who has managed to realize the truth before they are all eliminated. Together, they will use their newfound powers and weapons granted by their emotions—known as the Catharsis Effect—to fight off the mysterious group known as The Ostinato Musicians as they struggle to escape.

If you are wondering as to keep watching it, or if it'll be interesting enough, just give it a try. It's based on the JRPG developed by Aquria. Story was written by Tadashi Satomi, the same guy that has written the scenario for Digital Devil Saga and Persona

2. Story is the best part of the game, along with the astounding OST, so you'll sure be entertained or not , if you'll decide to watch it. For the confusing part....the whole episode I don't know how to put this but the anime have majority of things you don't understand which is too complicated ...

For those who just want a quick and simple answer to the question "Should I watch this show?" I'll answer that right off the bat before expanding on it: Probably not unless you've played the game it was based on and really enjoyed it.

The Caligula Effect: Overdose has the advantage in terms of pacing, story structure, and character development simply by the virtue of being a game. The story is just a bit too dense to fit comfortably into a twelve-episode anime without losing a lot of great character moments and nuance. So, if this series interests you, I'd highly recommend picking up the ...

This is an anime which delved into some really interesting concepts and plot points, but in the end failed to truly explore the depth they had available. I'm a huge fan of vocaloids, so the plot premise hooked me instantly. However the characters were exceedingly lackluster past their visual design. I found myself struggling to keep up with the three separate white-haired bishounen, and the only female character of note was Naruko, and only because her personality was glaringly bad. They had so much room to work with using the theme of the Johari Window, but instead they just made it ...
