Due to a mysterious disease, the genius Iria Akagami has been forced by her family to stay in a mansion on the isolated Wet Crow's Feather Island with only a handful of maids. To keep herself entertained, Iria invites a variety of fellow geniuses to stay as guests in her home, including computer savant Tomo Kunagisa and her unnamed assistant, skilled fortune-teller Maki Himena, famous artist Kanami Ibuki, academic scholar Akane Sonoyama, and renowned cook Yayoi Sashirono.

These visits progress as normal until one of the guests is found gruesomely murdered in the night without a single clue as to the identity of the killer or a possible motive. Tensions rise between those on the island as the killer remains at large, and Tomo's assistant takes it upon himself to uncover the culprit's identity before the murderous events progress any further.

Zaregoto is a Nisioisin show. Who ever told you it was a mystery probably told you PMMM is a kids show, and Shokugeki No Soma is a cooking manga. Bottom line, if you like that Nisioisin flavor you're gonna like this OVA, if you don't, well, at least ep. 7 has a beautifully animated scene directed by Akiyuki Shinbo that's worth the 8 ep. price of admission.

Without reading any of the other reviews I can tell you what they're gonna say. Zaregoto is a slow build. The main character is an edgelord. It's a little bit too much of a stale whodunnit? ...

Mixed Feelings
1. The protagonist is typical nihilist wannabe.
2. The case scenario is typical Agatha Christie's locked-room murder.
3. The irrelevant cool genius Aikawa is typical Sherlock rip off.

At the moment I start watching it, I knew this anime is all about nihilism and existentialism, but it's definitely nihilism for the protagonist, plus it was started with a quote by Nietzsche, the godfather of all nihilism fanboy, so at that moment I assume that the writer of the story must be one of those nihilist f*g. Later, I found out that it was by Nisioisin, and tbh I never really finish the monogatari series, I only watched the ...

Superimposition and retrospect ultimately lead to this abomination. This is an amateur work by NisioIsin developed, marketed, packaged, and sold in a post-Bakemonogatari world. This is the greatest undoing of this work, but to understand why this project failed beyond direct content we have to tackle a series of other shortcomings first.

1. Closed room murder mystery featuring a cast of geniuses.
2. The ever tired and tiring fantasy that is the coming of age narrative.
3. The once-iconic now-generic SHAFT direction style.

1. Vagueness is not profundity
The story is set on an isolated island where an assorted group has been assembled by a quirky patron of ...

The Fall 2016 Anime Season Has Some Actually Good LN Adaptations!

Light Novel adaptations have had something of a poor reputation over the past couple of years in anime. For every actually good one, there are 5-6 terrible highschool harems led by Yuji Everylead the Bland. But this upcoming Fall 2016 anime season looks like it might be the exception....maybe?
