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.

Until the final moments of the second episode, it is extremely unclear what Zaregoto is supposed to be about, or even what it wants to be about.

Little of significance happens during this time: character introductions interspersed with surreal 'SHAFT-ness' (this should be coined as a word if it hasn't already) and philosophical discussions about the meaning of life and why the protagonist is apparently such a big fat loser. Cool, so everyone is a weirdo, and the setting makes no sense, but why are we supposed to care, again? I expect most people who are not already fans of Nisio Isin or SHAFT anime read more

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? read more

Zaregoto, much like most other Shaft and/or Nisioisin productions requires a certain mindset as well as expectations to enjoy.
While I don't like how pretentious saying this sounds, I still have to say it:

This isn't some 'Whodunnit'-rhomp you can watch after work or school while being half asleep. To truly get most out of it, I recommend really focusing on it as much as possible.
That, or get drunk and enjoy the pretty pictures and lovely sound.
I've been guilty of that too occassionally.

Now on to what you can actually expect.

Zaregoto is a character study donning the guise of a murder mystery, with some good indulgent waifu material, read more

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 read more

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?
