Katanagatari

That's 5 a's out of 6 vowels. Spoiler alert if you do watch the series and haven't completed it.

It ended, with the lead's dying wish to spread the way of greeting people with 'Cheerio!' throughout ancient Japan. Cute. It is used with the wrong meaning in this sense. Cuter.

Final episode questioned heaps, though not exactly too directly relevant to our interests. But I liked it nonetheless, since the core can be added with the details to make them relevant.

I loved this series, and liked the author's style with stories. Looking forward to more quality work from NisioisiN (which if you read backwards and forwards, is the same. Cool pen name eh?)
