It's mediocre in my book. The same format each of the arc -- New Character introduction > Chat > Problem > Climax > Solution What I didn't like was the excessive use of words. Too random and boring most of the time. Shinobu, Nadeko and her OP were the redeeming part of it though. The Altair, Deneb, Vega episode and the finale were also the best part of it. The author's Katanagatari was better. Watch it.
