Nisioisin just has this way of writing dialogue, whether it is internal or external, that makes me not want to stop reading. Ii-chan even as emotionless as he is, a defective product in his own words, Nisiosin makes him legit interesting. Also this is another brilliant murder mystery. I didn't see the twists coming at all, and yes twists. It's one of those things where even if you were to guess one of the twists, good luck guessing both. While I really enjoyed Decapitation, Strangulation was even better! Between this series and the Monogatari series, people should not sleep on Nisioisin and his light novels. They are immensely enjoyable with fantastic writing.
