Wow Fugu thanks for the speedy chapter 40. You said in another post that it'd be like 2 weeks before the next chapter came out... now here you are only 1 week later releasing. That makes me happy.
Great chapter, great plot twist. Lots of reasons why Shin becomes insane is being foreshadowed than in past chapters, so atm, he doesn't seem like a complete monster as previous chapters hinted at.
