Page 408 is where the HICU took over, though it's kind of a slow transition from the remnants of the old story and pacing into the new style. Around the vrisual novel (page 666) is where the new team really starts showing off, but the buildup is totally nessecary imo

I still haven't read all the HS^2 chapters or the epilogues myself, I just skipped to page 408 and intuited what happened earlier from context clues. Kinda similar to "skip to the trolls", really. I recommend.

Most people who talk shit about HSBC haven't read the new stuff anyway ._.
