The first chapter's name is Chapter 1: Crimson-haired Ruin Prince. As for spoilers for the next chapter, that won't happen until after the second Season 4 DVD volume comes out at the end of this month (8/24) since the chapters are being released with each one. Check out the products page of www.haremking.tv for future DVD release dates.
