Yes and no. The Henteria Chronicles series is about corruption and NTR. If you look at the splash image for the game the letters N, T, and R are highlighted in red while the rest of the letters in Henteria are blue. The corruption is largely unavoidable and there's only two ways to avoid seeing it. First, you turn off the omniscient POV which means you only see Leto's perspective and therefore miss out on the sex scenes not directly involving Leto, of which there are none unless he's viewing them since he does not have sexual relations with anyone, but they still happen regardless of whether or not you see them. Second, you don't do the content. Of the corruptible female characters only Rose and Cyanna are involved in the main plot with the corruption of Haylen and Lily happening in side quests. N_Taii has stated that he may include the option for Haylen and Lily to remain somewhat uncorrupted if you do not do their sidequests, although his statements on the subject were not definitive and he may wind up not following through on it simply due to workload etc.Out of curiosity since this is my first attempt at this series, is there a "pure route" that the MC can potentially save everyone from corruption? Or only able to save limited characters due to time constraint? Or there is no salvation as everyone is bound to get corrupted via plot and MC is just here for the ride?
Thanks for answering!
The game will have multiple endings that, depending on some conversation choices you make, will result in a few different endings. I believe they can more or less be divided up by NTR ending, good ending, and revenge ending. Which basically means the corrupters win, Leto wins, or Leto breaks bad and if HC1 and 2 are any example defeats and supplants the corrupters.
tldr; if you're looking for a route in which no NTR happens and everyone remains a chaste perfect virgin... you're barking up the wrong tree.
