I also don't understand anything, in "Memories" I see on Naruto and Natsu "you probably don't want to see this scene", but Brendan works fine (after confirming with your avatar near the hut in the forest), and he opened long before I got to the kunoichi village
If the only brendan scene that work fine is after actually forcing it through my avatar yeah that means you got futa on male off.
You can still force that one scene on despite the filter just because I knew this wouldn't be causing any bug.
But brendan also has another scene prior to that, very very early in the game (with Nemona), and I doubt you're able to see that one.
