Zero chance of Haruka being revived in TiTS. Chief reason being because I'm not fond of the direction it went, and also because Fen is already swamped in content so the chances of it getting implemented is pretty much zero too.
I passed the torch on Maki because his content was over 80% complete, with Haruka tho, it would need a full blown rewrite due to subpar quality.
Since I was unhappy with it, I took to reworking the base concept into another character I'm happier with, said character exists and has some plans for it, even had a few scenes written that would make her a follower in Fall of Eden. Sadly the game died shortly after.
So yeah, don't expect to see any more until I can find a new healthy place/project, or learn and build an engine decent enough to make coding the simplest scene not be a freaking nightmare.
