You continue to go down - Shunka will warn you that there is a difficulty spike, so maybe do demon route for a bit, but if you are appropriate levels you need to go to the right.
It's not really visible so I actually took a really weird way to get there myself the first time, but you can go all to the right to a next zone when you are in the map Shunka warns you of the difficulty spike about.
im not sure what to do now, like I defeated Haruka there and I see that portal thing which brings me to the end of the world. Where do I go now? If I go up then there is nothing.
Im now at the Lolina route, I finished the first ending. Can someone tell me, is there a way to get the boss back? Or like whats going on - because that would also solve the Shunka route problem.
What options do I have? I would like to do all the endings myself and if possible not have to restart from scratch.
One more thing, whats with the taboo/karma thing - please do not answer if it doesnt really matter for me going for all the endings.
Oh one last question, whats with the red highlighted weapons?? Like what exaclty do the abilities from them do besides having a weird and unique interaction during a battle, like why are they red?
