Yes, the story has a planned ending.
I don't understand your second question. Are you asking if you have to restart every time you play? No.
Nonono, don't take it the wrong way. I wasn't clear enough, sorry.
Continuously checking for new content every few years was what I was trying to say in the second part.
I do like to repeat the game from the start because I like to have the plot fresh in my memory.
Let me rephrase what I meant, "Is this a live service game, is this going to be like one piece or death note?"
I think that when you answered that the story has a planned ending, that was good enough.
Thank you.
