The end part is more of a teaser and conjoiner for the next update. It will be more individually character focused next update.
I should add I'm really loving Koku as a character. Wasn't my favorite pick early on, but he's slowly becoming one of my favorites with just how off the wall he is at every turn. Definitely has that charm that you can't say no to. And he talked hard smack to the admiral that he might have given the best roast of the cast. My Gog he is precious.
Not "adventure" per se, it's similar to the Building bonds update, where going through each route will tell more of their story, rather than the overall plot.
Because let me clarify a few things: The game focuses on 2 story points: The overall plot which 0.1 and 0.6 does, while the rest is character focused, like the events for 0.2 and 0.4/0.5
