Subaru letting Haruto have his moment, what a gal.
Ok... about the endgame of this... couldn't Kusabi just... "up-scale" all of them?
Don't get me wrong, platonic love for the characters and all that, but ignoring Haruto (still salty over Ruu's situation)... they deserve to have a chance to live life outside of this little circle.
They should be able to choose what they want to do with their newfound life, they can stay with Haruto if they want or try to find something(one) else.
Sure, a few rules on how to use their powers would be good, as some of them have literal reality-bending powers, but I doubt any of them want to cause problems to others.
