First off, let me make clear. You're making the NPCs, but I'll be the ones controlling them.

Second off, the powers granted by the Lostman is far more esoteric than the stuff you'd expect out of normal shenanigans. In general, the ability to change the world isn't related at all to anything that grants you combat ability. It'd be stuff like...being able to see imperfect roses bloom from the chests of others, symbolizing the imperfections of their psyche, or being able to reprogram a human's mind through low-electricity shocks. In this RP, at least, powers that grant straight up combat ability are pretty weak. If you consider their powers as an extension of their innermost desires...people who gain destructive powers are probably a buncha psychos. Those who change themselves can have transformation abilities, sure.

Third, outside of Flame and Ashton's whole coupledom, you haven't explained at all how the older people relate at all to Ashton. Generally, people who are chosen by the Lostman are driven by their own interests and desires, because that's the greatest common denominator between them. And your former assassin dude is going to have lotsa trouble with ordinary society due to the bag of firepower he'd need to put down what basically amounts to supernatural existences. Japanese gun laws don't stop existing just cause the police don't wanna deal with inhuman threats to society, and without the backing of his former organization, it's definitely gonna be harder for him to do...whatever the hell he even does.

Generally, your pitches are lacking the 'why' behind a whole bunch of things, the most important one being 'why are they chosen'. I'd recommend you keep them unpowered until you have those reasons in mind.

In regards to Flame's hatred of Harmoney, I hope you realize that he'd have started out with chasing what amounts to conspiracy theory bullshit. Like, it'd require a sort of ridiculous madness on par with thinking the moon landing was faked to seriously ascribe any 'real' problem to Harmoney.
