Hizumi's probably going to end up on Acidia, so they can definitely trade info! He's the young genius type who's going to already be working by his current age of 16, but he's also still the cheerful friendly kind of kid who's definitely been inserting himself into people's lives because that's how you make friends right??? Right.

Knowing someone on Eonia's also good because he'd be interested in talking medical advancements including technology if Albert ends up hearing anything about that sort of thing! Would you be interested in them having known each other for quite some time, or would you rather they were more acquaintances prior to game start?

Edit: my dumb ass already forgot blood family ties can cross teams so I am also still down for that WHATEVER WORKS FOR YOU AND MAKES SENSE WITH YOUR AU
