This will occur some time after Hibiki merges, to no apparent effect. The HiFuMi will then have to take control of her life and start over temporarily merging with Motoko/Zero one by one. When all three have done so, they will then permanently merge with Motoko and Zero, re-unifying Motoko Gettou's psyche. * Got the part about the HiFuMi having to be in charge right, though they haven't had to go out in public yet due to Motoko's suspension, and it remains to be seen what exactly happened to Motoko after Hibiki merged and Motoko had her flashback. * All of them merged permanently.
