A Question on Fusion

[Kurusu Akira]

If you've watched Soul Eater, think Soul Resonance but without one person having to be transformed into a Weapon. They use each other's energy to increase their own energy. Neku uses a Harmonizer pin to facilitate the process, so it runs on his Imagination but both people's energy. Basically, both people give it energy, but Neku gives it a pattern. Since he uses music to focus his psychs, the resonance comes from rhythm; the two people have to alternate attacks with a steady beat, with no room for truly independent action. They have to work together on an instinctual level, basically.
