What is it that truly makes love...love? It is this visceral feeling that wells up from inside someone but unlike anger it comes from a place of utter joy. It comes about through the spiritual connection of two people and is so pure that it is almost dangerously unstable.
If we, as simply humans, could somehow harness the power of love we'd have enough to last us until the end of time...but what is it? How do you know the difference between it and lust? How do you know if it is lasting? How do you know if it is real?
If it's Nadeko Sengoku you're asking; chances are before she commands a river of white snakes to dismantle your body she'll tell you that the greatest love is one that's unrequited. If it's Hitagi Senjougahara you're asking; she'll probably explain that true love is only attained when one is willing to sacrifice themselves wholly for their partner. If you ask Kaiki Deishu...such things simply do not exist.
