Twin Souls

Twin Souls

"Then answer this, where am I and how did I get here?"

"You're inside Ichigo's Inner World, a type of manifestation of his subconscious. For some reason, I was able to bring you here. Your souls seem to be connected somehow. The only logical explanation is...you are his Twin Soul."

"Twin Soul?"

"The one other half of one's soul, for which all souls are to find and join. The ultimate soul mate."

- Zangetsu and Miria's first meeting and the explanation of Twin Souls to her by him.

Description
Twin Souls are souls that are driven to find and join with other souls thus, becoming the "ultimate soul mates".

When two souls of their destined mates finally find and if possible, resonate with one another, they are ultimately linked and quite possibly be unnaturally attracted to each other even if it goes against their personal characteristics. They could also, for example, unwittingly share or be a participant in each others' dreams.

It is also possible for one (if not both) of the two souls to draw strength from the other and get stronger as in the case of the former number 6 Claymore warrior, now leader of the Seven Ghosts, Miria, who drew strength from the Substitute Shinigami, Ichigo Kurosaki's, spiritual energy thus, increasing her Yoki power to an incredible degree.
