Sosuke Aizen

“Fear is necessary for evolution. The fear that one could be destroyed at any moment.”

“...But living creatures are strange. They are made in such a way that they can actualize only what their minuscule minds wish for.”

“If one abandons all other abilities and focuses his strength entirely on a single specialized skill, then he can overcome even the greatest of powers.”

“The Sōsuke Aizen you knew...never existed to begin with.”
