Aokiji pricked up his ears.
Why it was called Kekkei Tōta was a question he had never really thought about.
Kekkei Genkai was easy enough to understand, but the word "elimination" always left people confused, as though lost in a fog.

Elder Itachi said with some emotion, "Survival of the fittest; the unfit are eliminated. That saying applies to Kekkei Genkai as well. During the fusion process, one of the Kekkei Genkai disappears and becomes
