Bleach: I'm Not That Yahiko

You ask what the West Branch Office is supposed to be? I'll tell you right now: Whatever the East Branch Office can't accommodate, the West Branch Office will. The nobles the East Branch Office doesn't dare kill, I'll kill. The injustices it doesn't dare address, I'll handle. In a word, I'll take on whatever the East Branch Office can handle, and even more so what it can't. We'll execute first and explain later. The soulfolk have special permission. Let the light of righteousness shine on you rotten, dark, backward souls in the Soul Society, then build a brand-new, bright, modern Rukongai. That's the West Branch Office. Clear enough? I, Yahiko, have a dream: to conquer the Soul Society! (I've already completed a million-word novel. My integrity is guaranteed.)
