Before Genryūsai arrived in the Seireitei and founded the Gotei 13, the nobles controlled all the "resources," "knowledge," "reputation," and "power" in Soul Society...
After Genryūsai arrived, he demanded that the nobles hand over those resources. He wanted to consolidate the resources, knowledge, reputation, and power controlled by the nobles, then build a grand academy upon those four foundations!
In truth, the smaller noble families that had not enjoyed many "resources" considered this a good thing. From then on, they too could learn the knowledge that only the great nobles had been able to study!
However, Genryūsai had one requirement for establishing this academy that touched upon the interests of all nobles: he demanded that talented commoners from Rukongai District be allowed to enroll and learn the same things as the nobles...
Of course, that was not even the hardest thing for the nobles to accept. Genryūsai made an even more excessive demand: commoners who completed their studies at the academy and passed the graduation examination would be allowed to choose whether to join the Gotei 13, becoming Soul Reapers loyal to Soul Society rather than retainers loyal to the great noble clans!
In the nobles' eyes, this was simply unforgivable! Utterly outrageous! Genryūsai actually wanted to use the knowledge they controlled to cultivate a group of "people" with independent thoughts, rather than "dogs" loyal to them. He was fucking asking for death! Genryūsai was actually giving a bunch of "country bumpkins" the chance to change their fates, even talking to them about so-called fairness?!
Unforgivable! Absolutely unforgivable!
If Genryūsai were not the Captain-Commander of the Gotei 13, if his strength had not been so overwhelming that they were completely helpless against him, they would have long since found a way to kill him!
Fortunately, they had recently heard good
