S41: I used that to contrast how Aizen relied on sealing the flames of Ryujin Jakka within something that turned into a suicide bomber. Juhabach's method ultimately proved more effective; Aizen was still left open for an attack not too long after Yamamoto shielded the explosion himself.
If Juhabach wants to eradicate the Soul Society, why was he planning on leaving after Yamamoto was killed? If he really was out for revenge, the entire Seireitei would be gone.
