Komamura releases his bankai, Kokuju Tengenmyo, against Tousen who claims his powers have surpassed all the Espada and shinigami. Tousen states that it is easy for him to target Tengenmyo’s weaknesses, and that Komamura never believed that an enemy couldn’t be defeated in one blow. In flashbacks, it is shown that both Komamura and Tousen were in squad five at one point under lieutenant Aizen. Komamura states that he became a shinigami to repay a debt of gratitude. However Tousen reveals that he joined the Gotei 13 for the purpose of revenge, and never intended to be loyal. In the past, a close friend of his became a shinigami to fight for peace, but was killed by her husband (who was also a shinigami). As a result he wishes to destroy Soul Society. Komamura states that he has forgiven Tousen but still must kill him for Soul Society’s sake; Tousen is angered and releases his resurreccion, Grillado Grillo, which gives him his sight.
Shinji, who is facing off against Aizen, explains that Aizen does not know his zanpakuto’s power, and that he also has a sword which can control his opponents senses completely.
If Komamura could swing his bankai as fast as he could swing his sword in his normal form, it would be extremely deadly given the destructive power. However he seems to only be able to make a single attack every few seconds, which is strange since his bankai is supposed to mirror him, and not hinder his movement. Not only that, but it gives him many more openings and weaknesses, with much more surface area to attack. As Tousen states, it’s quite an inconvenient bankai. Tousen himself is much stronger now with instant regeneration and high movement speed. He is able to block Komamura’s bankai, making Komamura’s powers ever more unimpressive.
Tousen has a strong sense of justice, but seems a bit misguided. He believes in fighting for peace, and wiping out evil “like the clouds in the sky”; in this case it is the shinigami. It wasn’t the organization that killed his friend however, but a single unsavory member. His philosophical ramblings have some sense to them, as justice and mercy/virtue can lead to two different paths. It is righteous to forgive, but punishment is only fair. However, Tousen believes that one must avenge the dead— an idea I don’t completely disagree with, but still his way of doing it is just wrong. Komamura’s logic is more sketchy, as he states that he will kill Tousen because their beliefs incompatible. The only reason he is fighting is for Soul Society, and without a rationale he is fighting for no good reason. Regardless, the dragged out conversations and arguing was long-winded even by Bleach standards, and the whole episode was pretty boring, especially for those who have already the manga. Like many previous incidents, their past could have been sentimental, but lost much of their emotional impact due to low quality, poor dialogue, bad-buildup, among other things.
As for Tousen’s resurreccion (not surprising he had one), I have to say it’s pretty disgusting. He transformed into an ugly looking bug, but also is able to see with equally-disgusting concave eyes. From his reaction of “I CAN SEE I CAN SEE” I’m inferring that this is his first time going into resurreccion. Being blind all one’s life then suddenly being able to see must be an incredible experience, and Tousen’s reaction doesn’t really make sense seeing him able to identify everything in the surrounding environment pretty much immediately. There’s only so much someone can learn by hearing descriptions alone. Color, perspective, and “ugliness” are not things he could get used to so quickly after coming into contact with them for the first time.
The short segment in the middle about Shinji and Aizen had me beating my head on the table as I did during this part in the manga. Shinji completely gave up the advantage of keeping the opponent unaware of one’s powers. Clearly he was too cocky and was trying to rub his powers in Aizen’s face. However by explaining exactly how his zanpakuto works, Aizen once again has the upper hand— complete hypnosis combined with an insurmountable power and skill advantage. The vizard have so far been quite disappointing.
