Nobody knows if thats her bankai or not, she just calls it minatsuki, which is the name of her sword. And nobody in the manga describes her "bankai" either. And the fourth squad isn't just healers, If you've read the manga at any depth. The fourth squad are still fully battle ready shinigami, But they Are also skilled in healing arts. It mentions it several times, and being captain means she can't be too weak, expecially being able to heal herself in battle would be a major advantage.
And your corrections don't really affect what i was talking about.
I agree with the part on kisuke, thats exactly what i said, he's a strong captain level, and he uses crazy techniques with his "Blood mist" shield/wave as well using his expierience from the research squad, for battle modifications, and using strange expieriments in battle. so i agree with you, but his strength does not just lie in his intelligence, he's really strong in general. Probably the strongest or second strongest in the human world.
And for how strong byakua is? the reason for his loss, doesn't matter as much as how strong he is overall. And he didn't lose to the hollow inside ichigo, it just stalled him and even'd the field between him an ichigo. And i don't know if we read the same manga, the whole time ichigo is in soul society, he refuses to accept ichigo as strong, or even a real shinigami, and he didn't even believe that his ban kai was real. Yet ichigo overcame his "pride" and byakuya admits he lost because ichigo's blade shattered his, he even phrases it as, "your liberalness has shattered my blade of pride, the victor of this battle is you"
And inoue is battle weak, she can't do anything in a fight so far to anything stronger than a weak hollow. sure her powers are amazing, but i mentioned that, and the fact that her powers are TOO good. And if she ever gains perfect control that is liek, where the manga should end.
