@Adamant soul agree or disagree on the nature of their bankais?
Shino got that tousen inspired bankai as sai got that ichibei vibe.
Hinata’s fit and got a rukia transformation to it
I'll say this much, everything looks great from a visual standpoint.
Sai - While I don't hate the control aspect (would make more sense if the ink could turn whatever it touches into his ink constructs), I do question why SAI has this and NOT Shikamaru? The familiarity aspect also makes no sense for a character like Sai.
Shikamaru - Again, considering Shadow Control is his main jutsu, him not having any kind of aspect of it in his Zanpaktou wouldn't make any sense. It's also just lame considering it's just Shunsui's Shadow Game, but usable on other people as well as him.
Sakura - Seems fine but looks and works more like a Shikai than a Bankai. It's kind of underwhelming is what I'm saying.
Chouji - Don't see why it needs to change his appearance so much I couldn't even tell who it was until the name came up. Especially given radical weight loss over time is the drawback and so he should just start in fat form. I also don't see why he would have anything to do with Kido so yeah.
Shino - Easily the best so far, don't have any real complaints with this one.
Hinata - Seems fine though I wonder if her increased vision adds up to the same distance as in Naruto and if she still gets 360 degree vision.
Overall I'd say pretty good but some of them don't really fit their users that much.
