Just watched the latest anime ep and with the 3 on 2 fight after hinamori's kidou web scene she sheated her shikai. When the arrancers powered up to their true forms, she summoned tsubame(?) without the chant and hinagiku had to mention hers and if you remember thatt's one of the requirements to getting bankai!(renji /byakuka fight he mentioned it)
Was it just a lazy moment on the production crews part,im looking too much into this or is there more to the scene than first thought?
