Yumichika is obviously lieutenant-level, or maybe even stronger. But I disagree with Kubo when he says Yumichika would be a good choice. Since his zanpakuto is Kido-type, his bankai would employ Kido as well, and we all know how he hates showing Ruriru Kujaku's true power. Unless Kenpachi gives his squad members permission to practice Kido, I really can't see Yumichika display his bankai.
