Even if it's to get close to Issei, which i agree it is and will support to happen, but just having her appear for a random few moments would just be a waste of story space, so why not give a more better reason for Kunou to appear rather than appear for a few parts then head straight back to Kyoto.

Plus i want Yasaka to appear. Might just be wishful thinking, but i want Yasaka to appear and have an illustration of her.
