Searching for Nano Banana 2 Capabilities Locally

I’m continuing a short manga using Nano Banana 2, and the results are good enough. What I like is that it learns and maintains character consistency and art style directly from uploaded manga pages — no LoRA needed. Additionally, it’s fused with a language model, so it actually understands what’s in the images and maintains context, making editing through natural language very intuitive.

Is there any local equivalent with similar capabilities? Especially the first part — the language-image fusion isn’t crucial, but it would be a nice bonus.
