You really need to stop this constant buildup and pencil-sharpening. I couldn't care less about the japanese girl you introduced because you're afraid once you actually deliver the shortstack you won't have any idea how to continue. It was grating when How I met Your Mother stretched itself, and it was shit when George R. R. Martin started 32 unrelated plotlines for them to converge for 5 minutes.
Stop dragging out the pacing and introducing useless filler characters. You keep increasing the scope while drip-feeding the actual content, but making sure nothing is actually happening.
In short, you've set up way too many punchlines, and it's time to deliver.
