I'm not entirely sure what to make of this. For one thing, ignoring my opinion of the character herself, there was nothing in that segment that a Twitter post and 30 second video clip on it would fail to encompass.
That aside, call me a cynic, but I feel like this is kind of jumping into the character type or image without a lot of context for how she's utilized. Most people I associate with the idea of streaming Pokemon, or almost any subject, don't quite go this hard on their appearance for representing the elements, compared to things like Emotes or Stream Layout being an amalgamation of elements that make up their own brand or identity. Despite the influencer approach, so far the most I get is "Peppy Anime girl with Bubble Gum Electric Pokemon Color Outfit" out of this. If you told me this was a generic Trainer class like "Super Fan" or "Idol Star" I'd just as soon believe that.
She doesn't feel like she has a particularly distinct identity, good or bad, to be influential of anything. In a large-cast game like Pokemon where they typically want many discernible individuals to sell merch for, the character who's supposed to be an eye-catching social media presence just kind of being "there" isn't the best introduction.
Maybe this is expecting a bit much but I would have projected something like this to have been a framing device for the Overview Trailer we got a few days prior. Like, attach something like these parts to the beginning and end as an intro and "Like, Comment, Subscribe" bits, then maybe the recap trailer is framed as a React video where she chimes in with explanations or conjecture about the new info.
